My project is like a walking dustbin , it goes around and when it senses someone in the range of 2 or 3 feet it opens its lid and asks for trash.My bot will also separate the trash into metals and non-metals using a magnet.The bot will be controlled by Bluetooth and have a separate app made on MIT app inventor. Usually in big events people have a lot of trash and nowhere to throw it, my robot and i can solve that problem by it going to the person itself and asking for trash. Know u dont need to walk to the dustbin know the dustbin walks to you.
I have completed half of my project , i have connected the IR sensor with the servo motor and Ardiuino, so that when someone comes close my robot opens its lid. I also made a prototype of my project with cardboard so i can get a view of how it will work. i have also started working on my app .
