A printed hollow screw adds some strength and can be used to hold everything at its place during the build. Unit price / per . The outside is about 20mm. I will have to find a way to wire the rotation sensors. I also dit put a flattened transistor cooling fins on top of the CPU? Thor has been developed using only open source tools: FreeCAD for the 3D modeling, KiCAD for the PCB design and GBRL as firmware for the control electronics. Im back! It took me a few hours to understand the values that I had to set (track width, drills diameters, etc.) In its upright position, Thor is about 625mm and it can lift objects up to 750 grams. Below all the new/changed parts of the Art 3 upper body and the Art 4 shaft. There are one assembly file for each articulation and another one called Assembly.FCstd that contains the whole assembly. Assembly There is also room for a 40x40 fan. Visit us! And you will be able to help, give/get feedback and share your ideas, progress and modifications with other community members. On the axle it will be mounted like this: Below the new gears. This way a Gap of about 14 mm is created between the Art56MotorCoverRing and the stepper motors. It also supports up to 8 endstops (1 per motor) and a pwm output to control the robot tool. Then press it into the hole. If possbile, please download from the wiki to see the more pictures. Tendr algn documento sobre la cinemtica directa y la cinemtica inversa del robot. In its extended position, Thor is about 625mm high and can lift loads up to 750 grams. The Poles call it Woz Niebeski, the Heavenly Wain. Some are printed with PETG. I have already lose lots of printings using it until I discovered I have to deal with my rooms temperature too. I want a robot that is able to act as laser engraver or mill thin plywood. Generally shielded wires are only grounded on one end. Below the gripper. Because of the fan holes the ART5 covers didn't fit anymore. The main purpose of this project was to design a robot that could be used in universities and schools to teach robotics.With this in mind, the design had to be affordable and accessible. I had to choose stepper motors with mechanical reduction for the second and third articulation in order to manage the torque generated in these articulations. I would like to do that by making this Axle hollow and use large bearings on the outside of the shaft. thor endgame . It was done with Blender and embebed in a website thanks to the Blend4Web framework. Log in. Unit price / per . Designed for low height printers, thank you again Danny :), On the right, the BaseBot modification made by Ctrl-Alt-Dude for 190*190mm print area. I use some Alkotip wipes to clean the glass plate before printing. Great Project! Sorry for the late reaction.Most of the parts I printed are printed with PLA. Open Source Reconfigurable Robot Arm for Learning STEM. You should And the upper part. Thor has been developed using only open source tools: FreeCAD for the 3D modeling, KiCAD for the PCB design and GBRL as firmware for the control electronics. Of course using OpenSource software, KiCad again. The small orange gears and Pulleys are (going to be) connected with a screw. Drag and drop the buttons as shown in video. 2. Thank you very much! Could you make a BOM list or at least what additional orders you have done that are different than AngelLM's BOM. I already ordered a few different sized 6xxx series ball bearings. This is an important process and you should be familiarized with it, as you might have to disassembly some parts in order to fix or adjust some things in the future. Instead of integrating a gripper into the design I decided to make an adaptable design making an interface between the end-effector and the robotic arm. The Art 3 lower body. Use a electrical screw driver to screw theArt56GearPlateAxleHolder_01 on the axle. I was looking for a 6DOF robot arm to print. Just hold the inside and the outside of the bearing in place and fill the hole with balls. One part with the big gear and one part with the shaft. Use a flat tool to push the bearing in it's hole. The upper bearing. To set your password you will have to follow this link. If you open the design file in Fusion 360 then you can see all printed and non printed parts. The sensor for the 2nd and 3rd Articulations are placed in a similar position as the custom ones, I modified the Art2BodyB piece adding fixing point for them. But it was difficult to print. Below the latest step files and stl's of al the new and changed parts. Just a small preview. Hi Zubiar, which part of the connections are you missing? This project was - Day 16.zipThe Body4 and Cover5 parts are untested. Easier assembly: the Silkscreen is a nice helper! I have only tested it using the 3D models. In the image below on the top the motor mount (and motor) are touching the mount with the screw hole. Hi Luiz, there was a problem with the Google Group but now it's fixed and you should be able to join it! 3. So I returned to PLA and decided to add fans to all parts with motors. Right click and choose "Save to stl" to make it printable. Your