Development of a Crawling Robot for Large Steel Structure Welding

The welding process of large steel components is mainly manual, with high labour intensity, high risk factor and low operational efficiency, which cannot meet the requirements of modern enterprise manufacturing. This paper proposed a crawling robot, which is combined with a 6-axis robot through a magnetic suction mobile chassis, and uses a laser tracking system to guide the crawling robot to walk, which solves the problem of the restricted working space of the traditional crawling robot. The crawler welding robot has good mobility and high degrees of freedom, and can be adapted to automated welding of large steel components.
