摘要: 介绍了矿井救灾机器人自主定位系统的构成和基于航迹推算的自主定位方法,提出了改进的自主定位方法,即使用具备衰减指数因子的有限记忆卡尔曼方法,并以逐级滤波的方式融合多传感器信息。Matlab仿真结果表明,该方法可以稳定地实现0.5 m的跟踪精度;通过实体机器人实验验证了本文提出的矿井救灾机器人自主定位方法的有效性。Abstract: Components of self-localization system of mine rescue robots was introduced, self-localization method based on dead reckoning was introduced and improved. The improved method uses limited memory Kalman filter with exponential fading factor, and fuses data of multiple sensors in a stepwise manner. The Matlab simulation results show that the improved method can stably achieve tracking accuracy of 0.5 m. Experiments on mine rescue robot entity were carried out to justify the validity of the proposed self-localization method of mine rescue robot.
