In this paper we propose a strictly conservative and novel hybrid safety control strategy consisting of the pre-contact safety strategy and the post-contact safety strategy in order to provide safety guarantees and enable continuous motions. An optimal motion trajectory planning that limits jerk, acceleration and velocity of robot motion and can obtain a time optimal motion is introduced as post-contact...
This paper developed a teleoperation system of a space robot, which can assist the operator in planning trajectory quickly and intuitively. In addition to the general function, this system can ensure the completion of certain mission when some joint of the space robot is locked for a hardware malfunction. The teleoperation system includes 4 subsystems-Graphics display subsystem, Camera monitor subsystem,...
A key technology of space robots is to maintain the satellite attitude while space service is proceeding. This paper discusses the motion planning and control methods for both robot satellite attitude and robotic end-effector actions in the form of collaboration. A single gimbal control moment gyro (SGCMG) system is adopted to maintain the satellite attitude because of higher output torque than traditional...
