Abstract

Integrated Services Digital Network (ISDN) communication technology has made it possible to conduct broadband teleconferencing and teleoperation in a method which is much less costly than satellite systems. Fujita Research has taken advantage of this medium to conduct teleoperation tests of a robot system across the Pacific Ocean. Through our application, researchers in Encino, California were able to conduct simple pick and place tasks using a 6 degree-of-freedom robot in Tokyo, Japan. Problems of time delay and low update rates prompted preliminary investigations on the use of visual enhancements. The use of predictive overlays and stereo visual cues were investigated using the ISDN set-up and results confirm past studies which indicate their usefulness in improving teleoperation task performances. This research may eventually be applied to remote monitoring and operation systems of robots on several construction sites or in hazardous environments.
