摘要:  与科学研究、国防、警用、核电站等专用用途的移动机器人相比,应用于办公、医院、餐厅、超市等服务领域的服务机器人移动路径相对简单,行走路径以直线为主。本文采用三元阵超声波被动定位算法进行服务机器人实时定位,为了降低定位系统所需的信标数量,建立服务机器人运动模型并结合卡尔曼滤波算法进行定位轨迹后置处理,提高了较大范围内的服务机器人导航定位精度。实验结果验证了本文方法的有效性。

Abstract:  Compared with the mobile robots used in science research, defense, police, nuclear power plant and other special-purpose, the movement path of service robots used in offices, hospitals, restaurants, supermarket and other service areas is relatively simple. The main movement path of this type of robot is straight line. Three unit array ultrasonic passive localization algorithm is adopted in the real-time navigation of service robots. In order to reduce the number of beacon, we set up the service robot motion model and combine the Kalman filter algorithm to post-process the location results for better accuracy. Experimental results are provided to validity the effectiveness of the proposed navigation approach.
