This paper proposes multi-sensor localization framework for an autonomous mobile robot using multiple sensor. To realize robust localization in outdoor environments, many external sensors are needed. The propoesd localization framework in the paper is to divide the localization system into modules that contains retro-active localization function for particle filter to solve computation delay of to calculate measurement models. In this paper, solutions for multi-sensor localization are illustrated and localization experimental results in outdoor environments are described.

We had developed the 3D shape measurement method using the robot technology to measure underground pipes.And we got the rough shapes of pipe. Our new aim is the accuracy improvement of the 3D shape measurement.Gyroscope on the robot is used to estimate robot position.Hence the specification of gyroscope is greatly related to accuracy of measurement.In this paper, to improve the accuracy of measurement, we propose a method to choose a gyroscope which can satisfy the target accuracy. We evaluated the measurement error caused by specification of gyroscope by simulation, and we found the index of specification of gyroscope.

Search and rescue (SAR) dogs show the typical motions when they find victims. The authors aimed to develop the measurement methods of the SAR dog's motions which suggest the victim locations. It can be used for making investigation maps with victim locations. The authors focused on barking and tail's wagging, and digging as the motion. We used IMU for measurement. The sensors were put on the vest for dogs, and We use no additional clothes by preference. We evaluated their locations and whether it is possible to detect the motions. For example, we can detect wagging motion by IMU directly on the tail.

In our study, we developed AED Gripping System for AED transport UAV in order to deliver quickly to remote places. This system is structured by grippers and a gripping determination system. We introduced Permanent Electromagnets as gripper. The gripping determination system is necessary to confirm that the AED is delivered at the destination, because AED transport UAV flies to remote places which the pilot cannot see the UAV. We developed a new gripping determination system which use the difference of convergence time of counter-electromotive force between gripping or not. We conducted flight experiments and confirmed that the AED Gripping System do not drop the AED accidentally and can confirm gripping status during flight.

This paper describes method to improve the accuracy of localization of mobile robot using GPS with particle filter. This method improves the accuracy of localization by removing multipath of GPS measurement data with 3D-Map. This approach analyzes area that cannot receive direct wave from GPS satellite with 3D-Map about each satellite. The particles in that area are assumed to be receiving GPS data including the multipath error. And particle's likelihood is calculated considering the multipath error. This method is useful for localization and navigation of mobile robot between buildings.

著者はGlobal Positioning System(GPS)を用いた自律移動ロボットの屋外ナビゲーションのための測位手法の開発を行った。本論分では最初に,1.GPSとオドメトリを用いたナビゲーションのための測位手法を提案し,提案手法を実際の移動ロボットに実装し屋外環境でナビゲーション実験を行い,提案手法の有効性を示す。この測位手法を開発する際の技術的な課題は,測位誤差を含むGPS測位値から誤差の小さな測位値を選び出し,かつGPS測位値の誤差を考慮して位置修正に使用することである。著者はこの問題を,a.オドメオリを基準にGPSn測位誤差を判定し,弁別されたGPS測位地とオドメトリを拡張カルマンフィルタの枠組みを用いて融合する手法を開発することで解決した。この提案手法は実験の結果,非常に正室の良い処理であることが確認できたが,高い建物や樹木の付近で測位の制度が低くなるという問題が判明した。 ・・・

Our research objective is localization and mapping for rescue crawler robot in unknown environment. The problem is well known as SLAM problem. For solving the problem, the robot position and environment shape are measured by odometry and LRF respectively. Odometry's error is corrected by matching these shape data. Map is constructed from these shapes and the modified robot position. However, odometry can not be used for measurement of our crawler robot's position because the crawler has crawlers and wheels as locomotion. In this paper, the authors present our approach for measurement of its position and construction of the map. Concretely, the authors measure its position by matching 2D scan data measured at different points. Moreover, we correct the scan's distortion caused by robot movement.
