The experimental results show that the model is convenient,it is suit for robot arm/hand system,and it is in favor of computer solution.

Using dynamic equation base on the screw theory for open-chain manipulator,we derive robot arm and dexterous hand dynamic mode and the equation of external force on the joint,study the connection between the two model,and put forward a robot arm&hand system dynamic model,and resolve error cumulation problem by violation correction method.

Conventional robot arm has only actuators similar to mono-articular muscles,though animal s arm has not only mono-articular muscles but also bi-articular muscles.

This paper proposes a new spring balance structure used for the robot arm.

Design of arm robot for assistant teaching based on VB;

Presented is an arm robot network system for teaching and experiment, which uses B/S architecture model with three layers to provide the educational services such as remote control, remote supervision and experimental simulation.

This paper introduces an arm robot network experiment system for teaching, which uses a B/S architecture mode l with three layers and provides the educational services such as the remote con trol, the remote surveillance and the simulation of arm robot.

Design of fuzzy controller based on expert system s manipulator;

The complexity of dynamic model of the flexible manipulator and parameter perturbation and uncertain disturbance in the system has emphasized the idea of applying new robust control in order to attain both stability and good performance which the tradi tional controllers can t achieve at the same time .
