We came up with the idea during our last internship in collaboration with Udoo . A group of IT students from our school had previously created the project for this machine: They developed a voice a voice recognition system that delivers the desired product by pronouncing the name, for example chocolate, coffee, etc.
The voice control was very unreliable and we decided to add a different mode of selection for the final use. We put one big touchscreen display controlled by Udoo board on the front of the machine; also, we decided to control the whole machine at the μcontroller.
