The Design Of The Field Rescue Robot System

With the development of modern society,the value of human life comes more and more important.In the face of some unexpected situations in the field,due to those trapped people can not send SOS or environmental factors,rescue operations will encounter difficulties.because of unknown environmental conditions,accidents would also happen on those rescuers who get into disaster scene blindly.In order to ensure the safety of rescuers and improve the efficiency of rescue.Firstly we dispatch rescue robots to detect the environment and collect some information,at the same time,Real time information will be sent back to the rescuers so they can take the most appropriate way to help trapped people out.In this paper,author present an design of the field rescue robot system.Take FPGA as the system main controller,connect all the sensors by I/O to ensure all the smooth realization of various parts of the function.The navigation and positioning module,made up of GPS and Dead Reckoning by complementary filter,contains GPS receiver data acquisition circuit,Photoelectric encoder data acquisition circuit,Inertial sensor(ADIS16405)data acquisition circuit data acquisition circuit.Obstacle avoidance module,ultrasonic and infrared sensors are combined to avoid obstacles in a weighted manner,including corresponding circuit.Detection module,multisensor combined to obtain information,while using video capture to enhance detection.Communication module.through the wireless serial port,we can achieve the transmission of sensor data and issue a command.Motion control module can Control the movement of the rescue robot and the movement of robots' arms.Interface board module contains Sensor interface circuit,power conversion circuit,over-current protection circuit,in order to make sure,all parts can work independently without causing any mutual interference.At last the author would verify the main functions of the system.In this paper,the field rescue robot can be navigated to the specified target range.each sensor can send real-time transmission of real environmental information back to rescuers,which would can offer effective help and ensure the smooth follow-up rescue work.The field rescue robot is valuable for engineering.
