• A walker needs legs!

    Finally, the bottom part of my biped named Walk-R is now done.  After countless redesign and re-prints, here it goes!

    I will now spend my time researching how best to make it alive.

    The next steps:

    1. Integrating the MPU-6050 to the RPI4.
    2. Doing balancing tests
    3. Doing simulations in ROS Gazebo to study possible algorithms for balancing.

    That's it!

    Stay tuned!

    I finally got sick of battling with the XL-320, OpenCM and  Pixl boards.  It was either not working under Linux or not working with more than 6 servos.

    So, I looked up for something else and after a while, my choice stopped on the LewanSoul servos.  So far, they meet my expectations.  I have 1 leg done (minus the foot, which requires a redesign) and I'm waiting for the next batch of servos to come at my door.

    Stay tuned, as I will show up where I'm at when the second leg (and hips) is done!

    I've begun to port the thing from the OpenCM to the Raspberry Pi, using the Pixl board.

    I still have issues with it, though.  Next post should be when I have solved those issues and have a robot standing on its own two legs!

    Next goal: A self-balancing biped bot...
