Made a larger center box to accommodate a raspberry pi with a robot hat. Made an adapted housing for the ultrasonic sensor. Made some distancers to reduce the use of metal nuts. Made a lid for the box with room for a pan and tilt camera (like this one: https://www.thingiverse.com/thing:708819).
Feet got adapted to fit some rubbers in it (with superglue), so the beest has a grip on a hard flooring.
Adapted part of the gear housing to place some neopixel leds.
