Abstract :
One of the goals of human walking is to produce safe foot trajectories which end in gentle foot placements. The authors present a computer simulation that uses internal models and feedforward control laws to explain anticipatory behavior exhibited by subjects during obstructed walking. A hierarchical structure allows present mechanical behavior to be adapted in advance of future mechanical requirements while precompensating for certain system delays.<>
