Abstract

This paper presents a new search strategy based on models of evolution in order to solve the problem of collision-free robotic path planning. We designed the robot path planning method with genetic algorithm which has become a well-known technique for optimization, intelligent search. Considering the path points as genes in a chromosome will provide a number of possible solutions on a given map. In this case, path distances that each chromosome creates can be regarded as a fitness measure for the corresponding chromosome. The effectiveness of the proposed genetic algorithm in the path planning was demonstrated by simulation. The proposed search strategy is able to use multiple and static obstacles.

본 논문은 로봇 충돌회피 경로계획의 문제점을 해결하기 위해 진화된 모델에 근거한 새로운 경로탐색 전략을 소개한다. 최적화된 지능형 검색 방법으로 잘 알려진 유전자 알고리즘을 이용하여 로봇 경로계획 방법을 설계하였다. 염색체 안에 있는 유전자 인자로 경로점을 고찰해보면 주어진 맵에 대한 가능한 해법이제공된다. 생성된 염색체 간의 거리가 먼 경우 유사한 염색체에 대한 적합도로 간주할 수 있다. 경로계획에 있어 본 논문에서 제안한 유전자 알고리즘의 유효성을 증명하기위해 다양한 방법으로 시뮬레이션을 실시하였으며, 제안한 경로 검색 방법은 정지된 장애물이나 복잡한 장애물에도 사용될 수 있음을 증명하였다.
