COORDINATED WORK OF TWO MOBILE ROBOTS WHEN PERFORMING OPERATIONS AUTOMATICALLY IN A COMPLEX ENVIRONMENT

Annotation

The problem of controlling a manipulator mounted on the main mobile robot performing operations in cramped working environment conditions when objects of work are out of sight of the robot's technical vision system, is considered. In this situation, location of the invisible objects is first determined using the technical vision system of an auxiliary and more maneuverable mobile robot in its associated coordinate system, and then this information is transmitted via communication channels with unavoidable errors to the associated coordinate system of the main manipulation robot. An algorithm is proposed to determine and eliminate the aroused errors, which as a result provides the possibility of accurate automatic execution of the required operations with the objects of work. The proposed mathematical apparatus allows for accounting variations in current spatial orientation of the base platforms of both mobile robots at the angles of roll, pitch and yaw in the absolute coordinate system. The results of experiments confirming the operability and high efficiency of the proposed method of coordinated automatic operation of two mobile robots in cramped environmental conditions are presented.
