NEW BLOOD 1
 * Terror Turtle, Niterider, Maximus, Night Raider and RT81 all fall reasonably quickly, mostly by just not working.
 * Under the pressure, I don't trust Mr Nasty, Hell's Teeth or Chip to last.
 * That leaves just Roobarb, Mute, Thor and Edge Hog. Given the circumstances, Edge Hog was the only one who didn't last, so I have to vote it out.

NEW BLOOD 2
 * Doctor Fist never works. End of discussion.
 * Chopper, Mad Dog and Bash Gordon will probably also go down in a few hits.
 * Of the remaining robots, I only see Storm 2, Cedric Slammer, Piranha and Pressure lasting without any issues. And since Piranha is probably the weaklink, I'll vote it goes out last.

So, in conclusion, Roobarb, Mute, Thor, Storm 2, Cedric Slammer and Pressure go through.
