Design teleoperation for a quadruped robot with an arm

Design the system that lets a remote operator drive a four-legged robot carrying a 4-axis arm. The robot has three cameras: one on the body, one on the wrist and one on a pole above it. Cover how the operator's commands reach the robot and how video and state come back, and walk through the trade-offs you make along the way. Follow-up: if you could keep only one of the three cameras, which would it be, and why?