doing fantastic work! Thingiverse is a universe of things. You can find the source files at the Github repository. Printing Profile: I recommend to slow down the outer shell speed at least to 50% of its normal printing speed in order to get accurate results on holes, gears, etc. Designed in FreeCAD 0.19 and based on an old redesign I started a few years ago, Thor v2.1 is now available for download. Its configuration (yaw-roll-roll-yaw-roll-yaw) is the same used by most of the manipulator robots on the market. Nema 17; L=40mm; Holding torque: 39.22 N.cm, Important Announcement: Community migration & Thor v2.1, Danny made some modifications to largest pieces, BaseBot modification made by Ctrl-Alt-Dude, https://www.thingiverse.com/thing:1611164. The assembly process is pretty similar to every version of Thor up to date. For the first three ones was an easy task, but the sensor located in the Art3body piece for the 4th Articulation had to be pretty small to not collide with the Art4TransmissionColumn piece. I grounded one side on the ultra board. Its recommended to use the PC for opening this interactive instruction manual, as the website loading time takes time and its not responsive for smartphone displays. Then I have 2 parts. the robot arm assembly as claimed in claim 5, wherein the first transmission mechanism comprises a first belt transmission assembly, and a first rotary shaft, the first belt transmission. (A rotary encoder makes it possible to continue rotating). Releasing the source files and doing so under an open source licence was the best option: anyone could study any element of the robot in depth and, moreover, modify or adapt it to their needs. The project started in 2015 as a final degree project called Design and implementation of an Open Source, 3D printed 6DOF robotic arm. Check the complete Sr. Ferretes Thor Playlist here. The arm is designed to be manufactured with minimal fabrication effort: the only instances of manual fabrication are drilling the arm's base plate and linkage body tubes, sawing the linkage body tubes, and heat-setting several brass inserts into 3D printed parts. (It takes a while for the browser to render. Already have an account? An Open Source 3D Printable 6DOF Robotic Arm, 20 units have been built in at least 11 different countries. The hole in small orange gear is much bigger then the GT2 pulley. Fun Stuff. This version of the model is downloadable here: http://a360.co/2BDyFyW. This makes it possible to lay it flat on the table or put it upright. It is space-saving and can be reprogrammed quickly to be used with different machines. (You need a shielded 4 wire cable). Check his channel for more awesome projects! These would be the key features of Asgard GUI: (features marked with a are already implemented!). This board allows to control up to 8 stepper drivers (instead of 7 of the previous version). Hence, ground both ends. 2 bearings and the pulley are 27mm. The author has designed with FreeCAD all 3D printable parts, along with sensors, actuators and other materials. The Art5Top Covers are almost finished. I also changed the orientation of the mounting screws between the upper and lower body so It can be separated without removing the covers of Art 2. For the two last DOF I chose smaller steppers with the purpose of reducing their weight. And let's be honest, although it has been useful, Thor's Google Group mailing list is not pleasant to use. Select any button and assign the "press char" and "release char" as shown in fig1 and Table2. EDIT: I forgot to say that I also did a Frequently Asked Questions in order to answer them :). Thor Open Source Robotic Arm from Spain Thor is an Open Source and 3D printable robotic arm with six degrees of freedom developed by ngel Larraaga Muro from Madrid, Spain. I will be happy to know what do you think about this! It's the crossover episode you've been dreaming about! The axles can be "screwed" into placed by placing them into a electrical screwdriver. Now it can be printed like below. Sepio I downloaded your STEP files but my Solid Works couldnt import them . This interactive instruction manual is something I made years ago for the test version of Thor v2. This is the buildlog of the Thor+ robot I'm building right now. Unfortunately the film was cancelled before we finished. If all parts can rotate and stay into the right place then it will work. The axle hole in the plastic gear is a little bit bigger. Now it should be no problem to use PLA. I already mounted the motor. In the future I might change the custom ball bearing because it has to much slack. If the small gear are rotating in the opposite direction then Art 6 is rotating. So, without further ado, these are the changes I made in the design (on the left side the old design and on the right side the new design): The sensor for the 1st Articulation is now fixed to the BaseBot piece. luiz.csilva82@gmail.comThank you. This is how it will look with the gripper mounted. The wiring of the display, the meters and the buttons. in order to send it to the manufacturer but it won't happen the next time >:D.

