IEEE Transactions on Visualization and Computer Graphics, 2023 In this paper, we investigate the use of a motorized bike to support the walk of a self-avatar in virtual reality (VR). While existing walking-in-place (WIP) techniques render compelling walking experiences, they can be judged repetitive and strenuous. Our approach consists in assisting a WIP technique so that the user does not have to actively move in

Control of Walking Assist Exoskeleton With Time-delay Based on the Prediction of Plantar Force
IEEE Access, 2020 Many kinds of lower-limb exoskeletons were developed for walking assistance. However, when controlling these exoskeletons, time-delay due to the computation time and the communication delays is still a general problem.

Walking Gait of a Biped with a Wearable Walking Assist Device [PDF]
International Journal of Humanoid Robotics, 2015 A ballistic walking gait is designed for a planar biped equipped with a wearable walking assist device. The biped is a seven-link planar biped with two legs, two feet, and a trunk. The wearable walking assist device is composed of a bodyweight support, two upper legs, two lower legs, and two shoes.

Dynamic bipedal walking assisted by learning [PDF]
Robotica, 2002 SummaryThis paper presents a general control architecture for bipedal walking which is based on a divide-and-conquer approach. Based on the architecture, the sagittal-plane motion-control algorithm is formulated using a control approach known as Virtual Model Control. A reinforcment learning algorithm is used to learn the key parameter of the swing leg

Assisted walking in Malagasy dwarf chamaeleons [PDF]
Biology Letters, 2010 Chamaeleons are well known for their unique suite of morphological adaptations. Whereas most chamaeleons are arboreal and have long tails, which are used during arboreal acrobatic manoeuvres, Malagasy dwarf chamaeleons ( Brookesia ) are small terrestrial lizards with relatively short tails ...
