Why use a tetrahedron as the basic design shape of the walker? Why not improve the wheel?
The wheel is ancient technology. Moreover, the most interesting places in universe are located in and on places where the wheel cannot go. The wheel cannot climb, step, reconstruct, glide, etcbefore humans can explore the unknown; it becomes feasible to develop probes that can gather information on the places humans seek to explore. It is vital and necessary to have robots with many degrees of freedom for missions to the unknown. Like the many degrees of freedom found within the human body structure, the TeTWalker will be able interact with its environment by climbing, walking, bracing for impact, extending, tumbling, stepping over, self healing, etcin order to ensure a successful mission.
