An approach integrating planning and image-based visual servo control for road following and moving obstacles avoidance

摘要

This paper proposes an approach that integrates planning and image based visual servo control for road following and moving obstacle avoidance. One main objective of this article is to represent a robot's general plan or strategy in the form of a finite state machine or automaton. This automaton is designed previously to execution of the plan and then it is used for any instance of the robot's task. The visual servo control is used to regulate the robot's velocity according to the visual target (task specification) which depends on the state in the automaton. All the algorithms and control laws have been implemented and simulation results and experiments with a real scale-size car-like robot are presented and discussed.
