Well well, here’s yet another wall-climbing robot - the Waalbot. that one features just three legs though, using dry adhesion to stick to walls and ceilings as it climbs. Why the tri-leg design? Well, it utilizes simple rotary actuators for a restricted degree of freedom motion, but plus throws in passive joints and elastic flexures which allows that motion to supply the preload and peeling forces essential to climb using dry

adhesion. The Waalbot is ap roduct of Carnegie Mellon University, and is tiny sufficient to be controlled by virtually any one, overcoming tiny obstacles and low angle surface curvatures with ease thanks to the legged motion. I wonder when will the military recruit that little bugger.
