Patent number: 11045059Abstract: A self-propelled robot autonomously travels on a structure having a target plane and performs work on the plane of the structure. The robot includes a robot main body provided with a moving means for autonomous traveling, a control unit that controls movement of the robot main body, and a working unit that performs work on the target plane. The control unit includes an edge detection unit that detects an edge of the target plane, and the edge detection unit includes an outer detection unit located outward from the working unit in the traveling direction of the robot main body and an inner detection unit located closer to the robot main body than the outer detection unit in the traveling direction of the robot main body.Type: GrantFiled: March 31, 2017Date of Patent: June 29, 2021Assignee: Miraikikai, Inc.Inventors: Kazuo Morita, Tohru Miyake

Patent number: 10391637Abstract: Provided is a self-propelled robot that can prevent damage due to dropping of the self-propelled robot and efficiently perform the operation on a flat surface. A self-propelled robot 1 that self-travels on a structure SP having a flat surface SF to perform operation on the flat surface SF of the structure SP, the self-propelled robot includes: a robot main body 2 in which a moving unit 4 for the self-travel is provided; and a controller 30 that controls movement of the robot main body 2. At this point, the controller 30 includes an edge detector 31 that detects an end edge of the flat surface SF, and the controller 30 has a function of controlling activation of the moving unit 4 such that a distance between the end edge of the flat surface SF and the moving unit 4 is maintained to a given extent or more based on a signal from the edge detector 31.Type: GrantFiled: June 25, 2015Date of Patent: August 27, 2019Assignee: MIRAIKIKAI, INC.Inventors: Tohru Miyake, Kazuo Morita, Hideto Matsuuchi

Patent number: 10020774Abstract: Provided is a self-propelled cleaning robot that can efficiently perform cleaning even on a flat surface having a gap or a step. A self-propelled cleaning robot (1) that self-travels on and cleans a flat surface (SF) of a structure, a groove (G) being formed in the flat surface (SF), the self-propelled cleaning robot (1) includes a robot main body (2) in which a self-propelled moving means (4) is provided and a guidance unit (40) that guides movement of the robot main body (2). At this point, the guidance unit (40) includes: a shaft member (43) that is provided so as to be detachably inserted in the groove (G) and a shaft member moving mechanism (45) that controls insertion and removal of the shaft member (43) with respect to the groove (G). The robot main body (2) is provided so as to be turnable about the shaft member (43) in a state in which the shaft member (43) of the guidance unit (40) is inserted in the groove.Type: GrantFiled: December 25, 2013Date of Patent: July 10, 2018Assignee: MIRAIKIKAI, INC.Inventors: Kazuo Morita, Tohru Miyake