Shared under CC-BY-SA 4.0 License under CC-BY-SA 4.0 License I'm thinking to use mine for automating my 3d printer into a mini manufacturing line. You rock! Privacy Policy To be honest, until now it was pretty tricky I made my own sensors using a DIY CNC for the PCBs and soldering the components by myself. I am still learning how the arduino stuff works. So I decided to redesign it. Also, I designed covers and protections to reduce the risk of entrapment while the user is manipulating the robotic arm. I wanted to hide every motor and every single wire to make it more aesthetic. I have many questions! The gear-head can be screwed with 6 self taping screws on the shaft. Were there any exceptions to the 3D material use for your print on certain parts. It will be a tight fit. Do not hesitate if you want to collaborate in the development, help is always welcome! Dont worry if you mess up on any of these files, you can always download them again. It works with 5V and gives a 3.3V output which can be used on both the 3.3v due and the 5v arduino. Thanks Sepio,Which firmware did you use for the ultratronics board? See you there! Its been a long time since the last time I wrote a log! Already have an account? If everything fits then I will make it downloadable below. I did my best to gather all existing project documentation in one place. For every piece there have been a lot of iterations behind the final one. The more people are interested in this project, the more feedback I get. I have a Tevo Black Widow and I will try to do a amazig job as youve done. And I designed a "shield" to make possible the control of 7 steppers. The big hole is for the SD card. Are you sure you want to remove yourself as I added support for the LPD3806-600BM rotary encoder. Below on the bottom the old version. Sorry, I'm building a cheap Thor design, and I need the schematic of the PCB to control the robot motors, I saw the original board and it is impossible to make it with the elements that I have, so I need the schematic to be able to do it myself. The one I was using had many mistakes (a man may learn wit every day) and I got tired of botching it. Eco-friendly wood sheets, necessary spare parts . And the lower part. your work is amazing, Danny has done a tremendous piece of engeneering and you must be very proud to have Danny saying that your work is fantastic.

The last few weekends I made an enclosure for the power supply. 1.24 MB - I never used SMD before, but there's a first time for everything haha. The rotary encoder I used (from ebay). Lets try to not reinventing the wheel! created on 08/03/2016 Posso fare quanto detto in precedenza, un patto di imparare tutte le modifiche? You can use self threaded screws or "5mm long m3 Threaded Brass Knurl Round Insert Nuts" to mount the back to the front (just put them on a long screw and user a lighter to warm the nut. Attach the Claw. I want to add a PCB to connect the electronics in the Upper part to the slipring in the Art4Transmission column. I want to remind that there is a Google Groups community with 90 members in this right moment where you can ask, share and read about this project! [3] [4] The cost of the whole materials is under 350. Time ago, Danny made some modifications to largest pieces, splitting them and making them printable in 180*180mm bed area printers. The last few days I changed some parts. But that wasn't working because the robot arm could collide with it. The fan intake. I don't know why but the notifications were off :(. Do not worry about that cut, there are no circuits in that zone of the PCB, so can be cut gently. A screw is used to hold the big gear of Axle 6 on top of the small gears. 11/05/2017 at 11:57, Zip Archive - The initial idea was design a DIY PCB board, but due to its limitations and how cheap is to manufacture it in China I decided to design a better control board. From the beginning, the project was very well received. Afterwards, remove the stickers. An error occoured on phase two. If you run out of screws, feel free to pull some screws from the base of the robot. Thor then buries the armor under a mountain slide. I have added a piece of black tape on the Axle 6. Thor is an Open Source and printable robotic arm with six degrees of freedom. Hello everyone! The main purpose of this project was to design a robot that could be used in universities and schools to teach robotics.With this in mind, the design had to be affordable and accessible. Sign up. Don't blame me for my question. This makes adding the belts easier. It has been 3 years since I released Thor! The GripServoMount has some extra room for the servo (on the bottom). So I might redesign this. Materials. I2C with the PS4 controller LOL First you need pull up resistors, Danny warned me about this and he was right.Second I think there is a bug in the firmware on I2C that does not happen when you use Serial. Feel free to add anything! As a cable you can use a cut USB cable. Thor ControlPCB ControlPCB is the board used in the Thor project to control the stepper motors that drive the robotic arm. Finally, I chose optoisolators and a micro-endstop in order to establish a home position for the first five articulations. It can be assembled in several ways for multiple tasks such as moving objects. To make the experience fit your profile, pick a username and tell us what interests you.

