Project Liftoff - September 2021 (rev 5.0), pictured before the September 2021 event. The bot went on to go undefeated, winning the 3lb division with 4 KOs and 3 judges decisions.

Project Liftoff is a 3lb MeltyBrain (a robot that moves using translational drift) as its entire body spins at 2500 to 5000 RPM.

As of September 2021, Project Liftoff is in it's fifth major design generation.

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).

Since then, Liftoff has used several laser or waterjet-cut AR500 steel rings. These rings have been sandwiched or otherwise mounted to CNC'd UHMW or HDPE bodies that contain the primary electronics and battery. This has proven to be a durable, and adaptable construction method.
