Digital Human Model (DHM) plays an important role in the design field. And how to make a static DHM into a dynamic model would be a critical issue for the application. Anthropometric landmarks are easily visualized by showing the landmark locations on the body. It is a natural extension to create 3D illustrations of the landmarks by placing then on 3D computer generated bodies. Our goal was to create...
This paper describes evaluation of grasping-easiness from perspective of dynamics with hand model. Evaluation of grasping-easiness, which is degree of easiness to grasp an object, is an important factor because it is useful to design better industrial products. We have developed a system for evaluation of grasping-easiness, which consists of the dynamics simulation space and the data glove. This system...
This paper presents image-based finger pose measurement for hand user interface. The aim of this measurement technique is to make a better user interface enabling three dimensional operation by hand. The measurement technique uses stereo vision, and approximates the hand motion based on anatomical constraints. Distinctive feature of the measurement technique is usage of ring markers, which enable...
The paper deals with the four legged walking robot Guará, built with obstacle overcoming capabilities. It was designed as a research robot platform, to be used in indoor environment, walking straight and curved paths and detecting and overcoming known obstacles. Straight paths are done with gait matrix strategy and curved paths are accomplished by the four legs which have differential strokes in...
The paper addresses the analysis of three methods for inverse kinematics of a 3-DOF medical parallel robot with R-P-S (Revolute-Prismatic-Spherical) joint structure using MATLAB/Simulink and dSpace platform. The three methods were implemented in MATLAB/Simulink and than exported to dSpace realtime development platform. A comparation between the times of these three methods has been studyed. The scope...
