Function synthesis of Bennett 6R mechanisms using Chebyshev approximation
This study focuses on approximate function synthesis of the three types of overconstrained Bennett 6R mechanisms using Chebyshev approximation. The three mechanisms are the double-planar, double-spherical and the plano-spherical ...
Conceptual design of a 2-DoF planar high-speed industrial parallel manipulator
This study focuses on conceptual design alternatives for a planar high-speed/high-precision manipulator in terms of mechanism structure, control strate-gy, and drive system selection. These concepts are investigated ...
Geometrical analysis of a continuously variable transmission system designed for human-robot interfaces
New robotic systems are placed out of their constrained workspaces in order to work alongside humans. Consequently, these applications call for robots monitoring and regulating physical human-robot interaction. These robots’ ...
Structural compliance effects on the accuracy and safety of a R-CUBE haptic device
This paper addresses the contribution of structural compliance on stiffness and safety of a R-CUBE Haptic Device. Structural compliance is determined in several poses via FEM analysis and addressed by referring to local ...
An experimental test procedure for validation of stiffness model: A case study for R-CUBE parallel mechanism
Haptic device manipulators are used for generating haptic feedback. This feedback is composed of force which is regulated with respect to motion information. Accurate generation of the feedback requires exact position ...
Control methods for a teleoperated endoscope robot
In this study, control of a endoscope robot for the pituitary gland surgery is presented. This co-worker robot has non-backdrivable actuation system with external brakes on the actuators. Since it is required to move in a ...
