The system enables the realization of the point-by-point measurements of the sound intensity field and consists of 3 main blocks realised in LabVIEW environment: positioning system control, multichannel data acquisition and signal processing. This hardware-software solution allows the determination of the spatial vector distribution of sound intensity. To estimate sound intensity vector at each measurement point in space, sound pressure scalar and three component (x, y, z) of sound particle velocity (3D) vector must be measured. It is done using the condenser microphone coupled with 3D Microflown hot wire anemometry USP type sensor. The system controls positioning of the measuring probe in sequential points, acquires 4 data channels (pressure and 3 velocity components) and processes the data to obtain the sound intensity values in each measuring points. All the computation needed is done in real-time.","PeriodicalId":440376,"journal":{"name":"2011 16th International Conference on Methods & Models in Automation & Robotics","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128628437","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 proposed method extends a classical 2D dead reckoning system to a 3D pose estimation system by merging data from odometry and multiple low cost rate gyros and accelerometers. The localization problem is decomposed into two parts, i.e. attitude estimation followed by pose estimation. Based on the innovation sequence, the pitch and roll angles are estimated by an R-adaptive Kalman filter. The adaptive filter is initialized with the maximum measurement noise level resulting from non-gravitational acceleration. Based on the discrepancy between the theoretical and the actual innovation covariance, the measurement covariance R is adjusted by applying a scalar gain for each time step. Heading is calculated based on the gyrodometry algorithm. Finally, the attitude information is fused with data coming from the wheel encoders in order to estimate the 3D position of the robotic walker. Experimental results to investigate the performance of the proposed adaptive Kalman filter and the 3D localization system are presented.","PeriodicalId":440376,"journal":{"name":"2011 16th International Conference on Methods & Models in Automation & Robotics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130259707","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}

In the considered systems the stock used to fulfill unknown, variable demand deteriorates exponentially, and is replenished with delay from several supply sources. The supply options are characterized by different lead times, spanning multiple review periods. We develop a new supply policy based on discrete-time sliding-mode (DSM) control. The proposed DSM controller with the sliding plane selected for a dead-beat scheme ensures the maximum service level with smaller holding costs and smoother ordering signal as compared to the classical order-up-to policy.","PeriodicalId":440376,"journal":{"name":"2011 16th International Conference on Methods & Models in Automation & Robotics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125387133","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}

In order to operate optimally during performance of any operations, a mobile robot must understand the effects of its own dynamic model and interactions with the track. Propulsion system should be optimised to withstand environmental conditions and acquire precise motion control. Additionally, during the design process, it is required to consider limitation of accessible control platforms and systems. Therefore, it is natural to implement control algorithms to achieve prescribed optimal motion and immune system for imperfectness of the model, trajectory disturbances and electronics limitations.","PeriodicalId":440376,"journal":{"name":"2011 16th International Conference on Methods & Models in Automation & Robotics","volume":"2018 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121518789","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}

EKF-SLAM is considered as a classical method to solve SLAM problem. This method, however, suffers from two major issues; the quadratic computational complexity and single hypothesis data association. Large number of landmarks in the environment, especially, nearby landmarks, causes extensive error accumulation when the robot is traveling along a desired path. The multi-hypothesis data association property and the linear computational complexity are essential features in FastSLAM method. Those features make this method an alternative to overcome mentioned issues. The FastSLAM algorithm uses Rao-Blackwellised particle filtering to estimate the path of the robot and EKF-SLAM method to estimate locations of landmarks. In case of FastSLAM applications, however, observation noise needs to be reconsidered if the motion measurements are noisy while the range sensor is noiseless. This study suggests optimization of a specific situation of FastSLAM algorithm in case of noise discrepancy.","PeriodicalId":440376,"journal":{"name":"2011 16th International Conference on Methods & Models in Automation & Robotics","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121754893","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 existing system, based on a network of fixed Border Guard posts and routine patrols of Border Guard officers becomes obsolete and inadequate to counter present-day threats and in addition is economically inefficient. The TALOS system introduces fully autonomous robotic craft, able to perform routine patrols and react to typical situations without constant human supervision. Such robots operate from a fully mobile base, which can be transported and deployed at any place along the EU land border in a matter of hours. Therefore, the robotic component of a border protection system is expected to be a remedy against its current main disadvantages, which are its static nature and predictability. Moreover, an increase in economic efficiency and personal safety of Border Guard officers is also expected.","PeriodicalId":440376,"journal":{"name":"2011 16th International Conference on Methods & Models in Automation & Robotics","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132807285","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}
