Deathcap: 3lb Combat Robot

The most adorable 3lb vertical drum spinner.

Deathcap (formerly named Dominant Mode) was my first personal combat robot ever. The design was based off some scrap parts from Jamison Go’s Dominant Mode, and is possibly one of the densest beetleweights out there! Deathcap’s drive has intermediate wheel supports isolated from the outer frame rails to minimize damage to the drive train when taking hits. The armor is hardened and tempered 0.035″ sloped spring steel to deflect horizontal spinners. Don’t be deceived by Deathcap’s small and cute exterior, because those hardened tool steel teeth can do a ton of damage and throw you into the air!
