Description

technical field [0001] The invention relates to a device and a method for ground three-dimensional space microgravity, in particular to a device and method for simulating the ground three-dimensional space microgravity in which a space manipulator captures a target satellite. Background technique [0002] Since the space manipulator operates in space approaching and capturing target satellites, its satellite base is usually uncontrolled and in a free-floating state. In space, the space robot system is in a microgravity environment, and the influence of the earth's gravity is usually not considered. Therefore, the space robot system satisfies the law of conservation of momentum. When the space robotic arm moves, its floating satellite base usually produces corresponding disturbances. At present, the test of the space manipulator is usually carried out on a two-dimensional air-floating platform, which usually does not consider the movement of the base of the floating satellit...
