Each one of the three projects were developed with the collaboration of two different groups: one would be in charge of the physical design of the object and content and the other of the mechanics (including programming)
At the end of the workshop all teams manage to produce the mechanics and they were working manually. The students wrote also some code for Arduino, but they did not have time to fully integrate the different parts, so we end-up with almost finished prototypes.
Teachers agreed to complete them if they had free time.
We really hope all kids participating enjoyed the activity and learnt something useful!!!!