The axle with the holder can now be fitted into the big gear. Next week I can tell if everything fits. The downloadable version (below) is 1mm thicker. The Art4UpperBody is currently printing. Put the slot in part #7 over the nut and start to tighten the screw. You should The left orange parts can be glued and screwed together. 17.57 MB - If you want to keep the EMI outside the cable, ground one end.So if a signal is small in magnitude (think audio signal like microphone circuit) ground one end to keep interference from outside corrupting the signal inside the cable (including interference created by a ground loop if you were to ground both ends).If you are connecting something like a strobe signal (large AC signal) go ahead a ground both ends as goal is to make sure what is inside doesn't radiate to the outside (groundloop induced corruption of the large strobe signal is a non-issue).In the case of an RS-232 signal you have a fairly large signal [5V or more Peak to peak) running at almost 10KHZ baseband frequency (or more)]. I used Dannys list. It's a pleasure to watch your progress, I even want to change my weak parts by your ideas. I want to cut it on the left side of the tape. In this page you will see instructions and videos that may not be for the lastest version, but in general is applicable to almost the entire assembly process. This way the electrical wire will stay out of the belts way. I recently discovered that I can build a 6DOF arm with my printer. and last updated 2 months ago. :). Of course, I shared it on the Thor's Github repository. You can watch the whole process before assembling your own and see the tricks and difficulties. None of the 6 DOF is a end-effector. The wrist in particular is superior to AR2's. To make things easier, I was looking for a single model which could fit in the 4 articulations. Join us! So I already added a hole to the Art56Interface (on the right side). There is enough room for the belts. -Art56SmallGear_For16x7PulleyShaft_01.stl. An upper robot arm is. Woah, time goes by really fast. 09/17/2017 at 15:10, Standard Tesselated Geometry - You can also attach a camera or solar panel. Thor is an Open Source and printable robot arm with six degrees of freedom. As you see I have designed it for THT and SMD (1206 package) components. Sure it is a great project to learn lots about robotics, firmware and maybe ROS too. Best,Naturobotic. I am going to make the hole smaller for the pulley. This way its easier to keep in your hands and if the cable is long enough you can stay out of reach of the robot arm. 1.22 MB - You are about to report the project "Building and improving the Thor+ robot arm", please tell us the reason. The enclosure has an emergency button to cut the power of the 5 and 25V line and 2 separate volt and amp meters with a cut of switch for the 5V en the 24V line. The two holes on the side are for ventilation. One step closer to fully open source process automation! In this way, access to knowledge can be guaranteed to anyone, anywhere, without any economic cost. I'll send it to the manufacturer as soon as I finish another PCB I'm designing. If both the left and right small orange gear are rotating in the same direction then Art 6 is going up or down. Tip Question Comment Be the First to Share As you may have realized, all of the hardware I have chosen is commonly used on DIY 3D printers. The AR2 doesn't have nice thick box section for the bicep, so it's more flexible in rotational and torsional loading. Attach the last servo to the claw using the screws. Drive Gears convert the high-speed output of the robot servo motor into a lower speed, greater torque servo output. Or press the download button on the right top to download the model). Thanks Sepio!, Since the original Thor design do you think that Thor+ and your changes have increased the max payload from the original 750g? There is a nut in de orange part with the axle. I think that it wont be hard to find that kind of sensors in other online-shops, but I tend to use Aliexpress because of its large catalogue. To date, more than 20 units have been built in at least 11 different countries. This is the way Danny designed it. But I don't really understand how it has to be mounted. Make the Control PCB and weld the components! So, engineers developed the robotic arm to imitate the elbow, right arm, hand, and elbow movement. There you can download all formats. After days of searching, I decided to make my own. I used two rotation sensors on the Art56MotorCoverRing. Assembly robotic arms are used to automate tasks that involve putting products together including electronic components, machinery, furniture, and automotive assemblies. My version was 15mm and the hole is 16mm so I used some tape to make the axle a little bit wider. Click at the link on the bottom of this blog. This compartments is optional. Complaints from me: - use of 0.4A Nema 17 motors. Where can I find. The printer is printing the new components right now.I made the Art4LowerBody 15mm taller. The new version can be download here. Releasing the source files and doing so under an open source