I've been doing some testing with the ultrasonic sensors that I might implement into the ASV or future projects. I made a ragtag looking movement tracking robot. It can sense when and where an object is in front of it and follow the object around. It was made up of spare parts I found lying around the workshop. It consists of two ultrasonic sensors and a spare servo motor. The mount is an old 3D print for the wire bender project that didn't fit.
