Just what every trebuchet needs, an ultrasonic range finder! It actually works pretty well. Nice job, makers!

This trebuchet ultrasonically determines the distance of the target. This trebuchet was designed, built, and tested by Kettering University Students for Professor Kaiser’s Senior Design Course.

I’d love to see this with a servo in the base to swivel it toward a target…
