Worlds Fastest Roomba Gets Upgrades

A little while ago I modified an iRobot Roomba 630 into a high speed radio controlled vehicle. It was fun and fast, but there were quite a few design flaws that made it difficult to drive. In this video, I'm fixing up some of those issues by 3D printing stronger parts, adding aero and fitting some different electronics. Then I hit the track to see how it performs.
