ROBOCON 2023 China National Contest

Project Details

The task was to design a fully autonomous volleyball robot capable of performing target detection, trajectory prediction, and receiving tasks.

My Role

I was primarily responsible for the robot’s visual perception and prediction algorithms:

  1. Spatio-temporal Data Fusion: Fused binocular depth information from an Intel Realsense D455 with pixel-level data from YOLOv5 to calculate the precise 3D spatio-temporal sequence (X, Y, Z, t) of the volleyball.

  2. Trajectory Prediction: Utilized the acquired spatio-temporal sequence to perform real-time trajectory fitting and prediction using the Least Squares method, assisting the robot’s decision-making system in receiving the ball.
