The final goal of this work is the development of functional rubber sheets with micro rubber structures such as friction free, adhesion, and impact adsorption rubbers, etc. We report a micro rubber structure that can successfully perform flexible passive walking with 3 V-shaped units consisting of 4 legs to achieve very low friction. We show how to miniaturize and integrate this structure to produce, by means of a micro rubber molding process using the stereo lithography method, a rubber sheet with 64 legs. The prototype is designed, fabricated, and tested. Under certain conditions, the 64-legged rubber sheet successfully realizes flexible passive walking down an incline.
