Design of laboratory intelligent fume hood based on truncated continuous vortex ring wind curtain technology

Abstract

In recent years, with the continuous exploration of marine resources, the research of underwater robot has been paid more and more attention. Starting from the development history of underwater robots, this paper introduces the research status and problems to be solved of existing underwater robots, and independently designs an underwater automatic depth determination intelligent robot according to various needs. Through the sealing structure design based on sealing chamber and O-ring, the good water tightness and safety of the device are ensured; The system is equipped with Jetson nano embedded platform, on which relevant programs based on PID control algorithm and yolov5 recognition algorithm are written to ensure that the robot can complete the specified tasks underwater; The underwater robot system uses gyroscope, electronic compass mhr3500, camera and other relevant sensors to collect the relevant motion data of the device, and can feed back the data to the main control board. The main control board matches the corresponding output to the horizontal and vertical propellers according to the relevant algorithm, so that the robot can move at any height; The system uses the combination of software and hardware to ensure the stability of the device during operation.
