Abstract
In this paper, we will describe the results of our truss structure tele-manipulation experiments on the ETS-7 (Engineering Test Satellite 7), that have been done from March 1998. The purpose of our experiment is to establish the basic tele-robotics technologies for on-orbit truss manipulation that was thought as rather sophisticated and also too small size for the current space robots, such as the space shuttle robot arm and the international space station robot arm.
