    Gripper planning, I think a flex joint is needed which lets the gripper go up when on the ground. 

    Each claw is planned for be double jointed. The most suited micro linear actuators I could find was the LASF16-104D. Which also provides force feedback. 

    They have the follow specs:

    K3lso wants to stand out from the dog herd!

    Check it out and give me your comments! 

    And yes I am planning for a Jaw gripper. :-)

    So. I have ordered two kits from Luxonis  the DepthAI: USB3C with Modular Cameras. Which I will test.

    I also have adjust the side cover to fit the cameras in a nice way (Removing the "spot" look) 

    The camera covers can be removed  with the USB3C and the modular cameras. One of the main reasons I took this path, is quite simple. I can more easily integrate these into the covers. Changing lenses and adjusting the baseline is also better. 

    We will see how they work out! :)

    so last days I haven't done much. Cleaning up k3lsos workbench and added a monitor 

    I have also been working to finalize the mid covers. I would say I am about 90% done with the mid-covers. I will continue to work on them tonight

    So I think it's decided. I don't know why I didn't think about it before. Since this build is named after my deceased pug. This is the color it should have! 

  • Stand is 90% done

    So I just got the parts for the robot stand today. Printed some mounts that wraps around the hip actuators. Which means I can just lift it on the stand and it sits there VERY firmly.

    Perfect. Now it will be a bit easier to work on it :)

  • Black or Green?

    Robin Fröjd01/12/2021 at 00:19 2 comments

    having hard time deciding on the final color scheme. They both looks good and both have +-  

    We shall see. What do you guys think?

  • More assembly testing

    awaiting parts for the robot stand. Its a bit hard to move this around as it is. So in meanwhile I am just doing some more assembly testing

Impressive work. Is this a commercial endeavour, is it open source? I can't even imagine how many hours of design and CAD work this took. Following!

At the moment only for fun :) But I guess it will be open source in the end. ;) Thanks!
