Obstacle-navigation control for a mobile robot suspended on overhead ground wires

摘要

This paper presents an obstacle-navigation control strategy for a mobile robot suspended on overhead ground wires of power transmission lines based on a novel movement mechanism. The kinematics of the mobile robot and the process of obstacle-navigation control are analyzed in detail. This paper presents to develop robot expert system using hybrid programming of C language integrated production system (CLIPS) and C language, and the robot expert system has powerful logical reasoning ability and data processing ability. The robot control modes have layered planning and direct control. This paper describes the robot expert system with hybrid architecture and analyzed decision-making of obstacle-navigation in layered planning mode in detail. The robot can learn online or offline, and when it encounter the same obstacles, it can navigate them quickly. Obstacle-navigation control is the difficult point of the type of wire-suspended robot and the expert system can instruct the mobile robot to navigate obstacles autonomously on overhead ground wires.
