Thread: uArmⅠ:An open source robot arm Project

    Re: uArmⅠ:An open source robot arm Project

    After a few days of improvement work, we have made some new designs of the robot arm. Make some changes of the structure to make the arm stable. Add a small gripper and the new sucker holder. Then we decide to try some other materials to make the robot arm. So we got a laser cut Basswood one.


    Here is the laser cut Basswood parts.



    Do the assembling.



    The finish Basswood uArm.



    More details of this arm.



    Here the small gripper and the new sucker holder.



    Change the head of the arm and install the gripper on the arm.









    What’s more, we also made a transparent one by acrylic this time.



    Here is the way that you can install the sucker with the new holder on the robot arm.



    So far, we have 3 uArmⅠ, the black acrylic one, the basswood one and the transparent acrylic one.



    More testing videos and improvements will be updated soon. We are going to make this arm better, more stable and more accurate.

    Cool! I really dig the picture with all of them next to one another. You got yourself your own pick and place production line.

    Next, you can have them assemble their own brothers! Would that be possible?

    The second version of the robot arm is quite stable now. Here is a stacking test by using the gripper. More applications and test videos will be updated soon.

    A Vacuum Gripper Suction Cup is often used on industry robot arm in manufacture. And we also add a small one on uArm.

    The Vacuum Gripper Suction Cup is controlled by a small Vacuum Pump and a Solenoid Valve.


    We made the first load test of the robot arm by using the Vacuum Gripper Suction Cup. It can lift a 330ml Coca Cola and move it to another place. More applications and test videos with the Vacuum Gripper Suction Cup will be updated soon.

    After several tests of the arm with vacuum gripper suction cup, the robot arm can work very well.


    Recently, we got an Iphone 5S, so we decide to make an unboxing test of Iphnoe 5S by uArm.



    Let’s see how it works.



    More interesting applications and test video of uArm will be updated soon.

    Don't know if you guys saw it, but that iPhone unboxing video made the Make Magazine blog: http://makezine.com/blog/

    This is a great project! Very well done. I played around with some suckers for some R&D we did a loooong time ago. One thing I never figured out was how to let go of objects. I couldn't find any good low cost valves that would exhaust the suction and just attaching the pump direct created constant suction that never let go. How did you solve it?
