Camels and Fennec Foxes: A Case Study on Biologically Inspired Design of Sand Traction Systems

This paper presents a demonstration of how biological solutions to mobility in the desert can be used to drive new concepts for sand-traction tires. Biological inspiration is used to translate both camel hooves (shape) and Fennec Fox paw texture (material) into design concepts for tire traction that are prototyped and tested. The steps used in this are captured in a case study of bio-inspired design, with the resulting concepts compared in terms of their performance. It was found that the camel hoof inspired “concave” shaped tire improved traction that the Fennec Fox paw textured “miner’s moss” surface on tires improved traction, and that the integrated solution of the two also improved traction. The greatest improvement was seen with the Fennec Fox textured concepts. Recommendations are made for improvements to steps of bio-inspiration for ideation and future traction concepts.
