In this second video lesson on catapults we improve the stability of the base of the robot. An important feature of the new base is that it is not bending. Use the same principle in all of your constructions to achieve better, stronger robots.
We just had some enormous amount of fun with building and using a catapult/trebuchet. Yes they are quite different, but the result achieved in the lesson is something in the middle. Learn how to fire elements using the LEGO Mindstorms EV3 or NXT robotics set. Challange yourself, your team or your students to build it and fire elements as far and as accurate as possible.
