Abstract: This paper presents an overview of an ongoing project on a bio-inspired climbing caterpillar robot. First, an investigation on locomotion kinematics adopted by climbing robots is presented. After that, a related survey on the natural creatures which can climb on vertical surfaces in different materials is given. The special attention is emphasised on the natural caterpillars| locomotion mechanism. In this project, we combine climbing techniques with a modular approach to realise a novel prototype as a flexible wall climbing robotic platform featuring an easy-to-build mechanical structure, a low-frequency vibrating passive attachment principle and various locomotion capabilities. The research objects, system design and current achievements are presented step by step. In the end, a conclusion is given and the future work is outlined.
