Modular climbing robot for service‐sector applications

Abstract

Fraunhofer Institute for Factory Operation and Automation (IFF). SIRIUS is a climbing robot meant for any vertical surface, regardless of the angle. The robot can be outfitted with tools to perform a variety of service‐sector tasks such as façade cleaning, building and ship coating, ship welding, inspection work on tanks, and so on. It is a modular system, and the robot can be adapted to almost any surface, independent of the surface material or obstacles. The robot stays attached to the surface via suction cup feet or magnetic grippers, and moves vertically on four linear guides that are coupled in two pairs. The new kinematics of the robot allow it to walk continuously in all directions. The robot overcomes obstacles by sensing their position and generating the necessary step length in order to maximize the number of suction cups attached to the surface while walking over the obstacle.
