Passive Walking

Going on with robots, in the last talk we presented another interesting paper, this time written by Tad McGeer:

“Passive walking with knees”

This is about the role of knees in passive dynamic walking bipeds. It is  shown that giving just a slope, gravity energy is sufficient to keep walking down a pair of legs. With no other motor input, the machine will settle into natural gait. This evidences that morphological computation is implicit in natural locomotion systems. In this sense, this paper has originated new contoller systems in which the CoT (Coefficient of Transportation) could be optimized getting it near to the human one (of 0.2 vs 3.27 of Asimo robot by Honda). Furthermore, also prosthetics field could benefit from these new controllers and maybe evolutionary computation has new roles and goals to accomplish, but that is just another research issue.
