Motors are devices that use electrical power to create mechanical rotation. With a LEGO motor, an axle can be inserted in the motor to make use of the revolution to, for example, spin the wheels of a robot or vehicle. But the motors have extra functionality: as servo motors, they are capable of precisely moving to a specific angle using a sensor inside the motor that monitors its angle and speed. The Hub uses the sensor embedded into the motor to allow setting the angular position of the motor’s rotation or set the motor’s speed. The exercises ...
