Design and Gait Synthesis for a 3D Lower Body Humanoid
(University of Waterloo, 2013-01-02)Bipedal locomotion is a challenging control engineering problem due to the non-linear dynamics and postural instability of the bipedal form. In addition to these challenges, some dynamical effects such as the ground reaction ... -
Design Feasibility of an Active Ankle-Foot Stabilizer
(University of Waterloo, 2010-08-30)Walking is the most common form of mobility in humans. For lower limb mobility impairments, a common treatment is to prescribe an ankle-foot orthosis (AFO) or brace, which is a passive device designed to resist undesired ... -
Determinants of Increased Energy Cost in Prosthetic Gait
(University of Waterloo, 2004)The physiological energy requirements of prosthetic gait in lower-limb amputees have been observed to be significantly greater than those for able-bodied subjects. However, existing models of energy flow in walking have ... -
Effects of a Single Shift of Occupational Childcare on Knee Mechanics during Gait
(University of Waterloo, 2024-04-16)The current literature shows that there are ergonomic challenges in occupational childcare, such as inappropriate heights of furniture for adults, and that childcare educators engage in high knee flexion positions beyond ... -
Gait shape control for 2-D.O.F bipedal robots using hybrid virtual holonomic constraints
(University of Waterloo, 2014-07-29)Motion control for bipedal robots is an active research area because bipedal robots can perform tasks and work in terrain where wheeled robots cannot. Researchers have developed bipedal robots that are able to walk, run ... -
Gaits and Their Development in the Infraorder Pecora
(University of Waterloo, 1967-02)The gaits of twenty-eight species of the Infraorder Pecora are analyzed from motion picture sequences comprising over 45,000 frames. For each gait the percentage time spent on the various supporting legs during each stride ... -
How does emotion affect the way we walk?
(University of Waterloo, 2022-09-22)Gait, the way that human beings walk, is a large component and indicator of health in both young and older adults. Gait has been used in the past to identify injury and fall risk, progression of diseases and is used as a ... -
A hybrid inverse dynamic-neural network approach to lower limb exoskeleton control
(University of Waterloo, 2022-08-22)A powered machine that is wearable over all or part of the human body can be referred to as a powered exoskeleton. The role of powered exoskeletons is usually to provide ergonomic structural support while using motor power ... -
The Physical Exoskeleton-User Interface: Investigating Modelling and Design of Coupling Surfaces
(University of Waterloo, 2023-07-27)The goal of Lower Limb Rehabilitation Exoskeletons is to provide active and passive support to the user for rehabilitation goals focused on the restoration of function and independence to the user. In circumstances where ... -
Recovering Optimal Cost Functions for Natural Walking: From Musculoskeletal Simulation to Exoskeleton Control
(University of Waterloo, 2022-05-03)Human movement studies have contributed to our understanding of how the central nervous system's (CNS) interactions with our body results in rich and complex motor behaviours, such as human gait. Such understanding is ... -
Understanding the influence of anxiety on gait in Parkinson's disease
(University of Waterloo, 2015-07-15)Anxiety is a prevalent non-motor symptom of Parkinson’s disease (PD) and has been linked to motor impairments in PD, yet there is a huge gap in the understanding of whether anxiety affects movement, namely gait, in those ...
