Hydraulic-and-electric Double-arm Robot

The Russian Myo-electric Arm.

Control of Flexible Robot Arm

T h i s work is a computer simulation of the control of flexi ble robot arm. The dynamic equations for a single-link flexible robot arm have been derived rigorously. Th is arm has two degrees of freedom in rotation and one in translation so that the workspdce i s three-dimensional. The payload is simulated by attaching additional mass to the arm at a specified location. The governing equations ...

Experimental adaptive control of a hydraulic robot

An adaptive position controller is investigated to compensate for the effects of both the actuator and linkage dynamics in a four axis hydraulic robot. A simulation study was done, prior to the experimental implementation, in order to compare and contrast different adaptive control algorithms for this system. The dynamics of the linkage were developed using Lagrangian techniques. The equations ...

Friction Compensation for an Industrial Hydraulic Robot

oint friction is one of the major limitations in performing high J precision manipulation tasks. It affects both static and dynamic performances, and may cause instability when coupled to position or force feedback control. Thus, compensating for joint friction has been one of the main research issues in robot design and control over the years. The aim of this paper is to show how friction comp...

Modeling and Control of a Hybrid Hydraulic-Electric Propulsion System

The utilization of renewable energies as an alternative for fossil fuels is considerably growing due to an increasing environmental concern and exhaustion of fossil fuels [1-3]. Transportation electrification is one way to replace or reduce fossil fuels with renewable energy sources. Several propulsion systems including hybrid electric vehicles and plug in hybrid electric vehicles have been int...
