Research On Key Technology Of Miniaturized Main Control System Of Biological Robot

Biological robots are a combination of electronic equipment and living things.Research on biological robots can apply external stimuli through electronic devices on the basis of preserving their own habits,so that they can act according to humans subjective wishes and help humans complete special tasks.This paper takes domestic pigeons as the research object,and designs a set of miniaturized master control systems for biological robots,including:(1)Propose a multi-dimensional information fusion control method.Based on the habits of domestic pigeons,combined with the daily life of domestic pigeons and environmental factors such as weather and seasons,the scope of control decisions is given.Strengthen the controlled flight of domestic pigeons through behavior training and reward and punishment mechanism.Based on the daily behavior and current posture of the domestic pigeon,avoid imposing stimulation on the domestic pigeon that cannot be achieved under normal circumstances.Combining the real-time geographic location of the pigeon and the expected flight route,the position error is calculated,and the stimulus intensity is changed by proportional control based on the error,so that the pigeon can fly to the target location according to the desired route.(2)Design and realize a set of miniature master control device of domestic pigeon biological robot.The stimulating current is used in conjunction with implanted microelectrodes deep into the nucleus region of the pigeon's brain to control the direction of the pigeon's movement.Reserve the optical excitation interface for optogenetic experiments.Collect and display the current posture information of the pigeon in real time.Combined with the map,it realizes the remote positioning of the domestic pigeon and the drawing of the flight trajectory.Use 4G communication and cloud server to perform remote behavior control and flight status detection of domestic pigeons.Based on gallium arsenide solar panels,combined with the high-efficiency solar charging circuit and the low-power design of the main control system,it supports the equipment to work for a long time in the field.The multi-layer board design and a special backpack are used to enhance the wearability of the device,so that the pigeon will not affect its normal behavior after being worn.(3)Design and implement a set of domestic pigeon neural signal acquisition system.It supports up to 16 channels of neural signal high-speed acquisition,and uses WIFI communication based on TCP protocol to transmit to the host computer software and display multi-channel data in real time.The acquisition system has sleep and network reconnection functions.The whole set of neural signal acquisition system provides experimental support for neural signal feature extraction in the future.
