摘    要:针对自行研制的移动机器人(IMR01)设计并实现了一个分布式控制系统。IMR01采用激光雷达平台、多视觉系统作为环境感知器。利用2-D平面扫描的激光测距传感器,通过传感器平台俯仰与水平的转动实现在3-D环境感知,建立地形的高度图以分析可行区域与障碍区域。利用光纤陀螺仪、倾角仪及里程计等传感器构建移动机器人航向制导系统。控制系统基于多系统集成的低功耗工控机(IPC),在硬件上具有良好的扩展性能;通过无线网桥实现车载局域网与实验室监控系统的通讯。分布式控制系统通过异构Agent间的协作实现复杂环境下的感知与导航控制。

Abstract: A distributed control architecture was designed and implemented for a mobile robot (IMR01). Laser scanner and multi computer vision system were equipped to detect the environment. A 2-D laser rangefinder Lms291 was adopted to build terrain map through the pitch and horizontal rotation of a sensor platform. An elevation map of terrain was built and used for terrain analysis. A navigation guidance system is composed of fibre-gyro, tilt sensor and odometer. The control system comprises a multiple industrial personal computer (IPC) system with low power-consuming CPU, and has good hardware scalability. Communication between the on-board local network robot and the remote monitor system in laboratory is realized through wireless local area network. The navigation control is implemented with the cooperation among heterogeneous Agents.
