The Real Elliot writes – “Build your own (needlessly tech) servomotor-driven 4-leg walker robot!

First, a warning: This bot is basically a microcontroller-brain version of the classic BEAM 4-legged walker. The BEAM 4-legger may be easier for you to make if you aren’t already set up for microcontroller programming and just want to build a walker.

On the other hand, if you’re getting started with microprocessor programming and have a couple servos kicking around, this here’s your ideal project! You get to play with walker mechanics without having to worry about the fussy analog BEAM microcore tweaking.”Link.