licence was the best option: anyone could study any element of the robot in depth and, moreover, modify or adapt it to their needs. more pictures, please visit the makerobotix wiki. The m3 nut is 5.5 mm the hole is 5mm.. 09/10/2017 at 17:35. Sorry for the late reply! I added a bearing. By rotating the inner part the balls are traveling to the bottom and the hole is free to insert the next ball. Thank you too! Its configuration (yaw-roll-roll-yaw-roll-yaw) is the same used by most of the manipulator robots on the market. data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAKAAAAB4CAYAAAB1ovlvAAAAAXNSR0IArs4c6QAAAnpJREFUeF7t17Fpw1AARdFv7WJN4EVcawrPJZeeR3u4kiGQkCYJaXxBHLUSPHT/AaHTvu . An Open Source 3D Printable 6DOF Robotic Arm. Then I laid the test print on the green cutting mat and it was already perfect the first time. Thank you so much for having such awesome documentation. There is also room for one or 2 rotation sensors on Axle 6. In some cases, we will replace or repair it. I am trying to build my own Thor+ robot. Then, take a box-end wrench and slide a hollow metal bar over the handle so you can add length and give you more torque to turn the wrench.Fit the wrench over the head of the stuck bolt and hold it at the very end of the bar.. "/> based on your interests. 6. Because I never found any video of people using their robots for anything useful, I want to ask what it can be used for (really). This way it can still be mounted together and the shaft is fixed between two bearings. We found Some design solutions are inspired by commercial robots, others are the result of hours of work and others are just serendipitous ideas. You will find the full resolution image & source files at the Github repo. I moved the mounting points for the upper body to the upper body. If you open this file in Fusion 360 (free for home use) then you are able to open the tree. The second version can be downloaded below. Step 25 is simply to leave the machine screw in the assembly to make it easier to attach it later on. Most of them are named correctly. Privacy Policy Now take a slant 2by1 and attach it to the 1by1. For the transmission of the third, fifth and sixth articulation I have used GT2 Pulleys and GT2 Belts. I tried to create stl files from the fusion 360 project and hit issues because the claw alignment is slightly out. Love the project. Since a few weeks I'm receiving a lot of questions/feedback/information from many different directions (email, Twitter, Hackaday, Thingiverse, GitHub, Wevolver, etc.). As this project has attracted different kinds of people, I thought that it could be nice to simplify this issue: making Thor compatible with commercial sensors instead of creating the custom ones. This way, actuating over the two small gears allowed me to place the steppers as lower as I could, transmitting the movement with GT2 belts and reducing the torque generated by the motor's weight. Take a 1by1 Lego for the base of the arm. Recently I have received several questions about the sensors Im using to establish the home position of Thor (opto-couplers, opto-transistors, opto-switches whatever). 3D printer: I have used one with 300x220mm of printing area and 0.4mm nozzle. Now you can add anything interesting from the inventory on that clip. I'll be posting there my progress and changes too (I will still doing that here too). First and the most necessary: Reverse current protection circuit. We will send you an Amazon e-gift card for the purchase price of your covered product. Making the arms of the robot. . can you extend the reach? And voila! This time I have taken it up with enthusiasm and I think it has been worth the effort. The only corner that wasn't perpendicular was that of the cheap chinese geo-triangle My free tip. Make sure the gears align perfectly. It's also a service that Google could eliminate from one day to the next, losing all the information there. Are you sure you want to remove yourself as This is the top part of Art 3. Exciting! Thor 3D printed Robots The Thor Project The Thor Project is a project created by AngelLM, who wanted to create an Open-Source 3D printable Robotic Arm. Iadded fans to all the parts with motors because they will get hot. You may encounter this issues (mine was with a PS3), https://hackaday.io/project/16483-building-the-thor-robot/log/56239-ps3-controller-i2c-concerns. Please add me to the google group. Why not use the shaft of the stepper of the third articulation as the support point for the second articulation axis? The lower yellow ring and the black ring above are optional. I want to use PWM and a thermistor to cool those motors below the 65 degrees PLA can handle. I will take them all in account! That's why I decided to make my own program to control Thor. There are (at least) 4 Thors assembled & operational around the world and another 17 being built! Give Feedback Terms of Use Not a member? Learn More. A tag already exists with the provided branch name. Malfunctions covered after the manufacturer's warranty. I going to design 6 DOF gripper arm, can you help me in design:). What firmware did you use for the