The prototype we designed isn’t the finished product.

In order to turn the prototype into a standalone classroom kit (“leskist”) it requires quite some more development. A classroom kit is like a chest full of secrets and excitement; children do not know what is inside and are very eager to find out. Schools can order Kosmo and when he arrives it is easy to set up, anyone could do it.

Kosmo the Recyclenaut will be in a class for a week, so five days. When Kosmo arrives the teacher should have to put very little effort into it. Setting it up has to be easy and only exist of opening the chest and it should be ready to go. After turning it on the teacher can select a timeframe when the installation has to be active. For example: during the lessons Kosmo should be idle but during lunch break he can be more active and the volume can also go up.


The technique used for the lids of the bins looks very neat. However, children can handle products very roughly and the materials en techniques used now are not suitable for their possible behaviour. What needs to be done is making it “monkey proof”, i.e. if monkeys cannot break it children cannot either.

The lids should also be incorporated with better (more expensive) sensors so small pieces of trash can also be detected. When placing the sensors the sensing range should not cross the entry so it will not see anything moving in front of it. So they have to be placed quite low, this also necessary to make sure children cannot cheat e.g. by using their hands to activate the sensors.
Ideally, the bins can also detect when the wrong type of trash is thrown in the bin.

The screen has to be as energy safe as possible and also well incorporated in the lid of the chest.


The software, that is the program that runs the installation will require a lot more work.
A very essential part of being in a classroom for one week is saving data. When the day is over and the installation is turned off, the program has to remember how far the children have come so they can continue the next day.

Important is that children will not be punished when they do not produce a lot of waste to give to Kosmo because little waste is actually a good thing. That is why the machines’ feedback has to have a program that adapts to the amount of waste being thrown in the bins. If there is not a lot of waste, the meters should fill quicker than average so it is equally fun for everyone. Also vice versa, when children throw in a lot of waste the meters will fill slower. Each recycle machine has to have its own program in case there are only one or two types of waste that is overly or slightly present.

The prototype has for each type of waste one recycled result. However this can be expanded on to show children what is possible with recycled materials.
Out of paper Kosmo is also able to make drawing paper because he loves to draw, boxes and newspapers (he can take these with him to the toilet). Plastic can also be made into pens to draw with, bottles and even clothing. Organic waste can have much more variety on the planet such as bushes and animals starting to live on the planet. It could also result in fruit trees so Kosmo has something to eat.
Conducting out of the last playtest we can state with certainty that extra products should definitely be added to emphasize the variety of products that can be made.
