A Lego Ev3 catapult made in Italy

Today at Isis Valdarno we have assembled our ball launcher. It has been a great experience to put our hands at work on this great EV3 kit and to get the program ready for our meeting in Poland.


This catapult can launch light plastic balls at various distances according to the program inserted in the brick


We have built the main frame first, and then we have parepared the mechanism and the ball holder. All the assembly has to be lightweight to work well


The main frame is assembled around a motor


Then we added the gear mechanism


In our Mindstorm EV3 Lab we assemble various kits every time. We have a number of teams that work on these projects and that take part in competitions every year.
