Semi-Automatic Visual Support System with Drone for Teleoperated Construction Robot

In this paper, we describe a semi-automatic viewpoint moving system that employs a drone to provide visual assistance to the operator of a teleoperated robot. The objective of this system is to improve the operational efficiency and reduce the mental load of the operator. The operator changes the position of the drone through an interface to acquire the optimal assist image for teleoperation. We confirmed through an evaluation experiment that, in comparison with our previous study in which the final positions of the drone were determined in advance, the proposed method improves the operational accuracy and reduces the mental load of the operator.
