一种小型智能水上救援机器人的设计

The Design of a Small Intelligent Robot for Water Rescue

针对水上救援设备操作复杂、体积大、不易收纳、对操作人员专业要求高等问题,设计了一款适用城市环境、能实现快速救援的小型水上救援机器人。机器人以树莓派Raspberry Pi 3B为主控模块,结合避障模块和热成像模块,通过YOLO算法视觉识别技术、2.4 GHz无线通信技术、TDOA(Time Difference of Arrival,到达时间差,简称TDOA)无线定位算法,实现了救援机器人的远程遥控辅助功能、智能识别溺水者功能、自主避障功能、弹射功能和智能终端显示功能,试验验证了机器人的稳定性和可靠性。

A small robot for water rescue appliable to urban environment and capable of rapid rescue was designed so as to solve the problems found in the rescue devices available on the market such as complex operation,bulkiness,difficulty in storage and enormous demands on professional operators. With the master control Raspberry Pi 3B,the obstacle avoidance module and the thermal imaging module,the robot stably and reliably completed the functions of remote control, intelligent identification of drowning victims,independent avoidance of obstacles,ejection and information display on intelligent terminal as well through YOLO algorithm for object detection,2.4 GHz wireless transmission technology and TDOA(Time Difference of Arrival) algorithm,which has been tested and verified.
