Project LiftOff is a 3lbs MeltyBrain (a robot that moves using translations drift as its entire body spins at 1000 to 3000 RPM.
For 2021, Project LiftOff is beginning its third major revision.

Robot Facts
The first appearance was at the March 2019 NHRL event. The very first version used an 8" diameter aluminum pipe cut into two 1/2" thick slices with a notch cut out for the AR500 tooth (with two bolt holes).
