Work History

fishbot 2-wheel Differential Vehicle

04.2024 - 05.2024
  • Using ROS2 in Ubuntu, ESP32 and ESP8266 are used as the main control board of the car and the main control board of the radar to realize the two-wheeled differential car control
  • The IMU is controlled through I2C protocol to get the position coordinates of the trolley and the acceleration in x,y,z axes
  • Deploy open source cartographer algorithm and navigation algorithm to map floors by lidar and simulate cart navigation in rviz2 and gazebo
  • Through Wifi communication and PID algorithm, it realizes the computer keyboard to control the cart forward and backward, accelerate and decelerate, and turn left and right
  • Indirectly get the speed of the cart by calculating the encoder pulse
  • Personal gain: learn the steps of building and navigating through rviz2 in Ubuntu, and understand the process of ROS2 development

Wireless Blood Pressure Monitoring Device Based on Photoelectric Pulse Wave

10.2023 - 04.2024
  • To design a measurement platform for blood pressure prediction through ECG and pulse wave signals, to realize the measurement of the time difference between the transmission of pulse wave and ECG signals, and to predict blood pressure through linear regression model
  • The signal is transmitted through STM32 using UART and Bluetooth module; Matlab is used to reduce the signal baseline drift to 20%, extract the eigenvalues such as extreme values
  • Waveform reconstruction of MIMIC database pulse wave signals using tensorflow deep learning framework in python to predict blood pressure, systolic, diastolic and mean
  • The mean value of the error between arterial pressure and the true value is less than 2 mmHg, and the standard deviation is less than 11 mmHg
  • Personal gain: learn how to download data via Linux commands in Ubuntu, and gain knowledge of image segmentation algorithms such as U-Net

Embedded Software Intern

Tsinghua University Shenzhen Research Institute
07.2023 - 08.2023
  • Flowmeter Data Display Module Utilizes STM32F103RCT6 to implement SD card file processing, OLED picture display and serial communication data
  • Print SD card file list, create file and read file content on serial tool through FATFS file system; use UART protocol to send and receive data
  • Use Image2LCD for image modeling to convert BMP files into C language arrays for display via RGB565 display
  • Creating queue set tasks for pinball game and cart game with FreeRTOS
  • Personal gains: learning through Keil to STM32 according to the demand for development, mastered the word mode conversion software and picture mode software, realize the flow meter screen display
