Building a home robot: Part 5 - arms and hands

(see all parts of "building a home robot")

I wanted Roobert to get two identical hands with separate moveable fingers.

Because of this (and the small size) I decided to use a commercial construction kit instead of designing and constructing the hands on my own.

Although it was a construction kit it was fun for hours to assemble the hands:

Each arm is constructed from the hand construction kit, 3 servos, 3d printed servo brackets and an I2C servo controller. Because the servo controller seemed to be unable to shut down the servo power, I attached a relays for each arm to turn the servo power on/on.

The servo holder for the upper arm parts are printed in 3D:

The complete arms:

The right arm:
