Self-Defending Fortress

Recommended Posts

Another crazy idea. Castle MOCs have always been immobile, and so... defenseless. What if a castle was suddenly attacked by some angry Technic creation? It can't jus give up!

See it in action here:

Self-Defending Fortress

It is driven by 3 NXT motors, two for the wheels and one for catapults. And you never know what it will do next... :)

Full set

Enjoy and... Beware!

That's great! Might not be the best on rough terrain, though, so how 'bout making the towers detach and extend out like legs so it can walk over larger obstacles? Maybe for a version 2? :laugh:

The collision-avoidance and auto-firing action is great. Nice work!

Very nice! Love the catapults, how far does it shoot? It can hit targets a meter away, but how far does it come?

It's really a crazy idea, but a cool one. I shared the link with my colegues here at LUG Brasil and everyone enjoyed so much. Congrats!

What a great hybrid of technic and castle! Those cataupluts rock... do you have pictures of the naked chassis?

Haha, crazy!

I viewed your older projects and I like them a lot. Lot of great stuff you got there!

P.S. I recently got from my looong Lego Dark Age so got lot of to catch up. Is Technic now got collision-avoidance system? Or you used some self made system?

Nice! I really like the catapult loading mechanism. I know nothing of technic or motors, so this really impresses me.

I don't particular care for the actual movement of the castle, but I like seeing the movement of the catapults, so kudos.

Keep up the great work! That'd be fun at a show! (outside of hitting a kid's eye)

It's about a metre usually. Quite well as for a brick construction :)

It's simply an ultrasonic sensor, from the 8527 Mindstorms NXT set if that's helpful :) No system of my own so far.

Thanks a lot for the comments! And in case you were interested, I've added 3 photos of the mechanisms inside to the Flickr set (ones at the bottom):
