This paper proposes the kinematic resolution method of CoM(center of mass) Jacobian with embedded motions and the design method of posture/walking controller for humanoid robots. The kinematic resolution of CoM Jacobian with embedded motions makes a humanoid robot balanced automatically during movement of all other limbs. Actually, it offers an ability of WBC(whole body coordination) to humanoi...

This paper describes a collection of optimization algorithms for achieving dynamic planning, control, and state estimation for a bipedal robot designed to operate reliably in complex environments. To make challenging locomotion tasks tractable, we describe several novel applications of convex, mixed-integer, and sparse nonlinear optimization to problems ranging from footstep placement to whole-...

Background & Aims: Parkinson’s disease after Alzheimer is the second most common neurological disorder and one of the most important motor effects of this disease, which is seen in its final stages, is walking disorder. The purpose of the present study was to investigate the effect of motor imagery-walking and observation-walking on relearning walking skill in Parkinson’s disease. Materials & ...

Walking animals, like stick insects, cockroaches or ants, demonstrate a fascinating range of locomotive abilities and complex behaviors. The locomotive behaviors can consist of a variety of walking patterns along with adaptation that allow the animals to deal with changes in environmental conditions, like uneven terrains, gaps, obstacles etc. Biological study has revealed that such complex beha...

PURPOSE This cross-sectional study takes a unique look at the association between patterns of walking and cognitive functioning by examining whether older adults with mild cognitive impairment differ in terms of the community settings where they walk and the frequency, intensity, or duration of walking. DESIGN AND METHODS The sample was based on interviews with 884 adults aged 65 years and ol...

During human walking, perturbations to the upper body can be partly corrected by placing the foot appropriately on the next step. Here, we infer aspects of such foot placement dynamics using step-to-step variability over hundreds of steps of steady-state walking data. In particular, we infer dependence of the 'next' foot position on upper body state at different phases during the 'current' step...

Objective: The purpose of this study was to compare vertical ground reaction force during forward and backward walking among the male professional Karatekas with genu varum and normal knee. Methods: 20 professional male Karates (in genu varum and normal groups) participated in this semi-experimental study. The vertical ground reaction force was measured using force plate system during forward ...

PURPOSE Evaluate the relationship between neighborhood crime and the amount of daily walking by minority adults. DESIGN This was a cross-sectional study of minority adult walking behavior and crime. Setting. Oakland, California was chosen as the study area because of the substantial spatial variation in levels of criminal activity combined with detailed information on walking trips. PARTICI...
