To efficiently perform work using a remote-controlled robot, an image display device that allows the operator to verify the working area from a single view is necessary. Furthermore, this device should provide high-resolution images of locations so that the operator can recognize depths in detail. To meet these requirements, conventional three-dimensional image devices used multiple cameras and display screens for the right and left eye. In this study, we developed a video device that employs a camera and a display, which records a wide range while providing high resolution for the central part of the images using a mirror. The effectiveness of our device was confirmed through an evaluation experiment using a remote-controlled work robot. The results indicated that using the transmitted complex display, the operator can utilize high-precision space information and respond to a wide range of changes in the surrounding environment. It was thus confirmed that the remote-controlled operation could be conducted with improved accuracy and in a shorter time.

“…When a subject actually works in the real work spot, force, tactile, and acoustic senses are also used besides vision. In the conventional type of teleoperated robots, the lack of sense information except vision may be the reason for the inefficient cognition of working space 6,7) . There were some studies which tried to improve the performance of the teleoperation by providing sense information which subjects usually use in a real working spot 8,9,10) .…”

It has been reported that the operation efficiency during teleoperation under stereoscopic video images is inferior to that of using the naked eye on the spot in real working environments. One of the reasons to explain this might be the smaller amount of information which is provided to the subject when working under stereoscopic images compared with that gotten by direct viewing in the real working environment. In our daily lives, we obtain information through various senses; the visual sense, acoustical sense, tactile sense and so on. The smaller amount of information causes a low working performance in the teleoperation. Some papers showed the improvement of operation efficiency when the subject got acoustic and/or tactile feedback as well as visual feedback in a simulated environment. We investigated to clarify the effects of force and acoustic feedback information with stereoscopic video images to subjects on the performance of the teleoperation using an actual robot. In experiment 1, we used the teleoperated system in which subjects could control the robot arm (the slave manipulator) to pick up cylindrical objects and to insert them in a hole by operating the input-and-tactile-information-display-system (the master manipulator). The results of experiment 1 showed that the force and acoustic information did not improve the working performance, and rather interfered with it. In experiment 2, we investigated the operation efficiency under conditions that force or acoustic feedback was given in the teleoperated work by eliminating contact information acquirable from vision. As a result of the experiment, force and acoustic information was not an effective way to shorten the completion time when the actual teleoperated robot was used.

Teleoperation requires both wide vision to recognize a whole workspace and fine vision to recognize the precise structure of objects which an operator wants to see. In order to achieve high operational efficiency in teleoperation, we have developed the Q stereoscopic video system which is constructed of four sets of video cameras and monitors. It requires four video channels to transmit video signals. However, four channels are not always available for a video system because of the limitation of the number of radio channels when multiple systems are used at the same time. Therefore we have tried to reduce the number of channels on this system by sending images from the right and left cameras alternately by field. In experiment 1, we compared the acuity of depth perception under three kinds of stereoscopic video systems, the original Q stereoscopic video system, the Q stereoscopic video system with two channel transmission, and the conventional stereoscopic video system. As the result of the experiment, the original Q stereoscopic video system enabled us to perceive depth most precisely, the Q stereoscopic video system with two channel transmission less so, and the conventional stereoscopic video system even less. In experiment 2, we compared the Q stereoscopic video system with two channel transmission to the original Q stereoscopic video system. The result showed that the operators were able to work more efficiently under the original Q stereoscopic video system than under the Q stereoscopic video system with two channel transmissions. In experiment 3, we compared the Q stereoscopic video system with two channel transmission to the conventional stereoscopic video system. It was found out in this study that the new stereoscopic video system we developed enabled operators to work more efficiently and to perceive depth more precisely than the conventional stereoscopic video system, although the number of channels for image transmission of this system was equal to that of the conventional stereoscopic video system.
