The sword, motors :

The goal of our game is to release the sword locked by a structure. For this structure to activate, all three LEDs associated with each stage must remain lit simultaneously. We encountered an issue that prevents it from working, which we will address shortly after showing you the evolution of the sword.

Try to find how to take off the sword : 

For the selection of our final sword, we based it on a cardboard prototype that we gradually refined over time to achieve a size suitable for our box and the notch to fit it. In the end, we made our sword from a sturdier and neutral (white) cardboard for aesthetic reasons.  The final thickness at the widest part of the blade is 0.7cm, and its length is 16cm.

As we built the system during the long weekend before the holidays we also tried to see if it works on the box. For this system we thought about 2 disks that would have ¼ removed so the guard of the sword could go inside of it. Thanks to the 2-servo motor that we have we can make the 2 disks move so they will unlock the sword and move it upward a little. We had an issue with the motors because they should be moving together but we didn’t managed to do it. We wanted to hide this system in a fake rock but we didn’t have time to do it.
