A model for selecting alternate foot placement during human locomotion
The selection of alternate foot placement is based on visual inputs and the prediction of future foot placement combined with a set of internal rules that are guided by three determinants: minimum foot displacement, stability, and maintenance of forward progression. These three determinants are weighted differently, depending on different constraints. The first purpose of this review is to defi...
متن کاملValidating determinants for an alternate foot placement selection algorithm during human locomotion in cluttered terrain.
The goal of this study was to validate dynamic stability and forward progression determinants for the alternate foot placement selection algorithm. Participants were asked to walk on level ground and avoid stepping, when present, on a virtual white planar obstacle. They had a one-step duration to select an alternate foot placement, with the task performed under two conditions: free (participant...
متن کاملDeterminants and Strategies for the Alternate Foot Placement
Undesirable landing area (e.g., a hole, a fragment of glass, a water puddle, etc) creates the necessity for an alternate foot placement planning and execution. Previous study has proposed that three determinants are used by the central nervous system (CNS) for planning an alternate foot placement: minimum foot displacement, stability and maintenance of forward progression. However, validation o...
متن کاملLearning to Step: Models of Foot Placement for Biped Locomotion
In this paper, we propose different models for estimating foot placement in biped locomotion. We use either learning approach or optimization approach to obtain such models. We evaluate these models in terms of robustness and complexity. Our results show that these models are more flexible than Inverted Pendulum Model and they provide more agility for biped locomotion under different walking sp...
متن کاملA universal ankle-foot prosthesis emulator for human locomotion experiments.
Robotic prostheses have the potential to significantly improve mobility for people with lower-limb amputation. Humans exhibit complex responses to mechanical interactions with these devices, however, and computational models are not yet able to predict such responses meaningfully. Experiments therefore play a critical role in development, but have been limited by the use of product-like prototy...
