If the robot were running for months straight, then yes, steel would probably be in order.
However, you're running your robot for two minutes at a time, perhaps 50 times tops over the course of a competition season (unless you go to a metric ton of off-seasons). In that sort of situation, I have empirical evidence that suggests that aluminum sprockets, such as those sold by IFI, AndyMark, and perhaps others, wear acceptably. If you're really worried about it, bring a couple of spares (though you should do that as it is)...but you should be fine in most situations with the aluminum sprockets properly installed.
