The magnetic ball is held in the air with an electromagnet in the upper part of the arm.The loop is closed by a Hall sensor, which determines the position of the ball based on its magnetic field, and transmits the position information by radio to the controller in the upper part of the arm. For Transmitter and receiver the transceiver developed by IAS is used.
