A snake robot - that eats rubbish in storm water drains. It has a waterproof camera on the head. If it "sees" a object that is "identified" as rubbish the snake will eat it.
There will be different "species" of robot snake. One to eat glass rubbish. One to eat plastic. One to eat aluminium cans and tin cans. One for general waste compost.
Natural snakes are known for their ability to fit seemingly impossible large food items inside their bodies and crush and decompose these items. A robot snake maybe a solution to waste management of drains.
The robot snakes have a GPS inside and will navigate storm water pipes and return to a base for emptying.
