Stability analysis of four-point walking.
The aim of the experiment reported here was to determine the static and dynamic stability of two-point stance phases when walking on hands and knees at different speeds. In addition, we defined the methods and predicted the consequences of including two-point stance phases into crutch assisted functional electrical stimulation (FES) walking. Crawling on hands and knees was performed at three sp...
متن کاملControl concepts for walking based on point-mass 3D models
In the field of bipedal locomotion, many researchers use controllers based on simple point mass models to achieve walking balance [1, 2, 3, 4, 5]. In these models, balance is ruled by center of mass (CoM) position and velocity, foot placement and its timing, and pushoff impulses. But is this also true for a more complex, many-DOF, robot? Does upper body motion significantly influence CoM dynami...
متن کاملKinematic modeling of four-point walking patterns in paraplegic subjects
We present a kinematic model of a paraplegic subject walking with crutches where the subject with the crutches is modeled as a parallel kinematic structure. The model is employed to investigate if certain quadrupedal gait patterns can be implemented with functional electrical stimulation. The study is motivated by the fact that the existing crutch-assisted gait realized by the electrical stimul...
متن کاملWalking perception by walking observers.
People frequently analyze the actions of other people for the purpose of action coordination. To understand whether such self-relative action perception differs from other-relative action perception, the authors had observers either compare their own walking speed with that of a point-light walker or compare the walking speeds of 2 point-light walkers. In Experiment 1, observers walked, bicycle...
متن کاملWALKING WALKing walking: Action Recognition from Action Echoes
Recognizing human actions represented by 3D trajectories of skeleton joints is a challenging machine learning task. In this paper, the 3D skeleton sequences are regarded as multivariate time series, and their dynamics and multiscale features are efficiently learned from action echo states. Specifically, first the skeleton data from the limbs and trunk are projected into five high dimensional no...
