I’ve combed through the forums and it seems that either a RoboClaw 2x30A Motor Controller or a Sabertooth dual 32A will work with my Pixhawk 4 running Rover 3.5. Aside from price it seems the Roboclaw has integrated decoders, hence off-the-shelf closed loop control, while the Sabertooth requires the Kangaroo x2 motion controller if I decide I need the controller to do the closed loop control. I’m planning on building encoders on the motor shafts directly (shafts turn 3600rpm). My thinking is to build and run without closed loop control, then, start by feeding encoder data directly to Rover (which I understand it will use in position estimation if I’m running EKF3).
Aside from price, does anyone know of any pluses or minuses or considerations I should be aware of when choosing the motor controller? Any experience with cheap no-name brands?
Thanks in advance…
