Abstract

This paper presents an experimental mobile robot designed to operate autonomously within both indoor and outdoor environments. A sensor-based autonomous navigation architecture for a dynamically changing environment is described. Emphasis is placed on two important issues: autonomous navigation and smooth guidance of the robot. Several trajectory models are adopted to generate continuous-curvature paths in order to cope with the nonholonomic constraint of the robot and unexpected obstacles. A smooth guidance algorithm has been used to track the planned path. Experimental results demonstrate its performance.

智能移动机器人的导航与制导
本文提出了一种实验性的可在室内和室外环境中自主操作的移动机器人。针对动态变化环境,提出了一种基于传感器的自主导航体系结构。重点研究了机器人的自主导航和平滑制导两个重要问题。为了应对机器人的非完整约束和意外障碍物,采用多种轨迹模型生成连续曲率路径。采用平滑制导算法对规划路径进行跟踪。实验结果证明了该方法的有效性。
