Design of dead reckoning system for mobile robot 总被引:2,自引:0,他引:2
A dead reckoning system for a wheeled mobile robot was designed, and the method for robot's pose estimation in the 3D environments was presented on the basis of its rigid-body kinematic equations. After analyzing the locomotion architecture of mobile robot and the principle of proprioceptive sensors, the kinematics model of mobile robot was built to realize the relative localization. Considering that the research on dead reckoning of mobile robot was confined to the 2 dimensional planes, the locomotion of mobile robot in the 3 coordinate axis direction was thought over in order to estimate its pose on uneven terrain. Because the computing method in a plane is rather mature, the calculation in height direction is emphatically represented as a key issue. With experimental results obtained by simulation program and robot platform, the position of mobile robot can be reliably estimated and the localization precision can be effectively improved, so the effectiveness of this dead reckoning system is demonstrated. 相似文献

An adaptive particle filter for mobile robot fault diagnosis 总被引:2,自引:2,他引:2
An adaptive particle filter for fault diagnosis of dead-reckoning system was presented, which applied a general framework to integrate rule-based domain knowledge into particle filter. Domain knowledge was exploited to constrain the state space to certain subset. The state space was adjusted by setting the transition matrix. Firstly, the monitored mobile robot and its kinematics models, measurement models and fault models were given. Then, 5 kinds of planar movement states of the robot were estimated with driving speeds of left and right Side. After that, the possible (or detectable) fault modes were obtained to modify the transitional probability. There are two typical advantages of this method, i.e. particles will never be drawn from hopeless area of the state space, and the particle number is reduced. 相似文献

针对可追踪属性基加密方案利用追踪功能解决密钥委托滥用问题的不完备性,提出了一种抗密钥委托滥用的可追踪属性基加密方案。将秘密参数分享给用户私钥中关联属性的全部组件,使解密过程必须由全部组件共同参与完成,仅由用户私钥的一部分不能进行解密操作,从而实现真正的抗密钥委托滥用。利用一种短签名技术保护用户私钥中的追踪参数,防止追踪参数被伪造,从而获得对用户的追踪能力。同时支持抗密钥委托滥用和可追踪增强了所提方案的安全性。与相关方案的对比分析表明,所提方案在参数尺寸和计算代价上具有更好的性能优势。 相似文献
