Lucas discovered that slippery stairs at home posed a high risk but lacked timely warnings. He designed and developed an anti-slip system based on pressure sensors and optical detection that could monitor ground humidity changes in real-time and provide dual reminders to pedestrians through voice and LED lighting. To reduce false alarms, he conducted long-term testing under various materials and angles, continuously optimizing the algorithm's filtering logic. In multi-scenario validation, the system provided 85% advance warnings of slip risks and was introduced to several public stair safety renovations, offering innovative protection for campuses and communities.
