Stairs? Or any other rough terrain where wheels are insufficient.

A robotics mentor once told me "just use bigger wheels" for rough terrain rather than legs and fancy control algorithms. But stairs are particularly difficult for wheels. House bots will almost certainly need legs to maximize utility. Unless they are so cheap you can get one for every surface.

> wheels are insufficient

Tell that to these guys: https://www.youtube.com/watch?v=v1apqfrJYwk. I think one day we have have two wheeled robots with these kind of capability.

That is badass. And energy intensive. I do think we will have legged/wheel hybrids rolling for efficiency and walking/hopping/etc for the difficult parts. He was certainly using his legs to perform those maneuvers. Wheels only can't bounce up. Wheelies, but not the hopping part. Wheelies + AWD may do it though. Good perspective. Thank you.
