요약Bipedal locomotion in humans is a complex behavior, requiring impressive coordination of the neuromuscular system. There are many hypothesized motor control objectives describing how humans might optimally govern these coordinated efforts, including minimization of energetic expenditure. However, evidence suggests that the underlying objectives are more complicated than pure energy minimization. Further, these objectives have not been thoroughly investigated during more complicated walking tasks. The mechanics of speed-varying walking and exoskeleton assisted walking, for example, are not fully understood, which makes testing different possible walking objectives difficult. This work explored the physical behavior and underlying objectives of exoskeleton-assisted and unassisted walking. The spatiotemporal behavior during walking speed transitions was investigated experimentally. The findings indicate that the magnitude of the change in speeds affects how humans execute transitions, and that different people may preferentially utilize strategies to complete the task. To explore underlying walking objectives, a computational model was developed. Specifically, a moderately complex Hybrid Zero Dynamics based model with nonuniform foot shape and muscle-tendon dynamics at the ankle was developed. Equations of motion were derived and model validation simulations demonstrated that this model is capable of producing simulated gaits that match human walking for three different nonuniform foot shape parameterizations. Finally, three candidate walking objectives were tested for unassisted and exoskeleton-assisted walking. This was done using optimization, generating simulated gait by minimizing representative objective functions. The findings indicated that humans may minimize muscle activation during walking, however additional work is still necessary to determine how this goal is balanced with other objectives. Additional simulations were executed to identify sources of error between simulated and experimental gait in the model, providing insight into the limitations and possibilities for future work.
