Building a bot with many servos run by will Lynxmotion SSC-32U USB Servo Controller. Bot will have a 4 mecanum wheel drive system. Will the will Lynxmotion SSC-32U USB Servo Controller also control the motors or is a separate motor controller necessary?

The SSC-32U RC servo controller controls devices (like RC servos) using RC PWM pulses. You can select DC motor controllers which accept RC PWM input for controlling speed and direction, which you can plug into the SSC-32U, as you would an RC servo. You would only be able to use the SSC-32U to control the motors connected to the mecanum wheels if they are continuous rotation servos as opposed to DC gear motors, though this is unlikely unless your robot is pretty small (tabletop). Assuming you will use DC gear motors, you may also be considering encoders, which will need to be connected separately to a microcontroller. To summarize:
SSC-32U
-> RC servos (standard or continuous rotation)
-> DC motor controller with RC PWM input
Microcontroller
-> Encoders
-> SSC-32U for sending position commands

Hi @cbenson
wouldn’t it make sense to add an extension socket to the next SSC32 which fits a standard stepper driver or a dual H-bridge (pololu-compatible)?

Interesting idea to make it more of a “do all” type product. The current focus for development is on the Lynxmotion Smart Servos / Servo Erector Set V2 system, as well as other R&D projects. We do compile a list of all issues and suggestions, so yours is appreciated and will certainly be added, but not known yet if / when it can be implemented.
