I just participated at the Maker Faire Rome 2015, where I gave two talks on Saturday and Sunday (see here for the abstract). Both have been exciting experiences as the attendees were very attentive and curious to know the latest developments in the swarm robotics field.
A live demonstration and experiments with people coordinately moving like fish schools or synchronously clapping like fireflies completed the performance. Kids have been particularly excited to play with the robots I brought on stage.
Many thanks to the organisation and to all the people that enthusiastically participated!
