Id certainly agree with all of the above. Big Nipper is a particular favourite of mine- superb design and build. Panic Attack taken to another level? Unless I skipped passed it theres no mention of Cassius, which although never dominant in combat certainly meets the other three criteria big time, at least in the UK. Two other UK robots that at least deserve a mention are Storm 2 and Kan-Opener. Although Storm is a highly derivative design- effectively a combination of Biohazard and Tornado- and despite some checkbook robotics grumbling, the engineering and design quality of the machine are excellent, the compact size allowing enormously strong armour. Drivetrain power and traction set new standards in the UK. Like Big Nipper, Storm 2 looks more like an American robot. Kan-Opener remains one of the best driven, most dangerous and hard to beat robots on the UK live circuit. The basic design outline has remained largely unchanged, but like TerrorHurtz it has been constantly refined and improved over the years.
