This paper summarizes salient activities within the NASA Telerobotics Program, emphasizing complete telerobotic system prototypes which have been built and tested in realistic scenarios relevant to prospective users. The paper also describes complementary developments in innovative component technologies.

This paper discusses the safety assurance, capability features, and user-friendliness of Internet-based telerobotics, in the sense that how these features could be incorporated in order to enhance teleoperator performance. A comprehensive set of safety features are incorporated to the interface to screen and accept only the safe commands from the remote operator while discarding risky commands....

We are investigating a field of research that we call ubiquitous telepresence, which involves the design and implementation of low-cost robotic devices that can be programmed and operated from anywhere on the Internet. These devices, which we call ubots, can be used for academic purposes (e.g., a biologist could remote conduct a population survey), commercial purposes (e.g., a house could be sh...

A promising way to achieve increased remote worksystem efficiency is to layer telerobotic technologies onto teleoperated remote systems. The research being reported here will enable the teleoperation baseline to be supplemented with operatorselective telerobotic modes of operation that allow automatic performance of subtasks that are either repetitive, require high precision, or involve extreme...

This paper concentrates on transparency and synchronization of supermedia in Internet based teleoperation. Supermedia is used to describe the collection of all the feedback streams in teleoperations, such as haptic, video, audio, temperature and others. Transparency and synchronization are introduced and analyzed from the event-based control perspective. The concepts of event-transparency and e...

In this paper we present the performance evaluation of a Distributed Component based Telerobotic Framework that implements a real-time interaction between a telrobotic client and server. The objective is to optimize delays in multistreaming of force feedback, stereo data and master-slave commands. Different scenarios are considered and statistically analyzed to relate the effect of thread manip...
