Re: Motor Speed Controllers
There are physical motor speed controllers, such as Victors and Jaguars, which adjust the voltage applied to the motor in response to software commands.
If you need more precise speed control (closed-loop), you would need a sensor which measures speed (such as an encoder, or if the speed is high enough a high-speed light sensor and code wheel on the shaft/wheel to be measured), and either code on the robot to control the speed or a Jaguar which internally does closed-loop control, but requires the CAN bus.
