There are three Servo Motors included in the Mindstorm kit. Each motor has a built-in Rotation Sensor. This lets your control your robot’s movements precisely. The Rotation Sensor measures motor rotations in degrees or full rotations (accuracy of +/- one degree). One rotation is equal to 360 degrees, so if you set a motor to turn 180 degrees, its output shaft will make half a turn. The built-in Rotation Sensor in each motor also lets you set different speeds for your motors (by setting different power parameters in the software). The motors have sufficient power in order to make the robot balance. | There are three Servo Motors included in the Mindstorm kit. Each motor has a built-in Rotation Sensor.
