I have two answers:
1- Yes we will probably set up several scientific Poppy workshops the next year.
2- There is no reason this kind of event should be organized by us. As the cité des sciences project, it can be definitely done by Fablabs, hackerspace or any other associations or institutions which could explore other applications with Poppy.
So @aurelien, if you would like to participate to this kind of event, you could contact the closer Fablabs/Hackerspace and try to convince them to organize a “Poppy camp”