Ultratronics board and the Arduino nano? A robot arm assembly a base unit with a shoulder assembly rotatably disposed on the base unit. The second version is printing right now. I feel confident it won't be long before RO is talking to the firmware and any THOR owner can drive their arm from the software. This way it can be tightened better. If you are reading this close to the publish date, you will find the new PCB files in the ControlPCBUpdate branch. Using optoisolators instead of mechanical stop allows it to rotate more than 360 degrees without colliding with the sensor. Thor on the other hand has essentially the same designas a modern lightweight arm, with modifications for very low cost. Also, I migrated the design to FreeCAD in order to have the source files too ;), EDIT 21/12/16: I have migrated another 2 modifications to FreeCAD :), On the left, my remix of Art4Body modification made by Danny. There are few laws that apply across every one of the million and more worlds of the Imperium of Man, and those that do are mostly concerned with the duties and responsibilities o [ Assembly Tips ] - 149-pcs-project requires great patience and carefulness. Check soon my fork of the grbl repo to get the lastest firmware for the ControlPCB board. After a few tries the pulley was having the right length. A lamp made of 930 laser cut parts in a heavily geometric design, An octopodal robotic platform for rough terrain exploration, A personal project to overhaul my home lab setup, and install new benches, Mini mill made from cheap Chinese parts and a pile of 2x4 scraps, Day 19: Taller Art4LowerBody + New Art4PCBBody. This robot kit was designed for educational and hobby purposes. Now its finally printed and its available below. Perfect for this purpose. Its configuration (yaw-roll-roll-yaw-roll-yaw) is the same one that is used on most manipulator robots that currently exist in the market. This will allow more users to print Thor. We have opted to create our own Robotics Control Board, the DEVIA. But why are you connecting the usb host controller to the analog pins and not the 2 dedicated I2C ports on the right? If you open any assembly file you will see how printed parts and other components (bearings, motors, bolts, nuts) are assembled. There is some room for the air to escape. Many people liked the robot, but not the way to control it. Since then, this project has continued to develop little by little. The upper part with room for the PCB. Below all the parts for this custom bearing. There is just enough slack to mount the belt. They will freely rotate on the Axle and are driven by two motors. The story of Thor losing his arm begins in Marvel's comic event, Original Sin. Any chance you can share the software you used to control the steppers? I splitted this axle into 2 parts. One for a 20x6mm pulley shaft and another for a 16x7mm pulley shaft. The shaft is thick enough to use 3 3mm screws to fix both parts together. No problems detected after it. But at this point, I don't really know the state of that GUIs. There is a small gap between the orange Art4 part and the Black Art 3 part. Tip Question Comment Step 3: Intall the Arm this is the step for the arm. This has been possible thanks to the 2 layers board, and it will allows to simply connect a ribbon cable with a 2x18 connector without "hacking it". First attach the left assembly to part #7 with a 12mm screw and nut. That doesn't work ;-). Hi, I'm assemblyng thor, but i can't understand how the art 3-4's bearing works. For some pieces supports are needed. Robotic assembly is likely one of the first images people have when they think of industrial robots. Create an account to leave a comment. Very interesting project on that you are working I am also doing the same job here onpjsbuildingservicessite and this will help me to boost my projects quality. If you want to know more about this project, visit the Thor Website, where you will find documentation, manuals and a forum to solve all your doubts. Your arm is already now. Automotive manufacturing - essentially the first industry to standardize on robotic automation - utilizes heavy-duty six axis robots to increase capacity and improve quality in their manufacturing processes.. Today, assembly line robots stretch far beyond automotive, as we see more and more . The automotive industry was one of the first to adopt industrial robots for assembly. After a question of Olaf I tried to tilt the display on the base plate. $3,130 00. (In a later stadium i used a knife to remove the bump. This way the screw thread will work. It has been possible thanks to the FreeCAD. A big way to enhance these 3D printed robotic arm projects is to integrate technology that everyone has access to. Everyone can access, everyone can ask/answer/show, it's easy and clear and it's free. The lower bearing and the ventilation holes. Special thanks to @angelILM for producing the STL files and dimensions on request. Thor is more modern engineering-wise though. The makerblock rotation sensor doesn't support a full 360 degrees rotation. The UR robot can be used in most assembly applications. thanks!

