I was really surprised when I saw the picture of the eight legged/wheeled rover (bottom of page 43, Spring 2008) in Robot Magazine. I shouldn't have been too surprised though, because I have a similar but I think better leg/wheel design.

I've solved the ground clearance problem.

I started working on a different hybrid rover/walker about 8 months ago, but mine is considerably different. I'll have to go look at my first post on the Lynxmotion Forums about it.
