The field of control of redundant articulated mechanical systems requires the use of algorithms to compute the inverse kinematics. The fields of animation, virtual reality or game in particular, are very interested in these algorithms. We propose in this paper a comparison between several algorithms of incremental type. The considered application concerns the accessibility evaluation of an environment...
In this paper an idea of the elastic band method was exploited to design a repeatable inverse kinematics algorithm for robot manipulators. The method incorporates an optimization process at many stages of its performance and admits some extensions. Performance of the algorithm was illustrated on models of the three DOF planar pendulum and the PUMA robot. A comparison with a standard pseudo-inverse...
The built environment accessibility evaluation is required if the person physical capacities no longer correspond to the habitat requirements, which generally occur after an accident. For the person with disabilities, the inner accessibility of habitat is a highly important factor that allows him to live and work independently. This paper presents a new approach to determine the accessibility of handling...
This paper is a practical guideline on how to analyze and evaluate the literature algorithms of singularity- robust inverse kinematics or to construct new ones. Additive, multiplicative, and based on the Singularity Value Decomposition (SVD) methods are examined to retrieve well-conditioning of a matrix to be inverted in the Newton algorithm of inverse kinematics. It is shown that singularity avoidance...
