I would like you to meet Rubi. Rubi can walk, crawl, go up and down stairs and can also stand up when he falls, but he certainly does everything in an unconventional way :) There's only one button on the screen; Push it to start/stop walking or when he gets stuck and stops moving. DO NOT push button when he's maneuvering (eg. Crawling, he will stand on his own) or he might short circuit :/ Rubi is not perfect, he sometimes gets confused and stuck, but don't be too hard on him, after all, he's only held together with bolts and nuts! it's a tough job being an intelligent robot! Enjoy!
