Roboclimber, the 3 tons spider

Purpose – The aim of the research is to design, build and test a robot able to autonomously execute slope consolidation tasks. Design/methodology/approach – A multidisciplinary approach has been adopted to solve the problem: mechanical and control architecture have been conceived simultaneously. Modularity and lifecycle are considered. The robot can climb by means of four legs and two ropes. The drilling system is hosted onboard. Drilling process is fully automated, motion can be controlled in tele-operation. Findings – The performance of the first prototype has satisfied the end-user; new on-site tests and improvements are planned. Research limitations/implications – Roboclimber is cumbersome; both robot transport and on-site positioning are complex operations. Coordination between legs motion and ropes tensioning is a difficult task. Practical implications – The system reduces operating costs and working time, while avoiding the human presence in unsafe and harsh environments. Originality/value – Roboclimber is the first robot able to do heavy duty works on rocky walls
