This paper presents an initial work of identifying the dynamic parameters for cable-driven parallel robot (CDPR), CRAFT with a rigorous protocol. An orbital trajectory platform is designed in order to get pure translation movement platform. evolves plane and allows identification four parameters, mass first three moments along main axes. The results obtained respectively from data experimental ...

Product oil tankers are essential transportation equipment for petroleum transfer. Due to products’ intense penetration and solubility, the quality requirements coating product high, regular maintenance is needed. Currently, this relies on manual labor, which involves working in enclosed spaces with harsh conditions, high labor intensity, long time periods, unstable quality. We proposed a light...

This paper introduces a novel method for Cartesian trajectory and performance optimization control of kinematically-redundant truss-based manipulators (TBMs): The Virtual Serial Manipulator Approach. The approach is to model complex parallel-actuated TBMs as simpler kinematically-equivalent virtual serial manipulators. Standard control methods for kinematicallyredundant serial manipulators can ...

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...

This article presents a new planar translational cable-direct-driven robot 1 (CDDR) with actuation redundancy and supported against loading normal to the 2 motion plane with a passive planar two-degree-of-freedom SCARA-type (Selective 3 Compliance Assembly Robot Arm) serial manipulator. This allows the robot to 4 resist cable sag without being supported on the motion plane. The proposed robot 5...

JAXA studies the new locomotion concept using tethers for the requests of unmanned support system for astronauts and the robot demonstration on the orbit will be planned in 2012, called Robot Experiment on JEM/ISS (REX-J). This paper introduces the details of REX-J project and explains the proposal locomotion method called the tether based locomotion. The tether based locomotion is defined as a...

Abstract Cable-driven hyper-redundant robots have been adopted in many fields for accessing harsh and confined environments that maybe inaccessible or dangerous humans. The cable actuation strategy makes the robot hardware safer increases payload reducing its weight. In this paper, a novel design of fully actuated cable-driven has proposed. This solution is pulleyless decreases mechanical compl...

Cable-driven parallel robots are a special type of robot in which an end-effector is attached to fixed frame by means several cables. The position and orientation the can be controlled controlling length These present wide range advantages, control algorithms required have greater complexity than those traditional serial robots. Measuring cable tension important task this as many rely on inform...
