I just taught I'd show you this cool clip of a Bioloid robot climbing a wall
Bioloid goes climbing - Part 1 - climbing process I think it's pretty cool, I recently got the beginner Bioloid kit which is great but I don't have anywhere near enough servos to make a robot capable of this. I'm hoping to somehow connect normal motors or servos to my Bioloid control unit and thus have as many motors or servos as I want but until then I'll work with what I have. Still a very cool kit.
