In order to reducing motors energy consumption, the problem about motion function, which has torque feature (AV) m small, is discussed in this paper. Conventional functions and small torque moment function are used to control mass center motion of robot ZQROT-I respectively. In the process of robot running the straight gait , motion performance of the robot is analyzed by ADAMS. Analysis result indicates that function controlling mass motion of robot with small torque feature has significant meaning for saving working energy of robot.

The paper explains and demonstrates an improved integration architecture based on the Smart Client, for the current situation and the existing problems of the collaborative sales management system based on ASP (Application Service Provider, ASP) platform of auto-industry. The key technologies and strategies such as off-line supporting, smart deploying and updating for system application are explained, which are proved feasibly by practice.

Because the structural and motion parameters errors, when the robot move in the ideal situation, actual posture of the robot is likely to deviate from its required position. Based on the discussion of forward kinematics, which is calculating the influence of error sources on the posture error of robot, is researched in this paper, and an example is used to explain. The effect of each parameter on posture error can be evaluated by analyzing the results of example. The designer can make different error control method for each parameter according to the influence of them.

Rough set theory is a useful tool for attribute reduction of fault diagnosis for rotating machinery, but cannot be efficiently used to sample increased areas. Aiming at the problem of incremental attribute reduction, a novel attribute reduction algorithm was put forward based on the binary resolution matrix for the two updating situations and the algorithm had a low space complex. Finally, with the fault diagnosis experiments of the bearing, the attribute reduction method was proved to be correct.

According to the different fellower structure and general simple trapezoid motion law of cam mechanism, this paper established a mathematic model for the motion of fellower structure of cam mechanism. The design method of motion law of the fellower structure was introduced, and the law of motion transition of fellower system and the related issues with program design were studied. A design system was developed using VB code based fellower structure and general motion laws. And the system could solve the curve of motion law for the fellower system and the eigenvalue of the curve, and finally realize parametric design of motion law for the fellower structure of cam mechanism. And the system could calculate and output the coordinate of cam configuration, and improve the digitized design process of cam parametric. The interface of the designed system is friendly and convenient, and the system could be used in both engineering and teaching.
