FLL is an international LEGO Robotics competition, teams all across the globe have to solve a real world problems, build and program robots to do tasks on a field mat, and most importantly work together as a team.
Planet Robotics noticed that sometimes trash cans are overflowing with trash (think weekend, 4th of July, Labor Day, summer). Everyone wants to make the right choices but they don’t know where to dispose of trash when the trash can is full. So the team is working on designing a smart trash can that detect when it is 80% full and pings an alerts to a Waste Management professional about its status and location on a smart phone app, that way they can address it with priority. Its easier to keep public spaces clean if the litter is in the can. The design is based on Ultrasonic sensor, micro controller based Arduino, WiFi module sending alerts to app with GPS location and status. A typical message will read ‘trash can at location 14 is almost full (red), please refresh cans’.
