The Trebuchet of the 21st century
posted November 21 2010 7:51.49 by Giorgos Lazaridis

People usually design minigun-like paintball guns mounted on automatic targeting systems or other sci-fi weapons. This guy over here went a step... back! He designed a trebuchet, with an ultrasonic range finding system. The ultrasonic device measures the target range, and a motor moves the arm accordingly, so that the ball hits the target. This trebuchet was designed, built, and tested by Kettering University Students.
