3D Stereoscopic Display in the Event-Based Real-Time Internet-Based Robotic Teleoperation System

In traditional teleoperation systems, the single video feedback provided to an operator generally suffers from a lack of spatial depth information. In this paper, we propose to provide real-time 3D stereoscopic visual feedback for the operator, so that they can accurately acquire information about the working environment with a sense of depth. However, due to the randomness of the Internet delay, the received video tends to be stuck or interrupted, which makes the operator manipulate without obtaining the information of the remote operating environment. In this paper, an event-based robot teleoperation system is designed and constructed to ensure the synchronization of control commands and feedback events. Experiments have been conducted to reveal that the use of real-time 3D stereoscopic video feedback in the event-based robotic teleoperation system can enable operators to perform tasks more safely, accurately, and efficiently.
