Well sounds like a butter fly drive set up would be perfect for 3.5" wheels. The extra .25" clearance over the pulley OD will help keep the pulley and belt safe and since the wheels are capture in a module, you could rise the frame a bit to give it a good gap over the the carpet.
You still don't want the belt the scrape the ground even if its not common. the 3" wheel has no margin for that. Do you need a smaller wheel for more gear reduction?
The driver must have a relationship with the robot, the driver should talk to the robot, speak soft encouraging words to it. Pet names are also a good idea. If the driver does not love the robot, how can the driver learn to trust the robot. - Gboehm [more]
