Cooperative Reconfiguration for a Reconfigurable Mobile Robot LIU Tonglin, WU Chengdong, LI Bin, LIU Jinguo （1. State Key Laboratory of Robotics, Shenyang Institute of Automation, Chinese Academy of Sciences, Shenyang 110016, China; 2. Graduate School, Chinese Academy of Sciences, Beijing 100049, China; 3. School of Information Science ＆ Engineering, Northeast University, Shenyang 110004, China）Abstract： A main characteristic of the reconfigurable mobile robot AMOEBA-1 is that it has diverse configurations, but some reconfigurations are difficult to realize under the influence of ground conditions. A cooperative reconfiguration method is proposed to reduce reconfiguration resistance and enhance the adaptability of the robot to the environment. The mathematical model is established correspondingly. The kinematics and mechanical properties of each section of the robot are analyzed. A part of resistance is transformed into active force of reconfiguration, and transforms are actualized among five specific configurations. Further, the linearization of model based on a perturbation analysis method is used to reduce the computational complexity. Finally, an evaluation criterion is proposed for AMOEBA-I＇s cooperative reconfiguration performance. The validity of the cooperative reconfiguration method is proved by simulations and experiments.

Continuous cooling transformation of under-cooled aus- tenite for Nb-V microalloyed spring steel 60Si2CrVATHua-lin Wu, Fu-ming Wang, Chang-rong Li, Qing Yan, and Bo ZhangAbstract： The continuous cooling transformation curves of under-cooled austenite in Nb-V microalloyed spring steel 60Si2CrVAT were measured by using a DIL805A quench- ing deformation dilatometer. The microstructure changes of under-cooled austenite in the tested steels at different cool- ing rates were studied by the metallographic method cou- pling with the microhardness method. The effect of Nb con- tent on continuous cooling transformation of the tested steels was analyzed. The experimental results show that with the increase in Nb content, the high-temperature and medium-temperature phase transitions were promoted,

Vol.44,No.9,2008 The end effect of empirical mode decomposition that appears when using spline interpolation to get two envelops of the data is dis- cussed.The shortage of ordinary end extending methods is pointed out.An extending method based on trigonometric functions is improved,and the influence of different extending periods,length and value of end point of the data is discussed.A comparison with mirror extending method is made and analyzed.On the basis of the improved method,a new method with exponent sine function extending approach is proposed,which decreases the envelop emanation of end points of extending data,so it can improve the speed and precision of EMD,and simulation is used to prove the effec- tiveness.Results show that the proposed improved extending method can restrain the end effect effectively.

Through the development in the past 20 years, the compliant mechanism has become an important branch of modern mechanisms and is widely applied in such fields as precision engineering and robotics. Although a series of design methods and theories of compliant mechanism have emerged, its design problem is still facing challenge. A comprehensive overview of design methods is provided for compliant mechanisms used for precision applications, usually called flexure mechanisms. Several main approaches to analysis and design of flexure mechanisms, including pseudo-rigid-body model, structural matrix model,
