    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

    Robin Fröjd • 4 days ago • 0 comments

    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 Fröjd • 5 days ago • 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? 

  • Camera cover

    Robin Fröjd • 6 days ago • 0 comments

    Tonight's work: camera cover for the #realsense #d455 also added a few air ducts. Still in progress! :)

  • 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

    Robin Fröjd • 01/07/2021 at 17:24 • 0 comments

    Jumping between different parts of this Project. Last Days I have been working with covers. Adding a rail-system integrated in top cover, also added a small section for different outlets.

    1. 1 x XT90 external battery port
    2. 2 x XT30
    3. USB
    4. HDMI.

    Tomorrow the first leg parts will probably arrive! :-)

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!

  Are you sure? yes | no

Robin Fröjd wrote 12/28/2020 at 12:04 • point

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