1. A robot adapted to movement on a surface of a plate, the robot comprising:

  • a body;

    at least one traveling device, which is disposed in the body for causing the robot to move on the surface of the plate;

    a suction cup, a part of the suction cup being movably disposed in the body; and

    a pump module disposed in the body, whereinthe suction cup can move relative to the body in a direction along a normal of a bottom surface of the suction cup, and upon an operation of the robot, the body, the suction cup and the plate form a closed space, wherein the closed space is kept at a negative pressure by use of the pump module; and

    an area of a first region of a space defined by the suction cup is substantially larger than or equal to an area of a second region of a space defined by the body,an acting force is caused by the negative pressure of the closed space,a first acting force of the acting force is substantially caused by the negative pressure in a residual region and distributed on the suction cup, wherein the residual region is the region of the first region outside the second region,a second acting force of the acting force is substantially caused by the negative pressure in the second region and distributed on the at least one traveling device.
