Air pollution and excessive noise are among the most overlooked threats in

today’s urban environments, often affecting communities without visible

warning. This project introduces METROPULSE, a mobile robot designed to

detect and respond to these hidden risks to promote safer and healthier

living spaces. By using a light sensor to represent poor air quality and a sound

sensor to identify harmful noise levels, METROPULSE can move, light up, and

sound an alarm to alert people nearby in real time. The system was

developed and tested using simple block-based programming to ensure it

reacts effectively and remains user-friendly. Beyond protecting the

community, METROPULSE also serves as an educational tool to raise public

awareness about invisible environmental dangers. Supporting Sustainable

Development Goal 11, this innovation empowers citizens to take small,

practical steps toward cleaner air, quieter surroundings, and more sustainable

urban living.
