基于嵌入式系统的移动机器人无线远程控制系统设计

摘要

A suit of robot wireless remote control system was set up using the ? IIA mobile robot as the controlled object. The wireless local area network was built. The hardware structure and software structure of the system were designed. The improved Elman network was used to forecast the utilization ratio of network bandwidth to solve the contradiction between narrow band and a large quantity of data in the transmission. At the same time, the sending rate of video stream was adjusted according to the predictable results. The experimental results demonstrate using the method, control performance of the wireless remote control system is improved.%以旅行家TMIIA机器人为被控对象,建立一套机器人无线远程控制系统,搭建无线局域网,设计机器人远程控制系统的硬件和软件结构；针对目前无线网络传输带宽窄与传输数据量大的矛盾,提出采用改进的Elman网络去预测网络带宽利用率,并根据预测结果调节视频数据流的发送速率.实验结果表明,该方法在很大程度上改善了移动机器人无线远程控制系统的控制性能.
