So off the shelf discs are banned? That seems a little odd (though sensible too) It has to be one of the few occasions where we roboteers would be using something for its intended purpose! I have just bought 2 blades to go on our wooden machine...
Its not a massive issue as we can simply take the blades off at the RR events and the like and run the machines as rambots but surely Robochallenge would be ok with running off the shelf discs. Do we know the exact reasons?
