方法的有效性，为今后实际空间机器人的地面遥操作提供了经验．-The ground teleoperation platform of satellite on-orbit self-serving system is construe—

ted in the background of space robot on-orbit serving．W hen a malfunction of the satellite occurs，

the teleoperator uses a space mouse and a data—glove with force feedback to control the arm／hand

system fixed on the satellite body to remove the malfunction to implement the satellite selfserving．

For the large time delay of the communication between ground and space，3D graphic

predictive simulation is employed to eliminate the impact of the time delay，and the virtual fixture

is utilized tO improve the performance and safety of the telemanipulation． Under the condition of

large and variable time delay(about 7 s)，the task of deploying a folded solar panel，a typical onorbit

serving of the satellite，is accomplished by operators in W uhan through teleoperating the

four-degree freedom robot arm／hand system in Harbin．The experimental results show the effec—
