Multi-Step Forward Dynamic Gait Simulation

چکیده
A predictive forward-dynamic simulation of human gait would be extremely useful to many different researchers, and professionals. Metabolic efficiency is one of the defining characteristics of human gait. Forward-dynamic simulations of human gait can be used to calculate the muscle load profiles for a given walking pattern, which in turn can be used to estimate metabolic energy consumption. One approach to predict human gait is to search for, and converge on metabolically efficient gaits. This approach demands a high-fidelity model; errors in the kinetic response of the model will affect the predicted muscle loads and thus the calculated metabolic cost. If the kinetic response of the model is not realistic, the simulated gait will not be reflective of how a human would walk. The foot forms an important kinetic and kinematic boundary condition between the model and the ground: joint torque profiles, muscle loads, and thus metabolic cost will be adversely affected by a poorly performing foot contact model. A recent approach to predict human gait is reviewed, and new foot contact modelling results are presented.

In this paper, we studied numerically both kinematic and dynamic models of a biologically inspired mammal-like octopod robot walking with a tetrapod gait. Three different nonlinear oscillators were used to drive the robot’s legs working as central pattern generators. In addition, also a new, relatively simple and efficient model was proposed and investigated. The introduced model of the gait ge...

In this paper an Energy Dissipation Rate Control (EDRC) method is introduced, which could provide stable walking or running gaits for legged robots. This method is realized by developing a semi-analytical pattern generation approach for a robot during each Single Support Phase (SSP).

This work explores regulation of forward speed, step length, and slope walking for the passive-dynamic class of bipedal robots. Previously, an energy-shaping control for regulating forward speed has appeared in the literature; here we show that control to be a special case of a more general time-scaling control that allows for speed transitions in arbitrary time. As prior work has focused on po...
