Abstract

To appropriately recover a mobile robot in which an abnormality has occurred. A control device for a mobile robot is provided with: at least four wheels arranged on the front, rear, left, and right; and motors that drive each of the wheels. The control device is provided with: an abnormality detecting unit that detects abnormalities in each of the motors; an arrangement position changing unit thatchanges an arrangement position of the wheels corresponding to the motors in which an abnormality has not been detected, when the abnormality detecting unit has detected abnormalities in the motors corresponding to all the wheels on either the left or the right; and a travel control unit that drive-controls the motors in which an abnormality has not been detected to cause the mobile robot to travel to a prescribed target position.

Description

technical field [0001] The invention relates to a control device of a mobile robot and a mobile robot system. Background technique [0002] In recent years, automation has been promoted in factories and the like, and mobile robots such as unmanned delivery vehicles have been adopted for the transportation of goods. In the past, when an unmanned delivery vehicle was unable to run due to some abnormality, it was necessary to send workers to the scene in order to recover the stopped unmanned delivery vehicle. [0003] Therefore, Patent Document 1 discloses that the stopped unmanned guided vehicle is towed by another unmanned guided vehicle (rescue vehicle) in order to quickly avoid the stopped unmanned guided vehicle from the traveling road. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Application Laid-Open No. 11-5520 Contents of the invention [0007] The problem to be solved by the invention [0008] However, in t...
