This paper presents a type of low speed and high torque motor ——a double meshing motor with new structure and new principle integrating the reduction gear which can be applied in robot joint and meets the need of space endurance and space fitness of robot. Compared with conventional motors, the noticeable features of this motor are short drive chain, high respond speed, stability at low speed, big output torque. For the reason of using two rotors, the eccentric force and operation vibration induced by the eccentric motion of rotors can be balanced and decreased efficiently. Additionally, the operation principle and mechanism characteristics of this new motor are introduced, and a solid model is designed. As for the control method, it is simple and same as the switched reluctance motor. The magnetic circuit model of this motor is established, and this model is applied to analysis the features of motor as well as the finite element analysis is also figured out. The coenergy principle is used to calculate the starting torque of the motor. For verifying the calculation, the results of finite element analysis is adopted to compare with the results calculated by magnetic coenergy method. Based on these results of calculation and finite element analysis simulation, the double meshing motor has higher torque and lower speed compare with the conventional motor has the same volume; it is evident that the double meshing gear motor has application prospect and practical value.","PeriodicalId":320307,"journal":{"name":"2009 International Asia Conference on Informatics in Control, Automation and Robotics","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122172282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating the model-based system and the behavior-based system, a hybrid distributed control system is established, which emphasizes on the autonomy and intelligence of each robot. On the one hand, the algorithm uses artificial potential field for multi-robot formation. On the other hand, the limit-cycle based algorithm is introduced to enable the robot team to pursue themoving target and ultimately encircle the target in a symmetrical circle formation. In addition, the paper designs a heading direction control law for obstacle avoidance, and solves the problem of robot freezing caused by counteraction between repulsion and attraction. Simulation results show the effectiveness and reliability of the proposed method in cooperative hunting control.","PeriodicalId":320307,"journal":{"name":"2009 International Asia Conference on Informatics in Control, Automation and Robotics","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114822231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RCP as a live design can realize a smooth and fast transition from conceptual design to experimental verifications.

This paper discussed the dynamic nature of urban intersections, and presents a novel traffic flow evolution model at a time scale and of a level of detail suitable for on-line estimation, simulation and control. The intersection is considered as interconnected components of urban road network. The macroscopic model proposed here extends the platoon-dispersion model by redefining inflow and outflow vectors, and by also specifying the control vector. Two variables were added to the model, i.e. the turning proportion and the lane assignment scheme. The turning proportion is an obvious variant, and yet the lane assignment is time-varying in some especial condition. Simple stochastic matrix equations described the macroscopic traffic behavior of each movement. This will allow the simulation of quite large road networks by composing many intersection models. The model is validated over real traffic data with abrupt changes in the demand of flow.","PeriodicalId":320307,"journal":{"name":"2009 International Asia Conference on Informatics in Control, Automation and Robotics","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123509746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel kind of sensorless rapid on-line evaluation technology for machine tool slide level based on linear or rotary scale, motor encoder and AC servo motor current/output torque is proposed. To acquire the level information, the sensorless test principle is profoundly investigated, and the relationship mathematical model between the slide level and the sensorless data is established. Furthermore, according to the Stribeck effect, the various amplitude and velocity triangular wave test curve and a kind of precise nonlinear model identification method are suggested to get the key parameters such as static friction torque, coulomb friction torque, viscous coefficient and total moment of inertia. And then CNC slide level can be identified.

With the help of that the efficiency of the fuzzy logic controller is improved significantly which is also employed to calculate the speed of the robot.

The intelligent pneumatic muscle (IPM) with shape memory alloy (SMA) wires braided shell was proposed to improve characteristics. The mechanism was designed and prototype test-bench was made. Output force model was established through static force equilibrium analysis. The equation between temperature and contraction ratio of SMA wires was deduced through analyzing the volume ratio of Martensite to Austenite during crystalline structure transformation. This equation was adopted to get calculating methods of the contraction ratio, contractile force per cross-section area and variable stiffness of intelligent pneumatic muscle. Characteristics simulation was done on MATLAB and different pneumatic muscles’ characteristics were compared. The results show IPM has greater shell braided angle, greater contractile force and more flexible stiffness through adjusting SMA contraction ratio.","PeriodicalId":320307,"journal":{"name":"2009 International Asia Conference on Informatics in Control, Automation and Robotics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129960908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
