There are six robots on the field.

To maximize the distance measuring precision of the camera it needs to be mounted low on the robot.

Its very likely that your bots view of the target light will be blocked from time to time.

With the gyros and accelerometers you can design an inertial guidance system that cannot be blocked or inhibited by any other objects on the field.

The more senses (sensors) you robot uses the better it will be able to perform over a wide range of variables, most of which are out of your control. Once auton starts you dont know what the other 5 robots on the field are going to do.
