Research On The Key Technology Of Wireless Micro-stimulus System For Insects

Animal robot has the advantages of high efficiency and the versatility of traditional mechanical robot,it also can make up for poor environmental adaptability and low energy utilization of the bionic robot.Besides,animal robot has high flexibility,accuracy and efficiency.So it has broad application prospects in the fields of public safety,clinical application,engineering operation and so on.So far,there have been a lot of achievements in the behavior experiment of wired control animals.But miniaturization,lightweight,low power consumption,high efficiency,and control system design with wireless communication of the animal robot is always the focus and difficulty.Based on above problems,bees are chosen as the carrier of that scheme because of their easy maintenance,small volume,group performance,strong learning capability and tested genome sequences.This paper carries out the research of wireless control system which is based on the radio frequency identification technology.And based on that research,have fulfilled the design of RFID tag antenna and lightweight stimulation system.It can achieve stable communication with the reader.The main work are as following:Firstly,miniaturized wireless control system based on radio frequency identification technology is proposed for the bee robot.Compared with other systems,that method has the advantages of small size,light weight,low power consumption and high energy utilization rate.So it can meet the needs of wireless control of small insect behavior.Secondly,a miniaturized RFID tag antenna for bee robot is proposed.During the process of design the robot hardware system,a ring structure is used to design the near field tag antenna which works in the UHF frequency band.Finally,the wireless control system which base on radio frequency identification technology is designed.The system size is 5.5mm×16.6mm×1.2mm and the weight is 175.9 mg where the power is 70 mg.The simulation results show that the center frequency of this RFID tag antenna is 920 MHz,and bandwidth is about 60 MHz under condition of S11<-10 dB.The bagpack system is able to communicate with the transmitter stably and output specific stimulus signals as required.In conclusion,this dissertation have achieved the wireless control insect robot system which is based on radio frequency identification technology.Simulation results and the test results expound that tag antenna and the stimulation system perform well and meet the requirements of miniaturization control design.
