The invention relates to the field of robots and discloses a magic cube robot manipulator. The magic cube robot manipulator comprises supporting tables, clamping devices and driving devices. The clamping devices are oppositely arranged on the two supporting tables, each clamping device comprises a pneumatic finger and two clamping pieces, the two clamping pieces are oppositely and detachably arranged on two clamping jaws of the pneumatic finger respectively, and a clamping area used for clamping a magic cube is formed between the two adjacent clamping pieces. The driving devices are used for driving the corresponding clamping devices to rotate. The clamping distance of the clamping areas is kept equal to the side length corresponding to the magic cube. The clamping parts of the magic cuberobot manipulator adopt the pneumatic fingers, the clamping force provided by the pneumatic fingers is larger than that of a steering engine, the contact area between the claws of the pneumatic fingers and the magic cube is larger, and shaking of the magic cube in the clamping process can be reduced, so that the magic cube is clamped more stably.
