Title:  NEGATIVEPRESSURE SUCTION SELFPROPELLED ROBOT DEVICE 
Abstract: 
A robot device that is can attach the surface of an object by negativepressure suction, can move in a Yaxis direction and an Xaxis direction, and is equipped with four sucker units, Yaxis actuators and Xaxis actuators. The planar shape of the suckers forms one square divided into four quadrangles each having the same shape. The quadrangles are formed provided with two rightangle portions in a diagonal portion. One right angle of the two rightangle portions forms one of the four right angles of the square. Two of the sides that form a right angle of the sucker overlap with two of the edges that form a right angle of the square. One set of sides among two of the sides that form the other right angle of the sucker and two of the sides that form a right angle of the square intersect at an acute angle and the other set of sides intersect at an obtuse angle.
