Mindboards

I am currently developing a strong weapon for my robots that is built entirely out of LEGO elements only, and that got me thinking: Are other people doing this? And if so, how are they doing it? If you have done something like this, go ahead and post pictures for people to see. It is clear that custom weapons may be stronger than regular devices such as Zamor sphere launchers, adding extra range to a weapon based robot. The question is, what have you done?

Botmaster,

Click: NXT Programs has made an awsome machine gun that fires technic bricks.

Cool gun! It uses the same ammo I'm using myself. It doesn't look like it would be accurate enough for fully automated precision targeting. Good for fun though!
