Structural Synthesis of Lower-Class Robot Manipulators with General Constraint One

Structural synthesis of Euclidean platform robot manipulators with variable general constraints

In this paper, new method for structural synthesis of Euclidean platform robot manipulators with variable general constraints (EPRM) is presented. Three dimensional motion of the base moving platform is generated by the motion of dyads on the Euclidean planes. Each dyad is connected to the moving base platform by universal, spherical or spherical in torus (St) kinematic pairs. This allows solvi...

General method for kinematic synthesis of manipulators with task specifications

This paper deals with the kinematic synthesis of manipulator. A new method based on distributed solving is used to determine the dimensional parameters of a general manipulator which is able to reach a set of given tasks speciied by orientation and position. First, a general Distributed Solving Method (DSM) is presented in three steps : the problem statement, the objective functions formulation...

An Adaptive Impedance Controller for Robot Manipulators

A desired dynamic behavior of constrained manipulators can be achieved by means of impedance control and various implementations of fixed controllers have been proposed. In this paper, and adaptive implementation is presented as an alternative to reduce the design sensitivity due to manipulator mismatch. The adaptive controller globally achieves the impedance objective for the nonlinear dynamic...

Adaptive RBF network control for robot manipulators

TThe uncertainty estimation and compensation are challenging problems for the robust control of robot manipulators which are complex systems. This paper presents a novel decentralized model-free robust controller for electrically driven robot manipulators. As a novelty, the proposed controller employs a simple Gaussian Radial-Basis-Function Network as an uncertainty estimator. The proposed netw...