In this way I want to share all the info I have with you all. Features: dimensions:24,7-cm H x 19,6-cm W x 26-cm D; customizable framework; Creative Commons Attribution-ShareAlike 4.0 International License. When the small gears rotate in opposite directions, the big gear rotates around its own axis. I will start my Thor in Jan. 2018. I added the screw holes for the covers. The green ball are 6mm airsoft balls. There is a small bump on the axle which can be aligned with the hole on the gear. Below a rendered preview of the new design. Sorry but I dont have a BOM. This is the first version and there are two small problems. I used some tape to hold the plug in place. In its extended position, Thor is about 625mm high and can lift loads up to 750 grams. And this is not the only change I am proud to announce. PTEG is a very dificult filament to work. Is used some foam tape and some electric tape to make the slipring a little bit thicker. Step 1: install the bearing and base Tip Question Comment Step 2: install the arm, since the pictures are two big. I tried to calibrate the printer multiple times but every time i measured the corners with a geo-triangle they where not perpendicular. . Besides the aesthetic changes it is worth mentioning the new features: And that's all, I hope you like this new news and see you on the new website! Blow molded Thor hammer costume accessory; . EASY CLAIMS PROCESS: File a claim anytime online at www.Asurion.com/Amazon or by phone. From now on, the google group will be obsolete and only the new forum will be used, in order to centralise all information in one place. Click open in browser en you will see the latest version of the modal and a download button in the upper right corner. Save $20 Quantity. After cleaning I use a (very) little bit of 3DLAC. The DFRobot 5 DOF Robotic Arm Kit consists of all of the servo motors, brackets, fasteners and other hardware that you will need to construct a small but powerful robotic arm complete with a gripper mechanism. I hope you like this project as much as I do,ngel L.M. The bearings I used are 6806 2RS (30x42x7mm) and 6810 2RS (50x65x7). Then somebody pointed me to theThor OpenSource 3D printable Robotic Arm from Angel LM. Thank you - Congratulations again. Never found any information about precision. I loved this design but I was missing the feedback sensors. This follows on from the controversial $432,500 sale of a robot-produced artwork titled "Edmond de Belamy" in 2018. The ART56 interface place also contains a hole for future usage. The first thing was to find a cheap commercial sensor which could fit inside Thor. 11/05/2017 at 15:24, step - Since then, this project has continued to develop little by little. Its becomes extremely hot. On the right side of the servo there is some extra room. Thor: OpenSource 3D printable Robotic Arm 1-30 of 126 IMPORTANT: This Google Group is obsolete, the community has been migrated to the new Thor website. You will need to install FreeCAD in order to open any FreeCAD file. (I might even be able to keep the shaft hollow to guide some wires). Did you ever test your robot or even did you ever powered it up? Thor is an Open Source and printable robot arm with six degrees of freedom. Assembly robots offer a range of capabilities that can allow it to position, mate, fit, and assemble components or parts for a product. Small ball bearings will be added to the small gears. Being so affordable, I think almost every school/university/maker could make good use of at least one! I used the Art2 body parts as a mounting template. Have a nice Christmas eve. I want 2 bearings to keep this axis as steady as possible. The result was precise, almost without backlash (after some printing sla - He made an awesome work, and I wanted that modifications to be in the main repo, so I added it! People need to be able to communicate and convey their message to the customers to run a successful business. Communication is to receive or send any kind of information. Easy to use and accurate hand eye calibration which has been working reliably for years (2016-present) with kinect, kinectv2, rgbd cameras, optical trackers, and several robots including the ur5 and kuka iiwa. On the inside there is a small black cover on top of the SD card reader. Thors community is growing fast! The final design had to be compact and safe. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. This project was The wheels are driven by two rotation servos, while one servo is used to lift the arm and another servo for open and close the gripper. The sensors fit, but presumably the connector of each sensor will have to be replaced with other flatter. Grimm cites Herwagen, probably the Horwagen of Bayer and the Hurwagen of Caesius; while a common English name now is the Waggon. The shaft itself is wide enough for another 24 wire slipring. Step 4 After, connect the robot arm based part. This is the Thor robot arm with a lot of addons and improvements. Animated by a nearby lifeforce, it battles Thor to a standstill, Loki is forced to intervene and stop the Destroyer using lethal force when Odin threatens to kill him. Kinova produces the JACO Assistive robotic arm, a six-axis robotic manipulator arm with a two- or three-finger hand to improve the life of people with mobility issues. There is a growing need for high-speed, robotic assembly of small parts. It has a powerful ARM Cortex M0 processor and a bunch of input/output ports + sensors. There isn't much room but it fits. You can design an intermediate piece that fit with the interface on one of its sides and with the tool on the other side. I changed the gripper mounting plate to a trapezium so both parts will stay together and the existing screw holes will keep them together. Yay! Explore the development of a DIY EVI Windcontroller for survival of this great instrument, An open-source, 3D printed, high precision robotic arm with trainability. 