Raspberry Pi with Arduino - Raspberry Pi Forums

hi all,

have robotic arm project. arm has 6 motors, of 6th gripper motor. since pi has 1 pwm pin, want use arduino board generate respective pwm signals needed motors. want algorithm(inverse kinematics , forward kinematics) computed pi....send relevant signals arduino generate 6 pwm signals.

possible???........help.....

note encoder output each motors read pi.......

first pick method pi use communicate arduino (usb or serial better options).
pick format output data.
determine transmission failure criteria.
write arduino sketch generate pwm signals based on signals pi output.
