Concussion

Concussion's construction is weapon focused; the whole design is to keep the 6000 revolutions per minute drum (which has been machined from a single piece of hard steel) pointing at the enemy. This combined with a laser cut precision welded frame, hardened steel side armour and an invertible drive system form a comprehensive design that is effective against a variety of opponents.

Additional information:
The whole team are huge fans of the show – Tim and Carl were VIPs at series one filming and decided to get a team together and build a robot to compete. By analysing the current designs and other robots weaknesses the general idea of a drum spinner came about – to bring something relatively new to the UK. One major downfall of many robots was their weak drive system – inevitably allowing them to be pushed into the arena hazards, so they decided to prototype the drive system with a wooden model – of which they managed to pull a 1.8 tonne car at over 5 miles an hour.
