Analysis of Human Perception Ability for Robot Impedance

چکیده
This paper examines human impedance perception ability during manipulation of an impedance-controlled robot, especially as regards perception accuracy and differential limen. In the experiments, a subject is instructed to move the handle of an impedance-controlled robot and to perceive the presented value of the robot impedance. Experimental results show that both motor control ability and somatosensory information play important roles in impedance perception. Copyright c ©2005 IFAC

Variable Impedance Control for Rehabilitation Robot using Interval Type-2 Fuzzy Logic
In this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. The majority of existing control approaches are based on control torque strategy, which require the knowledge of robot dynamics as well as dynamic of patients. This requires the controller to overcome complex problems such as uncertainties and nonlinearit...
متن کاملMotion Dependence of Impedance Perception Ability in Human Movements
The present paper investigates the motion dependence of human impedance perception ability, especially in the stiffness perception through experiments. Experimental results demonstrate that the desirable hand displacement changes according to the robot stiffness, and that the deep somatic sensation has an important role in the stiffness perception. A preliminary training test is conducted for d...
متن کاملWorkspace Boundary Avoidance in Robot Teaching by Demonstration Using Fuzzy Impedance Control
The present paper investigates an intuitive way of robot path planning, called robot teaching by demonstration. In this method, an operator holds the robot end-effector and moves it through a number of positions and orientations in order to teach it a desired task. The presented control architecture applies impedance control in such a way that the end-effector follows the operator’s hand with d...
