LEGO 9842 NXT Interactive Servo Motor

In order for the robot to measure speed and distance and transmit data to the NXT unit, you will need this interactive servomotor with a built-in rotation speed sensor. This sensor allows the engine to control the rotation of the shaft with an accuracy of one degree. You can set the servos to run at the same speed. To operate, you need a connecting cable from the NXT Basic Set. Age: 8+
