中文摘要: 多机器人协作实时同时定位与地图创建(SLAM)技术可以解决单机器人实时SLAM的自身定位误差累积问题和路标数据关联问题,并减少对大量传感器的依赖,提高系统的可靠性,但同时面临个体不完全量测和通信局限下的信息局部性、多样性和滞后性等问题。信息和信息引起的控制的不一致性成为制约多机器人协作实时SLAM技术发展和应用的瓶颈问题。本课题在项目组前期的研究基础上,以实际工程应用为目标,重点研究:不完全量测下的个体信息一致性问题,通信局限下的个体信息一致性问题,机器人协作行为执行的一致性问题,多机器人实时建图的地图一致性问题,并在此基础上建立多机器人协作实时SLAM的一致性性能评价准则。本项目研究结果适用于其他多机器人协作技术领域,将进一步完善和丰富多机器人协作理论,研究结果将应用于城市反恐和特种侦察作战条件下多机器人侦察系统。

英文摘要: Multi-robots cooperative online simultaneous localization and mapping(SLAM) technology can solve single robot online SLAM positioning error accumulated problems and landmarks data association problems. The dependency of a large number of sensors is reduced and the reliability of the system is improved. But at the same time some problems are coming: such as individual intermittent observations, information locality, diversity and lag with communication limitations. The inconsistency of information and control caused by information becomes a bottleneck of the constraints of multi-robots cooperative online SLAM technology development and application. The subject, on the basis of the project team pre-study, on the target of practical engineering applications, focuses on: individual information consistency problem with intermittent observations, individual information consistency problem with communication limitations, control behavior consistency problem of multi-robots cooperation, map consistency problem of multi-robots online mapping. The consistency evaluation criteria will be established on the basis of above research in multi-robots cooperative online SLAM. The project is applicable to other multi-robots cooperative technology, and will further improve and enrich multi-robots cooperative theory. The research r
