An autonomous robot system for power distribution line maintenance work is developed. At the maintenance work level, one of the most repeated tasks is tightening a nut. The nut tightening task is carried over using a remote joystick under damping control, and the procedure for automatically tightening nut is considered and a feasibility study is conducted using an experimental robot system. If the...
This paper proposes a simple obstacle avoidance method for telepresence robot that is designed for families with elderly people living in remote areas. The proposed method is as follows: 1) Obstacle points are measured by tilting a LRF (Laser Range Finder), 2) Obstacle points that are inside a circle (Radius 0.75cm) at the center of LRF are projected to the arch of the circle, and 3) Openings that...
