The invention relates to a throwable deformable micro- robot. The micro-robot comprises a main mounting frame, a camera mechanism which is arranged on the top of the main mounting frame, two sliding blocks which are symmetrically arranged at two sides of the main mounting frame and used for realizing the deformation of the robot, a driving mechanism comprising a motor and a rechargeable battery, and a shell mechanism, wherein, the main mounting frame is equipped with a guide rail and elastic components in a horizontal direction; the sliding blocks are sheathed on the guide rail and connected with the elastic components, and the sliding blocks are equipped with wheel axles in the horizontal direction; a blocking mechanism is arranged at one end of each wheel axle and connected with the main mounting frame in a fit mode, and the other end of each wheel axle is fixedly connected with the shell mechanism; and the shell mechanism comprises a semispherical shell and a buffer shell which is bonded on the semispherical shell. The robot has the advantages that the structural layout is optimized, the structural strength is improved and the volume is reduced, in addition, by adding the buffer shell made of a flexible material, the shock resistance is greatly enhanced without affecting the grab of a user on the robot.
