Introduction

Today you will have to come up with your own robot constructions by using the modules we give you. The robots should sort various types of plastics so that scientists can conduct their experiments.

Why do we want to accelerate waste degradation?
Many of the products we are using in our everyday lives are made of plastics or other non-degradable materials. Very often these things are used only once or twice and then thrown away to landfills where it takes them hundreds of years to degrade. A lot of living organisms die as a result of pollution. That is why today we are going to sort waste, resembled by balls of various colors, so that the waste is ready for testing.

An example of slow-degrading everyday products is plastic bags. It takes about 1000 years for a plastic bag to degrade. For comparison, it takes about a month or two for fallen leaves to degrade in autumn.
