WebJul 5, 2024 · Data-tracking dynamic optimization problem. For both walking and running a dynamic optimization problem was formulated to calculate the set of muscle excitations (controls) that reproduced measurements of the time histories of all body-segmental motions and ground reaction forces over one stride cycle. WebJun 28, 2024 · In this study, we simulate human walking augmented by a powered ankle exoskeleton. The walking problem was formulated as a predictive dynamic optimization in which both the optimal assistive device torque and the gait were solved simultaneously. Cases with exoskeletons assisting one ankle and both ankles were considered.

WebMay 12, 2016 · A new “whole close-chain mechanism” concept is proposed for the design of the modular legged unit of walking vehicles. Based on this concept, the walking vehicle called dual quadruped vehicle is developed and constructed. The vehicle designed as an omnidirectional carrying platform contains two identical single-driven quadruped … WebJul 6, 2006 · Forward dynamic simulations of human walking gait have typically simulated and analyzed a single step of the walking cycle, assuming symmetric and periodic gait. To enable simulations over many steps, a stabilizer is required to maintain the balance of the walking model, ideally mimicking the human balance control mechanism. This paper … WebMar 18, 2010 · A review of human walking modeling and simulation is presented. This review focuses on physics-based human walking simulations in the robotics and biomechanics literature.
