A thought about those front forks. When the bot is upside down the weapon will, in effect, be spinning downwards, so if it hits something it will end up trapping whatever it hits between the forks and the weapon will stop. While this probably not going to break the weapon, it may well bend the forks and it will give the weapon motor and belt a massive shock. Given my new version of Conker is very similar I have been thinking about this a lot, and I believe you only need forks on one side so you can use the weapon to self right on the arena wall/opponent when the wrong way up.
