Cake cutting is so exhausting, right? If only there were some sort of robot that could deal with the hassle of figuring out how to get nice matching slices instead of some clumsy (and possibly biased) human just eyeballing it.

Now, if only there were a robot that would make us a giant cookie for that Lego machine to cut up...Oh, wait, for $285,000, you can get one of those, too! [via Make]
