Internet-based teleoperation: A case study - toward delay approximation and speed limit module

This paper presents the internet-based remote control of mobile robot. To face unpredictable Internet delays and possible connection rupture, a direct teleoperation architecture with “Speed Limit Module” (SLM) and “Delay Approximator” (DA) is proposed. This direct control architecture guarantees the path error of the robot motion is restricted within the path error tolerance of the application. Experiment results show the effectiveness and applicability of this direct internet control architecture in the real internet environment.
