ABSTRACT:
An improved tactile feedback device for a remote control robot using a repulsive force of a magnet, which is capable of achieving a more accurate operation and productive work of the robot by transmitting the tactile information of a work object positioned between grippers of robot hands to a robot operator in a central control room, which includes a computer for receiving a tactile information and for outputting a tactile feedback signal in accordance with the tactile information; a driving circuit unit for converting a tactile feedback signal outputted from the computer into a current; and a tactile feedback device for transferring a predetermined pressure to an operator in cooperation with a repulsive force between an electromagnet and a permanent magnet when the electromagnet is driven in accordance with a current applied thereto from the tactile feedback device driving unit.
