Cake Cutting Robot made from LEGOs

Robot Cake Cutter
Have you ever gone to slice a cake and ended up creating funky, uneven slices that weren’t as attractive as you’d hoped? Cutting a cake badly has happened to everyone at one time or another. Fortunately, it doesn’t take anything away from the taste of a cake, but using a gadget like the Mindstorm Cake Cutter would ensure that you get perfectly shaped cake slices, too. The mechanized cake cutter was built from Legos and uses a Mindstorm NXT processor, two touch sensors and three motors to do its work. The user simply enters the number of slices that they want to get from the cake, from 1 to infinity (although you would want to choose a number that would provide satisfying slices, of course), and the machine divides that cake into perfectly even slices. The “blade” is actually the lid of a can, which works like a pizza cutter to roll through the cake.

If you were to build on yourself, you might need to have a larger “knife” to cut through deeper layer cakes and you would definitely want to give the blade a spray with vegetable oil to help it slide through sticky frosting and make it easy to clean. A sharper blade (such as one that is actually from a pizza cutter) would let you cut pizzas and other, tougher foods. It would be fun to have some Jetsons-esque automation in the kitchen with a few robots to help out. Cake cutting might not seem like the most useful thing for a robot to do, but mixing and baking the cake is the fun part, so I would much rather have the robot help me out by cutting any number of perfect slices in my cake. That said, I don’t think I’m handy enough to build myself a cake cutting robot just yet, so I’ll stick to the old fashioned method of using knives for now!

  1. Even with the shallow cutter, the robot could at least score the cake (or pizza) to give a guideline on how to cut the slices evenly.

    Very cool!

  2. Wow, I wonder, what can’t Legos do. This machine is amazing, but I would need a bigger kitchen to put it to great use.

  3. I am not very good at cutting even slices of cake. This machine is amazing! Cake cutting is NOT a piece of cake. :)

  4. It’s just a similar copy of my original creation which I made in 2009. It’s just as windle to publish this video. You can see the original here:
