This study introduces the concept design and analysis of a robotic system for the assistance and rehabilitation of disabled people. Based on the statistical data of the most common types of disabilities in Spain and other industrialized countries, the different tasks that the device must be able to perform have been determined. In this study, different(More)
— This paper describes a new parallel robot with 6 degree of freedom (dof) and decoupled kinematics. The robot is composed of six legs with actuated prismatic joints; three legs control the spatial position of the center of the mobile platform, while the remaining legs are used to define the end effector orientation. The decouple kinemat-ics is obtained by(More)
In this work, the dimensional synthesis of a spherical Parallel Manipulator (PM) with a 3PSU-IS kinematic chain is presented. The goal of the synthesis is to find a set of parameters that defines the PM with the best performance in terms of workspace capabilities, dexterity and isotropy. The PM is parametrized in terms of a reference element, and a(More)
In this paper we propose a strategy for modelling a human hand for Haptics interaction.The strategy consists in a parallel computing architecture that calculates the dynamics of a hand, this is accomplished by computing the dynamics of each finger in a parallel manner. In this approach multiple threads (e.g. haptics thread, graphics thread, collision(More)
In this paper the trajectory planning problem is solved for a 2PRR parallel manipulator which works in cooperation with a 1 degree-of-freedom (dof) platform. The whole kinematic chain is considered as a redundant 3-dof manipulator, and an algorithm is presented to solve the redundancy by using the joint velocities in the null space of the jacobian matrix.(More)
