RoboCup Strategy AI

Overview

The RoboCup Strategy AI system was built to handle the complex problem of multi-robot coordination in a fast-paced, dynamic environment. The system processes real-time vision data from multiple cameras, maintains a world model of all robots and the ball, and makes strategic decisions about robot movements and actions. The AI uses a hierarchical approach with high-level strategy planning and low-level motion control, allowing the team to respond to changing game conditions within milliseconds.

Architecture

The system is built with a modular architecture consisting of several key components: a vision processing pipeline that ingests camera feeds and outputs object positions, a world state maintainer that fuses multi-camera data and tracks object velocities, a strategy planner that evaluates game situations and decides on tactics, and a motion controller that translates high-level strategies into individual robot commands. The entire system runs on ROS2 for inter-process communication and uses OpenCV for vision tasks. Communication with robots happens via UDP at 60Hz update rate.
