Extreme Robots is in Colchester in September, close enough to me (within 100 miles), that I can justify making it the teams first event.
So because PC Plod won't be ready for heavyweight competition, The Scrappers are making an invertable wooden wedge, driven by Argos drills to enter into the featherweight division. The goal being to keep it as cheap as possible, whilst still being effective.
Due to a lack of experience and time, we've decided to go with two chain flails attached to the back of the bot as our main weapon. We're also considering adding some spikes facing up the wedge, allowing us to hold others on top of the robot (should they drive up it) and drive them around.

Some questions before the build officially begins:
1) What is an average size guide for featherweight bots?
2) Which type of sheet metal and what thickness would you recommend we cover the wood with for armour?
3) Are the spikes on the wedge worth it? Would they help control other bots, or just get in the way when running upside down?
