Abstract: Recently some-noticeable efforts have been devoted to the internet-based MOMR(multi- operator-multi-robot) collaboration. MOMR teleoperation would have a significant advantages over SOSR(snigle-operator-single-robot) in group work such as the plant maintenance, construction, and surgery. Control of MOMR teleoperation system plays an important role in remote operations in dangerous or difficult-to-access environment. This paper describes architecture and conception of internet-based MOMR teleoperation system and overviews the present situation, and its main problems and-various coordinated schemes are also discussed.
