چکیده

Knowledge of the human multi-joint arm viscoelastic properties is essential in the assistance of building human-like robots. In this paper, a robust estimation method of human multi-joint arm viscoelasticity during natural movement is reviewed, a human arm-like robot control scheme using the measured viscoelasticity from estimation method is proposed. In order to imitate how to adjust the human multi-joint arm viscoelasticity by central nervous system (CNS) according to external environment, a forward gaze model is used. The effectiveness of the proposed method is confirmed through simulation results based on experimental data from the real time estimation of viscoelasticity.

Operator-based Robust Nonlinear Tracking Control for A Human Multi-joint Arm-like Manipulator with Unknown Time-varying Delays

In this paper, an operator-based robust nonlinear tracking control for a human multi-joint arm-like manipulator with unknown time-varying delays is proposed by using robust right coprime factorization approach and a forward predictive operator. That is, first, considering the uncertainties of dynamic model consist of measurement error and disturbances, a nonlinear feedback control scheme is des...

Design and Analysis of a Novel Tendon-less Backbone Robot

A new type of backbone robot is presented in this paper. The core idea is to use a cross shape mechanism with the principle of functioning of the scissors linkages, known as a pantograph. Although this continuum arm acts quite similar to tendon-driven robot, this manipulator does not include any tendon in its structure. This design does not suffer from the weaknesses of the continuum design suc...
