However, these networks are extremely vulnerable to disaster or attack in emergency situations. Therefore, how to maintain communication link under emergency situations is very important. In this paper, we utilize a series of autonomous mobile slave robots which follow behind the lead robot and automatically stop where needed to maintain an ad hoc network for guaranteeing a link between the lead robot and its remote monitor/control station. To accomplish this target, an efficient communication protocol limitation mobile robots broadcast based on AODV (LMRB-AODV) is proposed for deployment in multi-robot system. After then the lead robot could carry service traffics to the monitor station under emergency situations through the communication link. At any instance, the lead robot has the ability to reclaim the relay robot(s) which are unneeded in the network to rejoin the convoy behind the lead robot and use it to extend the range of wireless communication when the radio frequency (RF) shortcuts are detected by the lead robot. All relay deployment and reclaiming strategy functions occur without the operator's involvement. Finally, we provide a comparative study of their performance in a number of different simulation environments. The results show that the proposed scheme is very efficient in maintaining communication link in wireless network.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131984510","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}

The study is adopting a method with optics to detect data not electronics, because it can avoid the disturbance which is brought by the electric charge. Based on the basic principles of SPR, we assembled a mini-SPR equipment, and it has the accuracy fitting for our works. To adjust the angle of the polarizer and move the fiber, we can make the spectrogram that membrane is coupled on the surface of the gold slice. Comparing to the reference spectrogram, we can make a certain relationship between the light absorbed maximum and the quality of the phospholipid molecules coupling on the surface. It can token the resident time with the time which the detected spectrogram resumes to the reference one. And the resonance angle has a definite shift. We can assess the stability of phospholipid BLM with the three references. The mini-SPR equipment can easily change the parts and the parameter with the up-and-down equipment, the movement of the fiber and replacing the triangular prism plated the thin metal.

The generic part of the Service-Adaptive Engine (that is, the part that is independent of the specific types you have defined in MIDL) is accessed through the SL API.

When many objects scattering on the table in workspace, if the robot want to grasp only one object, the robot system should has a path planning to approach the object. In this case, the obstacle representation in cluttered-environment is an important role for robot system. The research area of 3D workspace modeling, the research of step by step accumulating environment observation method is more difficult than the entire environment observing method and the research is not reported sufficiently. In this paper, we can contribute the two issues for real-time 3D workspace modeling to using the sequential input stereopsis scenes information. First, we can suggest a method to estimate the transformation matrix from using SIFT feature and Epipolar Geometry Constraint characteristics in the continuous process of accumulating sequential input stereopsis scenes for more fast and accurate than recently research. This method guarantees a feasible transformation matrix result better than the using traditional ICP and general SIFT method. Second, we can suggest a method for octree-based obstacle representation and we can also suggest an octree update method for real-time. It is faster than entire workspace observation method, and if the robot doesn't know about the objects and obstacles information in workspace, we can help the robot to understand environment himself from practical information. Taking the obstacle information from above method can help the robot system possible to do path planning for robotic manipulation task in 3D workspace. Through the experimental result, we can show that our method is well-performing and well-modeling the obstacle in 3D real environment workspace modeling in real-time.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129391063","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}
