Our system focuses on domestic use for aged person who needs nursing in their daily life. Our key ideas are two topics. The first topic is combination of standing assistance function and walking assistance function. In previous works, many assistance devices are specialized in only “standing-up operation” or “walking operation”. However, in their daily life, elderly people need standing, walking and seating assistance continuously by the same device. Therefore, our developing assistance system can support both operations by a small sized mechanism which is easy to use in the home. The second topic is a seating position adjustment assistance. From questionnaires of nursing specialists, a seating position adjustment requires the elderly people to walk backward and it is difficult operation for them. Furthermore, in many cases, a failure of this operation causes a fracture which has high risk to fall into bedridden life. Thus, our developing system can assist the aged users to adjust the seating position safety. The performance of our proposed system is verified by experiments using our prototype.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133817372","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}

Rotorcraft UAVs, in particular have more challenges than its fixed wing counterparts. More research and experiments have been conducted to study the stability and control of RUAVs. A model-based control system design is particularly of our interest since it avoids a tedious trial and error process. To be able to successfully stabilize and control the RUAVs therefore a sufficiently accurate model is necessary. There are many methods in modeling small-scale rotorcraft. Using a standard first-principle based modeling approach, considerable knowledge about rotorcraft flight dynamics is required to derive the governing equation. Another method is system identification from flight data. This paper presents a method for system identification using Neural Networks. Input-output data are provided from nonlinear simulation of X-Cell 60 small scale helicopter. The data is used to train the multi-layer perceptron combined with NNARXM time regression input vector to learn nonlinear behavior of the vehicle.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115213222","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}

As a lateral control method, fuzzy control logic is developed, embedded in LACOSIM, and verified by the simulations with sine and step input errors.

In the proposed technique, genetic algorithm is used to solve the H∞ loop shaping design problem under a structure specified controller. To compare performance, conventional H∞ loop shaping, proposed robust controller and conventional ISE method are investigated. Results of simulation demonstrate the advantages of a simple structure and robustness against plant perturbations and disturbances of the proposed controller.

The robotic agents (RA) move guided by a potential field along the lanes. At the intersections an intersection agent (IA) controls the flow of traffic by assigning priorities to the agents that are about to enter the intersection. The priorities are computed based on the density of RA in a lane and the flow rate of traffic in those lanes. The RAs integrate these assigned priorities into their potential field computations. The modified potential field computations help the RAs to move through the intersection avoiding collisions. An elegant mixed autonomy scheme is thereby achieved where the IAs decide upon the priorities at the intersection while the low level collision avoidance maneuvers are left with the individual RAs. This scheme preserves the distributed nature and the autonomy of potential field maneuvers while simultaneously balancing the computation load between the IA and RAs. We compare this method with a method where the RAs navigate the intersection without a superior direction from the IAs through priorities or when IAs direct the RAs based on priorities computed on a first come first served basis. We show performance gain over both these methods in simulations.","PeriodicalId":321332,"journal":{"name":"2008 IEEE International Conference on Robotics and Biomimetics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115845174","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}
