Waiteri
The Waiteri is a new concept in robot design.  Rather than having lethal primary
weapons such as explosives or energy beams, this robot uses a combination of
magnetic attraction and wind repulsion to put its foes off balance.  Because force
shield generators are specifically tuned to a robot's standing position, a successful
attack by the Waiteri will leave enemies vulnerable after disrupting their energy shield
protection.  The Waiteri's strange weapons are backed by kala explosive cannons.
