Precise teleoperation of deztrous robotic hands b y hand masters requires an accurate human hand model. A kinematic model of a human index finger is developed as an example for human hand modeling. The parameters of the model are determined b y open-loop kinematic calibration. Singular value decomposition is used as a tool for analyzing the kinematic model and the identification process. Accura...

Via Study’s kinematic mapping S the 6-parametric Lie group SE(3) of direct Euclidean displacements can be identified with a certain hyperquadric M6 in 7-dimensional real projective space. The mapping has nice geometric properties; for instance one parametric rotation groups are represented by straight lines on M6, coordinate transformations in Euclidean 3-space are represented by special automo...

in this article a new and an accurate method for kinematic and dynamic analysis of a parallel robot 3prs and a hybrid robot (parallel and serial) 3prs-rrp are presented, which is based on the denavit-hartenberg transformation matrix algebra. first, basic properties of various kinds of robots are compared, and then the denavit-hartenberg parameters and their table are introduced. next, the metho...

objectives: the aim of this study was to extract suitable spatiotemporal and kinematic parameters to determine how total knee replacement (tkr) alters patients’ knee kinematics during gait, using a rapid and simplified quantitative two-dimensional gait analysis procedure. methods: two-dimensional kinematic gait pattern of 10 participants were collected before and after the tkr surgery, using a ...

Precise, long-range, airborne GPS kinematic positioning requires the use of carrier phase measurements, the data processing of which suffers from the technical challenges of "on-the-fly" ambiguity resolution and cycle slip repair. In this paper the authors describe how the combination of an 'ambiguity recovery' technique and a 'linear bias correction' method has been used to support oceanograph...

When creating datasets for modelling of human skills based on training examples from human motion, one can encounter the problem that the kinematics of the robot does not match the human kinematics. Presented is a simple method of bypassing the explicit modelling of the human kinematics based on a variant of the self-organising map (SOM) algorithm. While the literature contains instances of SOM...
