Abstract:
1. A robot apparatus comprising: a robot mechanism unit having a plurality of robot arms and a robot main body to which the robot arms are attached; an object recognizing unit for recognizing any one or a plurality of objects among three types of objects including a moving object, an animal, and a person as an object to be shielded; and a control unit for controlling the robot mechanism unit so as to carry out a work operation by using a first one of the robot arms of the robot mechanism unit, while shielding the object recognized by the object recognizing unit from entering a working space of the robot mechanism unit by putting a second one of the robot arms in a position between the working space in which the work operation of the first one of the robot arms is carried out and a movement space in which the object recognized by the object recognizing unit moves, wherein the control unit controls the robot mechanism unit so as to carry out a shielding operation by changing a distance between the object to be shielded recognized by the object recognizing unit and the second one of the robot arms, in response to a relative positional relationship between the object recognized by the object recognizing unit and the working space of the robot mechanism unit.
