This paper shows a preliminary proposition to the mechanical design and, also kinematics and gap models for an active prosthesis applied to transtibial amputees. It is pointed that an active prosthesis is capable to absorb and amplify the forces during human walking. Tools applied to robotics like Denavit-Hartenberg's algorithm and the Lagrangean may be applied in mathematical modeling in order to...
The modeling of needle insertion into tissues is important for simulation of this procedure and for robotic technologies applied to percutaneous therapy. In this article, we present a first attempt to develop a general force model for the needle insertion throw different tissue layers (skin, fat and muscle) to reach an internal organ (the liver, for instance) with objectives of control, looking for...
This study describes a novel robotic system using haptic effects and objects, in rich, three- dimensional virtual environments (VEs) for the sensorimotor training of the hemiparetic hand. This system is used to train the hand and arm together as an integrated functional unit. Eight subjects with sub-acute or chronic strokes practiced two to three hours/day for 8 days using four different robotic simulations...
Medical robotic applications are increasing in operation rooms. It is necessary to select, locate and program appropriate robots for medical operations. SolidWorks and CosmosMotion controlled by the modeling and motion simulation programs created in VisualBASIC in this study are used for this purpose. The designer prepares the model input file which contains the information about the selected units...
