We were talking around the office here at ezrobot on this subject. What Is Your Preferred Method Of Robot Locomotion? The method of transportation can be currently available or not... meaning it’s okay to invent an idea!
I would REALLY love to make a robot that swims, and of course one that flies...one day.

I think the Boston Dynamics Handle has pretty awesome locomotion. So much potential combining bipedal style w/ wheels.
My preferred is using an Auto Position to create gaits. I really enjoy coming up with new ways to make a robot move - even if it's not useful
This is the weirdest robot that i made walk - named him Norm. You can get his app here: https://synthiam.com/Community/Apps?id=1999
