Fresa is a internet connected delivery system where you do not have to accept the order personally. It focuses on fresh and local food, fruit and vegetables.

Fresa is a project from the 4th semester with the overall topic Internet of Things, conceived and developed by Hannah Ackermann, Marco Frumento, Sabine Reitmaier and myself.

Fresa solves the problem of providing regional and local food for busy people living in the city. People who don't have time to shop after work but still want to live healthy have a big problem to buy food after work, because many organic markets are not open that long.

Fresa tries to integrate itself into the lives of working people and meet the wishes of its customers.

Our research has shown that many people unfortunately have only little knowledge about the process of supplying regional food, which causes many to think prejudicially. That is why we try to bring transparency into the delivery process and to show which food comes from where.

In addition to the fact that many people still like to buy their food in shops, the online trade of fruits, vegetables and other foods has also increased strongly. Great attention is also paid to the origin and method of cultivation.

Fresa wants people to think more about where their food comes from. Since Fresa is also responsible for the delivery of food, a concept has been developed in this context which makes it possible that the customer no longer has to wait at home for the food orders, but can quite simply carry out his normal daily routine and can simply pick up his order on their way home.

Fresa delivers its food in food-safe plastic crates, which are delivered to such boxes:


These chambers are mainly located in places that are open until 10 pm, such as kiosks or petrol stations. So you can still pick up your delivery late in the evening.

To enable the customer to identify himself, he receives a Fresa Chip, which has an RFID transmitter installed and can use it on the pantries to open the door.



In the background of the system, MQTT messages are sent back and forth to ensure that we know at all times what state each pantry is in. This allows a good overview for possible maintenance and a live map view in which the customer sees which pantry is still available.

The prototype has been designed so that you can run through a complete delivery process and see all updates on the servers. If the project were to be developed, it would be estimated that the project would only take six months to one year to reach market maturity.

To show how our concept roughly works, you can watch a small trailer here:
