I was wondering if anyone knew what sensors the teams used, and where they can be purchased. Hopefully I am not going in over my head, and if you have any advice, I'd love to hear it!

Check out Robo-Magellan. The robots are less than 50 pounds and must fit in a 4 foot cube. The straight line distance from start to finish is less than 300 feet, although it is not possible to follow a straight line due to obstacles. This sounds like what you're interested in.
As I recall the original rules came from the
Seattle Robotics Society . They ran a competition last weekend at
Robothon in Seattle. The
Portland Area Robotics Society also ran a competition at
PDXBOT back in April. The PDXBOT site has a number of pictures. Several of the entrants look to be based on RC trucks. Several of the PARTS members participate in Robo-Magellan and there has been some Robo-Magellan traffic on the
PARTS mailing list recently. I'm sure the folks there would be happy to offer advice.
