This Guy Spent a Year and a Half Building a Cake-Baking Robot

Ok, so it doesn't bake the cake. But this messy, imperfect robot, made by the YouTuber 52 Skillz, successfully mixes cake batter from scratch. The long, arduous process is detailed in this video.

What's so great about hearing the process behind the robot is his description of the emotions he felt while building it. You can really feel his joy when parts of the robot work, and desperation when they don't. It's legitimately inspiring to watch someone learn a totally new skill and put it to use. Congrats, cake robot dude.
