Many of us have had the experience of viewing an artwork in a gallery, in which the eyes appear to follow one around the room. In our high-technology work, this no longer need be achieved with artistic skill. You can just build something that actually moves instead.
Chartreuse is the creation of [alynton], and has a personality all its own. A face was created out of laser cut wood, and assembled layer by layer. It was then given glowing LED eyes, and mounted on a rotating plate. Combined with an Arduino and an ultrasonic sensor, it’s capable of tracking targets moving within its field of view, and rotating to follow them. Chartreuse’s expression changes as well, with from happy to forlorn, depending on the situation.
It’s a great example of the artistic results that can be achieved by layering lasercut materials, as well as how art can be brought to life with simple maker staples like servos and microcontrollers. Motion tracking has plenty of useful applications, too – like aiming heat directly at cold humans. Video after the break.
