• It now has a head! (Kinda.)

    In the past, I’ve created a variant of this robot head project: https://hackaday.io/project/185066-robot-buddy. Instead of using an LED matrix, it uses an old phone as the display.

    So I've added it to this robot.

    (I plan to open-source the “face” app, but it needs a lot of cleanup first.)

    The potentiometers are attached in the same orientation as the arm’s axes.

    This will be difficult to control in a human-friendly way, so I’m experimenting with ADS115 modules (analog to I2C input) to see if I can build a puppet-style remote using potentiometers to control the arms.

    I'm very impressed by how well the 80/60kg servos are handling this weight. I was honestly expecting some kind of horrible motion—either super slow or really wobbly—but it actually moves pretty well!

    (Yes, it's an old monitor stand)

  • One arm at a time

    I was afraid that the 80 kg servo wouldn't be enough for the shoulder to support the weight of the arm, but it's surprisingly okay with it.

    First version of the design, with a 5-DOF per arm setup (2×80 kg, 2×60 kg, 1×20 kg servos).

    I’ll start building around those 80/60 kg servo motors, since I have some salvaged from other projects, and I don’t want to begin by buying expensive brushless motors for a first attempt.
