Story

Overview

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.

Thompson pods dispenser

This simple diagram explains the operation of the pods distributor.

1. Wafer loading: the pod falls into the Thompson.

2. Servo ON: the servo-motor (piloted by Udoo) rotates 180°

3. Wafer release: the pod falls down the Thompson and, with a ramp, the pod reaches the user.
