When we first built this castle, we were just looking for something to do with our rokenbok that was animated and hadn't been done built by us before. We settled on using Josiah's LEGO mindstorm set to power the drawbridge and falling wall. Our drawbridge features 2 sensors; a touch sensor and an ultrasonic sensor. these 2 sensors regulated incoming cars (it only let certain cars in) and enabled us with a security measure.
