ABSTRACT:
A tactile feedback apparatus using an electromagnetic attraction for a remote control robot employs tactile data obtained during operation between a gripper attached to a robot arm of an externally controlled robot and the gripper's target so as to be transferred to an operator stationed in a central control room, thereby enabling the robot system to effectively carry out sophisticated tasks. The tactile feedback apparatus enables a successive tactile control by use of an electromagnetic attraction, and an array type fabrication, and by optimizing a production design to broaden a tactile feedback area, there may be provided a small tactile feedback device for representing a relatively improved tactility per unit, and further by aligning the tactile feedback devices in a 5.times.5 array mode on a skin of 15.times.15 mm.sup.2, there is obtained a contact location thereof.
