Did this jello submerged grape skewering machine have a purpose, or was it just to show the precise nature with which you could code a robot to use pressure?
The purpose was to skewer a grape. It was a competition. We were graded on speed and accuracy.
Yeah, but do you know how to take a screenshot using a Mac like I do?
That is pretty awesome though, still sounds like you should start developing medical equipment for some side money.
I have no idea how to take a screenshot on a Mac. I haven't used one since my G4 cube in middle school.
