We propose a method to transmit electric power wirelessly from a two dimensional communication sheet (2DC sheet) to a robot, to control the behavior of the robot. This robot consist of 2 antennas, a DC motor and 4 rectification circuits. The two antennas allow users to control the robot's movement by changing the amount of power supplied to the robot. We have also developed a card containing aluminum sheet, to control the amount of power received by the robot. When the robot stands on the aluminum sheet, the power received by the robot can be cut off. As our system does not require to mount any battery and sensor on the robot, the size and weight of the robot can be relatively small and light.
