Presentation of Realistic Motion to the Operator in Operating a Tele-operated Construction Robot

Abstract

In this study, a tele-operated construction robotic system was developed. An important problem to be solved in such a system is how the operator can feel the presence of working fields in a high quality. To solve the problem, in this paper, a new control method of employing the 3-DOF motion base is investigated to generate such a realistic motion as produced by a 6-DOF motion base. In order to confirm the validity of this control method, an evaluation experiment has been preformed. According to the experimental result, with both visual information and the motion of the robot, the operator on the 3-DOF motion base could feel the motion of not only roll, pitch and heave, but also surge, sway and yaw as well.
