In the unlikely event of a chain breakage, how long would it take to replace the chain?
Theoretically it should be impossible to generate enough traction at the wheel to overcome the tensile strength of the chain.

That said, it didn't look plausible to us to replace a chain in the heat of battle.

So, to give ourselves comfort we built a complete chassis in the pre-season to test the setup. This included stress testing the chains by continuously going between max forward and reverse torque. We survived this testing without incident.

Both the practice bot and comp bot went the whole season without a blown chain. Once I recall we had a chain jump the sprocket and jam...this was determined to be cause by a rivet body that had made its way under the chain and sprocket....it was resolved without removing any parts.
