Arduino Uno Code for E- Dustbin

E - Dustibin is the future of world, So every developing country is now finding the ways of collecting the garbage according to their category, like plastic garbage , metallic garbage, or biodegardable and not degradable items saparately.
So to have this thing in mind we have develop a science project of moving and auto open close and E- dustbin. Which will move at predefine path and collect the garbage and also automatically opens when user comes in near to that.
