Effect of Step Length and Step Period on Walking Speed and Energy Consumption: a Parameter Study
Stability and performance are two main issues in motion of bipeds. To ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. However, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. Step length and step perio...
متن کاملDynamic walking: a step forward?
After a long time as a junior partner in robotics, walking has seen an explosion in interest and achievements in the last 15 years as computational power unimaginable until recently has been brought to bear on its problems. At the same time we have seen advances in other related fields: non-linear dynamics has helped us understand and model the robotic systems that we are studying; zoology has ...

متن کاملOptimal walking in terms of variability in step length.
The optimal condition in speed, step rate, and step length of human walking has been reported in terms of temporal consistency, energy cost, and attentional demand. No study, however, has been conducted on the optimal condition in terms of spatial variability of walking. This study examined whether there is an optimal walking speed with minimum intrasubject variability in step length and step w...
متن کاملEvaluation of optimal step length in a seven-link model with margin of stability method
In a walking cycle design, maximizing the upright balance should be considered in addition to the kinematic constraints, energy consumption rate must be considered. The purpose of this study is to find the optimal step length obtained for each person according to the physical features. In this research, in order to minimize energy consumption rate by considering maximum balance two cost functio...
