Dum-E

For perception, Dum-E uses a two-camera system split between the head and the base. A Pi Camera Module 3 mounted on the rover's body acts as a fixed, wide-angle "scout" camera — it stays stable while the robot drives, used for navigating the room and spotting objects from a distance without any of the shake or wiring complexity that comes with a camera that moves with the arm. A second camera sits on the arm's head, doubling as Dum-E's expressive "face" and serving as the close-range eye for fine positioning during a grab — once the base camera has spotted an object and the arm closes in, the head camera takes over to guide the final centimeters of approach. I already have a Raspberry Pi, just need omni wheels base, microphone, cameras, and small circuits.
