Multi-Ped Walking Tractor, built between 1947 and 1949 by Multi-Ped Traction Ltd, Edmonton, Alberta on Case Model R Tractor by Edward Snell and Aimee Dragon. They wanted to move on muskeg by walking rather than roll with wheels which sunk. Walking is a kind of dream for humans but it is not said if this heavy Multi-Ped was successful.

Soft Spherical and soft wheel robot of Shinichi Hirai, Shiga, Japan. These robots are capable off rough terrain locomotion by its rolling and jumping. A robot consisting of deformable soft body and flexible actuators can roll and jump on the ground by the deformation of its body.   http://www.ritsumei.ac.jp/




Spherical Robots. From L to R, downwards : Spherical robot of Nils Völker, 2009, Rotodus AB, Sweden, 2005, Swarm 2, 2008, Groundbot, 2008, Inside the sphere, a pendulum is moved by an engine in a direction to displace center of gravity of the set and robot goes ahead. To turn right or left, the pendulum is displaced right or left. It seems the sphere can roll on flat ground (mud, snow, sand) but only little obstacles can be overcome. Used for surveillance. http://www.nilsvoelker.com/nxt/spherical/index.html


Terminatorbot Crawler Robot, 2008, from University of Denver, Colorado, moves with its limbs, also used as manipulators.