864.73 kB - (The gear has to be able to rotate freely on it's axle. There just isn't enough room for all the wires. The extra holes are for setting the belt tension of the ART5 and 6 motors. (But his downloadable STL is different). The middle part with the ring contains a nut on which the Art 6 Axle with the big orange gear is mounted. Sign up. It's my first time programming something that doesn't use the terminal for the user interaction so please be gentle with me hahaha. They will need protection when working in corrosive liquid environments. Then put the other bearing on the bottom side. Instead of grippers designed to assemble cars on an assembly line, the robots have x-ray emitters and sensors that can be precisely positioned on either side of the horse's . Also, from the very beginning I wanted everyone to became part of this project and share all the information. There is about 29 mm room on both sides of the axle. Look at the two new black spacers on the outside of the axle. I ask before starting to print the arm. Danny asked about my printer. More advanced systems will feature six-axis robots, which can move more freely than an XYZ robot. Already have an account? I might redesign Axle 6 again. The Robotic Arm with Gesture Control (Arduino + Kinect) This project involves directing a robotic arm with gestures. This GUI is called Asgard and is OpenSource too. Thor-robotics. All Universal Robots' robotics arms are certified IP-54. It worked well. I ordered them to PCBWay and my experience was great! First seen in the Temple of Darkness in Asia, the Destroyer is used by Thor's arch-foe Loki against him. If you have some suggestions/tips/comments please post them! One thing is clear, this project has become known, at least more known than I expected at the beginning, and I cannot do other than thank you! Workplace Enterprise Fintech China Policy Newsletters Braintrust rust escape string Events Careers 4k security camera system with audio First put a bearing on the top side. Let the oil soak for about 20 minutes so it can lubricate the threading on the bolt and make it easier to remove. AngeL said he used PLA for all parts? All rectangle where shaped as diamonds. This is the top of the display. The board of this sensor has to be cut to avoid the collision with the Art4TransmissionColumn piece. The fan is mounted on the inside. Using a lot of platforms is convenient for spreading the word, but not for focus the information That's why I decided to make the Thor mail-list community. Below my print setup. The small black part is the plug. I also added the GripGear.stl (which was missing in Danny's version). I added some holes for the nuts on the ring which fixes the Art 6 Axle. Details I was looking for a 6DOF robot arm to print. Hi Emre, I'll fix it soon in the Github repo, meanwhile you can get the gripper in thingiverse: https://www.thingiverse.com/thing:1611164, If someone can add me to the google group Ill appreciate it a lot :), Hi Ivan, there was a problem with the Google Group but now it's fixed and you should be able to join it!Sorry for the late reply! And then I found the'Thor' robot with addons and GUIfrom Dannyvandenheuvel. I think that the current platforms I'm using are not the ideal ones to develop a community project. You are about to report the project "Thor", please tell us the reason. It is now possible to leave this part connected to the lower base and add the upper body separately. Add 1by1 clip Lego on the slant 2by1. Robot extensions can be customized to your manufacturing requirements. Quantity. Some things that I have though about but not in the short-term: Finally, this is the current look of the graphical part of Asgard: I'll be posting logs as the development reach the different versions. The brackets and supports for the arm are constructed from black anodized aluminum which makes for a strong support. On the left of the left fan hole (and on the right of the right hole) the wall is too thin. It's also recommended to weld a wire extension to the steppers wires, specially for the last three ones. If you want to include the home sensors, you will need to make the PCBs and weld the components. In this way, access to knowledge can be guaranteed to anyone, anywhere, without any economic cost. Any idea what it might be now? Thank you Olaf. If they are too long then Ihave to change the mounts between the upper and lower body. and last updated 4 years ago. It is possible to remove or add a M5 spacers (two steps up) to change the gap between the gears.
