  • Publication number: 20190030731
    Abstract: A robotic device that can adhere to the surface of an object by negative-pressure suction and that can travel in a Y-axis direction and an X-axis direction. The robotic device is equipped with four suction cup units, Y-axis actuators and X-axis actuators. As for the planar shape of each suction cup, it has a shape of each quadrangle when a roughly square was divided into four quadrangles of the same shape. The quadrangles are formed provided with two right-angle portions in a diagonal portion. One right angle of the two right-angle portions of each suction cup overlaps with one of the four right angles of the square. Two of the sides that constitute the above right angle of the suction cup overlap with two of the edges that constitute the above right angle of the square.

  • Publication number: 20160363160
    Abstract: To provide a simple, lightweight, and low-cost device that is capable of adhering by suction to an object surface and moving therealong. This device is at least formed from a suctioning unit, horizontally reciprocating units, vertically reciprocating units, and double-acting leg members. As a first step for enabling the device to travel along an object surface, the double-acting leg members are strongly pressed against the object surface. As a second step, the suctioning unit is moved in the traveling direction of the device with the double-acting leg members strongly pressed against the object surface. As a third step, the double-acting leg members are separated from the object surface. As a fourth step, with the double-acting leg members separated from the object surface, the double-acting leg members are moved in the traveling direction of the device and returned to the state immediately prior to the first step. Thereafter, the actions of the first to fourth steps are repeated.

  • Publication number: 20120192897
    Abstract: PROBLEM TO BE SOLVED: To provide “working device for internal pipe and working method for the same” characterized in that the travelling force in pipe is very large. SOLUTION: The working device for internal pipe is equipped with an annular pressure boundary seal of which the free end part comes into contact with the wall of the pipe and the seal divides the internal space of the pipe into two spaces, that is, a space A and a space B using the seal as a boundary. One end part of the space A close to the seal is connected to a suction pump through a hose and also connected to the space B through a vacuum breaking valve mechanism for adjusting the negative pressure in the space A, while the other end part of the space A far from the seal is closed, and the hose is arranged in the space B.
