In my first update, I've mentionned that 3 forces were needed. Obviously, I can't really use 3 actuators (1 motor and 2 linear actuators or 3 motors...), that would be overkill for such a device. Ideally, a single motor would have to be able to deliver those 3 forces but time is running so I'll work a simpler solution for now that we'll be using using 2 actuators (2 motors including the one from the kit). If it works and if I still have time, I'll see if that can be improved.
I have started to play with different ideas like 'rails/guides' but I'm not yet sure this would be the best approach. We'll see...
And again, LEGO Technics combined with 3D prints are great to physically mockup simple mechnical idea!
