As an effective environment representation method, the obstacle occupancy grid has been widely applied on the autonomous vehicle, providing evidence for the behavior decision and path planning of autonomous vehicle. In this paper, a new obstacle occupancy grid named space-time occupancy grid map is presented. This map pays more attention on the dynamic obstacles in a period of future time, and maps...
ITER (international thermonuclear experimental reactor) tractor is an in-cask remote handling equipment, and its tilting and lifting mechanism is very important for the tractor to operate 45t plug in front of the ports of the hot cell and the VV (vacuum vessel) successfully. This paper was aimed at proposing a tilting and lifting mechanism to accurately grasp and operate the heavy-load plug in the...
A suspension system for studying the dynamic characteristics of space robots working under microgravity condition is introduced. The system can apply a constant force against the gravity of an operating target. The support point on system's end-effector synchronously tracking the motion of suspension object is expected to obtain long-time zero-gravity of the target satellite. According to dynamic...
