for my robotics project I am looking for a simple and elegant way to control 4 Dynamixel servos (2x XL430, 2x XL330) and 3 stepper motors (1x bipolar, 2x unipolar). The two unipolar motors, I would like to operate bipolar to exploit their maximum torque. As control unit I would like to use a Raspberry Pi.
I am having a hard time choosing suitable stepper motor drivers. The stepper motors are the following:
- bipolar: ST4118D1804-A - Schrittmotor – NEMA 17 |…
- unipolar: https://de.nanotec.com/produkte/369-st4118l1206-a
For the control of the Dynamixel servos, the OpenCM9.04-A controller board has already been recommended to me. Do you agree with this? What are the tasks of this controller board?
How do I connect all the elements?
