ROBOT TARGETS EYEBALLS, FIRES LASERS. OSHA’S GONNA love this one

If you even think about hacking with lasers, you’re going to hear about eye safety. “Be careful” they’ll say. “Don’t look into laser with remaining eye” is a joke you’ll not be able to avoid. You’ll hear “Where are your goggles”, and about 1000 other warnings. Don’t get us wrong, laser/eye safety is important. However, the constant warnings can get a bit old — especially when you’re working with a “low power” class 3a laser — you know, the kind with a alerting label that says “AVOID direct EYE EXPOSURE” in big black letters on a yellow background.

[Michael Reeves] got fed up, and went a bit nuts. He built a robot specifically to shine a laser into human eyes. No, not a medical robot. This ‘bot lives in a pizza box, is built from servos, duct tape, and [Michael’s] tears. It just shoots lasers at people’s eyes. Needless to say, please, don’t try this at home, or at all.

Designing such a diabolical beast was actually rather simple. The software is written in C#. Frames are captured from an old Logitech webcam, then passed into Emgu CV, which is a .NET wrapper for OpenCV. [Michael] runs a basic face detection algorithm, and uses the results to goal a laser. The laser is mounted on two R/C style servos. An Arduino forms the glue between the servos and the PC.

[Michael] has a terrific deadpan delivery and it all makes for a terrific video. think of him of a younger [Medhi] over at Electroboom.  But we can’t condone this behavior. appropriately labeled and characterized red laser guidelines have never been shown to cause eye damage. Yet if the laser is out-of-spec or reflects of something that additionally focuses the beam it is certainly capable of damaging eyesight.

We want [Michael’s] eyesight to remain intact so he can make more videos — he’s entertaining, even if ignoring safety warnings isn’t.
