As one part of the project, the dissertation is developed with thelocalization problem in mobile robot navigation. Combined with "MobileRobot 1 of Central South university (MORCS-1)", a mobile robot designed byus that equipped with a 2D laser measurement system to sense the environmentand the proprioceptive sensors such as the odometry, gyroscope to calculate itsdead reckoning, the approach about the four kind uncertainty factors of mobilerobot localization is studied. These researches include that the error analysisand calibration of position sensors is implemented to reduce the measurementnoise, the 3D kinematic model of mobile robot is built to gain the accuratepose in complex terrain, some work on the automatic detection of static ordynamic obstacles based on laser scanner is investigated to eliminate thedynamic influence of the environment and to realize the reliably absoluteposition, and lastly a robust algorithm is presented to involve the incrementalenvironment mapping and self-localization of mobile robot with unknown dataassociation and to improve the self-localization performance of mobile robotunder unknown environment.

Healthy volunteers participated 6 experiments that were designed to test the sensory conflict theory of motion sickness, to observe the effect of the outside proprioceptive input on motion sickness and to make sure the influence of motion sickness susceptibility, automatic nerve activity and breed on experimental nausea and vomiting. The results were as follows: 1. Different intensity of visual and vestibular sensory conflict effected the onset of vection and rotation toleration time and the symptoms of nausea and vomiting, the more intensive of confliction, the more quickly onset of vection, the more short rotation toleration time, and the more serious symptoms of nausea and vomiting.
本研究针对上述问题设计了6个实验,以200名健康成年志愿者为被试,以转椅和转鼓作为诱发实验性晕动的装置,采用恶心评定量表、恶心问卷和晕动敏感史量表及自我运动错觉和旋转耐受时间为指标,旨在考察:(1)实验性恶心、呕吐症状的时间变化规律;(2)不同强度感觉冲突、不同体位因素对实验性恶心、呕吐的影响,验证晕动的理论假设;(3)晕动敏感史差异、人格因素、种族因素与实验性恶心、呕吐的关系。

So, the study in this dissertation focuses on some key points in theuncertainty treatment of mobile robot localization as follows: Combined with the multiple proprioceptive and exteroceptive sensors ofmobile robot MORCS-1, aimed at the drift error of fiber optic gyro as theproprioceptive sensor, the neural network using genetic algorithm as optimaltool is proposed to accomplish the modeling and calibration for temperaturedrift of fiber optic gyro, which can reduce the drift error to the standard outputat constant temperature; and aimed at the noisy disturbance of ranging datafrom the exteroceptive sensor laser scanner, a dynamic adaptive filter isintroduced through the analysis of neighboring ranging data in time and spatialcorrelation to realize the real-time and dynamic filter, which can validly filter the noisy disturbance to meet the requirement of the accurately real-timeobstacle detection in mobile robot navigation.
