Abstract
This paper proposes the robot remote operation using a force constraints based on the data transmission signal level. A mobile robot is controlled by a haptic device through wireless LAN. First, the three stages signal level is set reaction force to return increases as the signal level is low. Secondly, we evaluate a range of signal level in the experimental environment. Lastly, the robot is operated without the reaction force and using the reaction force. The experiment proves the validity of robot remote operation using a force constraint based on the signal level.
