They throw, they fire, they shoot. This is a category of robots that make an object fly through space and of course through time (because of the special theory of relativity, of course). These are Shooting robots. Try them. How far could you shoot a ball for example?
The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands.
In this video tutorial we experiment with different ways of solving the sports mission for throwing the ball. We show seven different LEGO MIndstorms EV3 and NXT robot constructions and attachements. Most of the techniques could be applied for any mission involving throwing a ball or an object.
