Driving is a highly dangerous activity that really only people who are qualified and fit enough for it should do.
Yet we made whole regions dependant on driving. Depending on the country, driving licenses are handed out to kids after a 2h course and we let old, demented and totally unfit people drive as if it was a basic human right.
We wouldn’t let just anyone drive a small forklift at low speeds, because we understand that to be dangerous, but just about anyone can drive a heavy truck or SUV at high speeds.
Yeah, a tattoo printer would have to be at least a 5 axis robot. Technically, that’s not a huge issue, and even pressure sensing or using machine vision to adjust the print aren’t that difficult to do.
But even if it becomes a mass produced device, manufacturing costs for the robot part alone would be at least 3k-5k and then you will need a skilled operator to control that thing.
So you are replacing a minimum wage tattoo artist with an expensive robot and an even more expensive robot operator.
Doesn’t really make sense.
