If you use sprockets with an even tooth count and space them an even multiple of the chain pitch apart in a single drive/driven configuration you would be able to keep it really simple.
If the chain stretches enough to need tensioning throw it out.
It's really not worth losing the chance to go to Atlana for a couple of bucks worth of streched chain.
You also don't need the extra hardware needed for tensioning to complicate things as well.

Unfortunately, we built a 2wd robot for an earlier competition and the chains stretched enough during the game that they tended to jump off. Using #25 chain just seems to require it if you have any distance to cover with it. Anyone else concure or disagree? all inputs are welcome. thx.
