Document Type and Number:
WIPO Patent Application WO/2020/137499
Kind Code:
A1
Abstract:
[Problem] To provide a robot device that can adhere to an object surface by vacuum suction and move autonomously in either of a Y direction and an X direction. [Solution] A robot device 4 is provided with four suction pad units, a Y-axis actuator, and an X-axis actuator. The planar shape of a suction pad is the shape of one square quartered into four quadrilaterals having identical shapes. Each of the quadrilaterals has two right-angle portions formed at diagonally opposite corners, and one right angle of the two right-angle portions forms one right angle of the four right angles of the square shape. The two sides forming the one right angle of the suction pad overlap the two sides forming the right angle of the square. The two sides forming the other one of the right angles of the suction pad intersect the two sides forming the right angle of the square such that one pair of the sides intersect at an acute angle and another pair of the sides intersect at an obtuse angle.
