About the Competition
What is KRSBU UNLIMITED 2026?
KRSBU (UNLIMITED Wheeled Robot Competition) is a wheeled soccer-robot challenge adapted from RoboCup Middle Size League (MSL). It places university teams in autonomous soccer matches: teams design, build, and program wheeled robots that detect the ball, maneuver across the field, communicate wirelessly, and score goals without manual control. KRSBU stresses the integration of mechanics, electronics, artificial intelligence, and team strategy under real-time match dynamics.
