Wheel-legged robot

Wheel-legged robots

I like wheel-legged robots, I really want to build one by myself or buy one in the future.

Some famous wheel-legged robots. From left to right: Ascento 1st version and Ascento 2nd version from Ascento Robotics; Diablo from Direct Drive, Skateo from Czech Technical University in Prague, Handle from Boston Dynamics.
I think wheel-legged robots achieve a good balance between functionality and complexity.
