Internet‐based robotic systems for teleoperation

TLDR

Internet technology enables integrated network environments for diverse robotic applications, yet Internet‑based robots must possess high autonomy and local intelligence to cope with limited bandwidth and variable transmission delays. This work presents the initial step toward constructing an Internet‑based robotic teleoperation system at the University of Essex. The system employs a standard network protocol and an interactive web‑browser interface that allows a remote operator to navigate a mobile robot in a laboratory setting with visual feedback and a simulated map, facilitating intuitive remote task execution. Although in its early stage, the prototype demonstrates potential applicability to tele‑manufacturing, tele‑training, and tele‑service scenarios.

Abstract

Today’s Internet technology provides a convenient way for us to develop an integrated network environment for the diversified applications of different robotic systems. To be successful in real‐world applications, Internet‐based robots require a high degree of autonomy and local intelligence to deal with the restricted bandwidth and arbitrary transmission delay of the Internet. This paper describes the first step toward building such an Internet‐based robotic system for teleoperation in the University of Essex. The system has a standard network protocol and an interactive human‐machine interface. Using a Web browser, a remote operator can control the mobile robot to navigate in our laboratory with visual feedback and a simulated environment map via the Internet. The employment of an intuitive user interface enables Internet users to control the mobile robot and implement useful tasks remotely. Although at its first stage, the developed system has the potential to be extended to many real‐world applications such as tele‐manufacturing, tele‐training and tele‐service.
