Spatial cell robot

The invention relates to a robot, in particular to a spatial cell robot. The spatial cell robot solves the problems that an existing spatial robot is large in size, poor in reconfigurability, low in rigidity, poor in maneuvering capacity and narrow in operating range, and does not meet the operating requirement under the space zero-gravity environment. The spatial cell robot comprises a main structure, a mechanical arm and a tail end grasping docking mechanism. The main structure comprises a rotating block, a connecting rod, a clamping mechanism, a rolling mechanism, two main discs, two docking plates and two fixing blocks. The clamping mechanism comprises a first lead screw, a first servo motor, two sliding blocks and two clamping modules. The rolling mechanism comprises a second servo motor, a driving belt, a connecting shaft and a roller. The tail end grasping docking mechanism comprises a third servo motor, a third lead screw, a movable rod, an interface board and two gripper jaws. The two main discs are connected through the connecting rod and connected with the docking plates through the fixing blocks. The spatial cell robot is used for docking grasping of objects in aerospace.
