Steel is more ductile than the fiberglass or kevlar that you will find in a lot of timing belts. Which is "more durable" or "stronger" depends on material properties which is an entire science in and of itself.
Just know that chain will stretch with use, and is harder to replace for someone who has no experience if you are just handing the drive off to a separate group. More information about the specific use of the bot would be helpful if you want the best possible answers.
As for wheels, Colsons all the way. They wear slower than Hi-Grips and have a higher friction coefficient with carpet. If the robot isn't competing you may want even higher durometer wheels than Colsons though, so that they wear even slower. Colsons can last 100+ matches on carpet, but if its on pavement at a demo, you will eat through an 0.125" drop before you know it.
The reason I care about it is that I don't want minorities (whether that's females or other racial minorities) to see the STEM world as only inclusive of majorities or men. - Monochron [more]
