This is a video from France of an industrial robot
severing a man's calf giving a guy a pretty shitty spiral tattoo on his leg. I mean the spiral is fine, but the actual ink job is questionable at best. It looks like it'll last a couple years, tops. Basically the team 3-D scanned the dude's leg so the robot understood the geometry of its surface, then let it get to work. Better not move your leg unless you like bleeding! Honestly, I'm surprised they didn't implement some sort of real-time 3-D scanning so even if you did move your leg, the robot can respond appropriately and not try to tattoo your bone. This doesn't really seem that sophisticated. Me? I'm ultra sophisticated. The smallest fork at fancy restaurants is for picking your teeth.
Keep going for the video, but skip to 0:42 to see a 3-D printer tattoo, and 2:32 for this one.
Thanks to Gavin, who agrees an industrial robot ain't shit if it can't tattoo a pirate ship or naked lady.
