Some time back, my son was playing with paper planes. Then I got the idea to make an automatic launcher for it. Here’s the result:
It’s mainly made with the Lego Mindstorms EV3 kit, along with a couple of other Lego bricks here and there.
The programming happens with a graphical programming language. You basically just drag the different blocks in place.
Interested in more Lego Mindstorms projects? Check the Lego Fair or the anti-theft measures I took.
