12). Team USA took Silver with Original Sin and Bronze
with Last Rites (Figure 13). The best performance by a new
robot was fourth place for the USA’s Polar Vortex by
Michael Mauldin. In what may be a watershed moment for
the Heavyweight division, this is the first time the champion
used brushless motors to power its weapon.
Touro Maximus uses two Scorpion motors to drive a
single spinning drum with four rubber belts.
Perhaps the most exciting new robots were HyperBite
and Doomba — both horizontal spinners with a single
gearbox and multiple brushless weapon motors. Teething
problems prevented these two rookie bots from advancing
to the medal rounds this year, but being able to combine
three or even eight smaller motors to power a single
weapon may allow for even harder hitting Heavyweights in
the future. SV
