Which of the robot warriors will take home the trophy, and which will rust in pieces?
So far we know five finalists: Behemoth, the oldest robot in the competition; Carbide, the current champion; Rapid, the most expensive machine; Nuts 2, who everyone thought was a joke but has managed to prove themselves; and Magnetar, designed by a boy genius who hates being called a boy genius.
Before they face each other there is also the Ten Robot Rumble, a last-robot-standing fight to the death. Taking part in this are Apollo, Big Nipper, Concussion, Eruption, Expulsion, Iron Awe 6, Sabretooth, Terror-Hurtz, Thor and Track-Tion to see who will face the other finalists.
Robot Wars is on BBC Two at 20.00.
