5 Teleoperation of a Mobile Robot by Telepresence with an Omnidirectional Sensor 3 Misato Yoneda Abstract Recently research of telepresence which improves the ecientry of teleoperating remote robots is getting popular A stereoscopic camera realizes telepresence for teleoperation However when an operator looks around there is time delay in acquisition of an image in that direction In this paper a new method to realize a telepresence for teleoperation without such time delay is proposed In this method an omnidirectional image sensor is placed on a mobile robot in order to present monocular images when the robot is moving and present binocular stereo images generated from a sequence of omnidirectional images when the robot stands still Using the proposed method a user can look around the scene with depth perception without signicant time delay. A teleoperation system based on the proposal method is built for proving the feasibility In the system ultlasonic sensors are also used to avoid obstacles and an arrow is superimposed on the real scene image around the robot to indicate the moving direction Experiments have been carried out in an indoor environment forevaluating the proposed method Keywords: mobile robot teleoperation telepresence omnidirectional image sensor binocular stereo HyperOmni Vision 3 Master's Thesis, Department of Information Systems, Graduate School of Information Science, Nara Institute of Science and Technology, NAIST-IS-MT , February 9, iii
