in this paper robust pid control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. in dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. to develop the idea of control for cable robots with elastic cables, a robust pid control for cable driven robots with ideal rigid cables is firstly de...

ABSTRACT: Kinematics and dynamics analysis of a 6-DOF parallel robot is performed. The mechanism of this parallel robot is composed of a moving platform and a static platform, the platform are linked by 6-UPS branched chains. The position and pose of the robot moving platform are totally described by 6 variables, including 3 displacement and 3 angles of a reference point on the platform. Firstl...

This paper describes the design and implementation of functionally distributed control architecture for real-time control of robot systems. Robot systems must control several functions in parallel for decision, action, and recognition. In order to fulfill this requirement, we propose the architecture based on parallel/distributed control. The robot system based on this architecture is designed ...

Cardiopulmonary resuscitation (CPR) has been a very important requirement for the purpose of rescue of patients in emergency. But unavailability of trained technicians at the time of need has been a problem. Robotic systems capable of performing the cardiopulmonary resuscitation can be a potential solution. In this paper, a design of robotic system for CPR and its optimization has been presente...

The aim of this study is to investigate the capability of a 6-DoF parallel robot to perform various rehabilitation exercises. The foot trajectories of twenty healthy participants have been measured by a Vicon system during the performing of four different exercises. Based on the kinematics and dynamics of a parallel robot, a MATLAB program was developed in order to calculate the length of the a...

This paper presents the design of our new 33 degree of freedom full size humanoid robot, SAFFiR (Shipboard Autonomous Fire Fighting Robot). The goal of this research project is to realize a high performance mixed force and position controlled robot with parallel actuation. The robot has two 6 DOF legs and arms, a waist, neck, and 3 DOF hands/fingers. The design is characterized by a central lig...

Surgery is one of the fields where robots have been introduced due to their positioning accuracy which exceed the human capabilities. Parallel robots offer higher stiffness and smaller mobile mass than serial ones, thus allowing faster and more precise manipulations that fit medical applications. In the paper is presented the modeling and simulation of a new parallel robot, based on an innovati...

JCSPre is a highly reduced version of the JCSP (Communicating Sequential Processes for Java) parallel programming environment. JCSPre has been implemented on a LEGO Mindstorms NXT brick using the LeJOS Java runtime environment. The LeJOS environment provides an abstraction for the NXT Robot in terms of Sensors, Sensor Ports and Motors, amongst others. In the implementation described these abstr...
