Robot Arm Integrator
Servo bus driver for the SO-ARM100 and SO-ARM101 robot arms
Description
Drives a six-axis SO-ARM100 or SO-ARM101 arm built from Feetech STS3215 smart servos. The servos daisy-chain on one half-duplex UART bus, so the whole arm needs a single port and one cable: the module carries the bus data line and feeds the servos from the board's 12V rail through a 3A fuse. Move the arm by hand, record the motion and play it back.
