Focus projects are projects for students of mechanical engineering in the last year of the bachelor. Sometimes students of electric engineering join them to help with the electronics. In most of the projects the goal is to build a prototype of a product you could sell. To achieve that there are also industrial designers from the ZHdK that help build the prototype.
The main purpose of those projects are the didactic. In some projects there were also patents applied.
