Electronics Competitions


Intelligent Car Competition(2019):


Intelligent Car Competition is one of the most famous undergraduate technology competitions in China. The primary task of the intelligent car competition is to recognize the race track and complete the specified tasks as quickly as possible. These tasks include navigating through the roundabout, avoiding obstacles, and transitioning between two-wheel upright and three-wheel states when encountering gaps in the track.
Please note that since there are no official competition videos available, we are using laboratory test videos for reference.

Electronics Design Competition (2019):


Electronics design competition is a time-constrained challenge, where all participants are required to rapidly prototype based on the given tasks over the course of four days and three nights. Scores are calculated based on the completion of tasks. I led a team that achieved a top 10% nationwide ranking.

This electromagnetic railgun, designed for simulation purposes, utilizes the RT1021 core board as its control center and is composed of a system that includes a booster module, servos, a camera, a gimbal, coils, and supercapacitors. The microcontroller outputs variable PWM waves to the servos to control the angle, facilitating the gimbal's horizontal and pitch movements. With the camera module, it accurately measures the difference between the center of the target and the center of the camera image and provides feedback to the microcontroller to ensure timely correction by the servos, keeping the weapon aimed at the target. Based on the distance from the target center to the railgun (input manually or measured using time-of-flight or pixel-based camera methods), it outputs a linear voltage to control the DC power supply for charging the supercapacitors. The supercapacitors discharge through the coils, generating a powerful magnetic field that propels a small magnet inside the tube along a parabolic trajectory, hitting the target dead center. This design controls the launch distance by adjusting the charging voltage.
