为了检测水下机器人在海里位姿状态变化的问题,研究了基于陀螺仪的水下机器人位姿测量系统。系统由水下机器人、Arduino UNO控制板、MPU6050陀螺仪和USB-TTL转换元件组成,采用Arduino UNO作为系统控制器。通过MPU6050陀螺仪采集水下机器人位姿信息,经过Arduino UNO控制器的信息处理,以及USB-TTL转换元件的信号转换和传输,经MiniIMU上位机的数据显示,通过对数字信号进行严密的数学推算,最终实现对水下机器人位姿的测量并通过上位机对水下机器人位姿进行动态显示。 相似文献

□ A novel self-determination polishing robot finishing large mold free-form surface is developed, and the finishing process method is researched. Contrary to traditional approaches, our premise is that a large mold surface can be polished by using a small robot. This robot system is mainly composed of a polishing robot part, a computer system and a visual positioning system. A type of robot with four uniform distribution wheels was designed, which has two driving wheels and two driven wheels. Active compliant control of the polishing tool was provided by a pneumatic servo system, and a new special compliant abrasive tool was proposed on the basis of robot characteristics. The process planning steps consisted of subdividing the free-form surface, choosing an abrasive tool, planning the polishing path and optimizing machining parameters. Based on the orthogonal experiment and the grey relational analysis method, the optimal parameter combination was obtained for polishing force, tool speed and feed rate. Aiming to polishing times, the surface roughness method and polishing efficiency method were studied in detail. The polishing experiments were carried out in the robot using process parameters obtained by the efficiency method. These research results provided significant theory foundation and experimental data for a mobile robot planning polishing to realize intelligible process parameter selection. 相似文献
