Motor controls

• A. Have power routed from the power source and are connected to the microcontroller with PWM cables
• B. Are wireless subsystems
• C. Produce power to the motors
• D. Are the only components in the drivetrain

Answer: (A)

Motor controls regulate the power delivered to the drive motors. They take control signals from the robot’s microcontroller, typically via PWM connections, and use those signals to adjust how much power reaches each motor. The power itself comes from the robot’s power source and is routed through the motor controllers to the motors. They are not wireless subsystems, they do not generate power, and they aren’t the only components in the drivetrain. So the statement that motor controls have power routed from the power source and are connected to the microcontroller with PWM cables best describes their role.
