Abstract

A door opening and closing robot includes: a door operating tool including an insertion and restricting portion; a robotic arm that moves the door operating tool; and a control device that: operates the robotic arm, wherein the door operating tool moves to a first reference position, then moves toward a first presence confirmation position; obtains a position of the door operating tool as a first evaluation position; and determines a deviation between the first presence confirmation position and the first evaluation position, when the deviation is less than or equal to a predetermined first threshold, detects failed presence of the insertion portion in a window groove. The first reference position is the operating tool which is inserted in the window groove and the restricting portion is in contact with an edge of the window groove or positioned above the edge of the window groove.
