Research and development of picking robot interactive terminal based on WIFI digital image transmission

摘要:

在一些特殊的采摘作业场合,如复杂的山地、悬崖等作业危险性较高的地区,研究一款双向通信的机器人,一方面可以传回复杂环境的作业信息,另一方面可以通过控制中心发出控制指令,指导机器人在复杂环境中完成采摘作业,具有重要的现实意义。为此,基于WIFI无线局域网,提出了一种具有实时数字图像传输的交互终端式采摘机器人,采用高清COMS相机完成图像的采集,使用MCU处理器对图像和控制信号进行处理,利用WIFI模型完成图像和控制信号的传送。为了验证方案的可行性,分别对监控端和机器人接收端的通信进行了测试。测试结果表明:采摘机器人采用WIFI无线通信,其通信速度和通信距离相比其他无线通信方式都具有明显的优势,可以有效完成数字图像的传送。对接收终端和采摘终端的双向通信误码率进行了统计,统计结果表明:其通信的精度较高,可以满足复杂环境采摘作业的设计需求。

Abstract:

In some special picking jobs, such as complex mountains, cliffs and other high-risk areas, the study of a two-way communication robot, on the one hand can return complex operating information, on the other hand can be issued through the control center Control instructions to guide the robot in the complex environment to complete the picking operation, has important practical significance. Therefore, based on the WIFI wireless local area network, an interactive terminal picking robot with real-time digital image transmission is proposed. The image is acquired with an HD CMOS camera. The MCU and processor are used to process the image and control signals. The WIFI model is used to complete the image And control signal transmission. In order to verify the feasibility of the scheme, the communication between the monitoring terminal and the robot receiving terminal was tested respectively. The test results show that: Picking robot using WIFI wireless communication, the communication speed and communication distance compared to other wireless communication methods have obvious advantages, can effectively complete the digital image transmission. The bit error rate of two-way communication between the receiving terminal and the picking terminal is statistically analyzed. The statistical results show that the communication precision is high, which can meet the design requirements of the picking operation in complex environment.
