Answered: what kinds of modifications are allowed for Worlds?

We’re a first year team that has qualified to go to the Worlds in Dallas. We are wondering what kind of modifications are allowed to the robot that we qualified with?
[LIST]
*]New sensors and programming for autonomous?
*]New mechanisms for working the autoloader?
*]New appendages for flipping the bonus cube?
*]Any other guidelines?
[/LIST]
We’re not looking to make huge changes, but don’t want to do anything that would DQ us.

Thanks,
Gary

You can show up with a brand new robot if you’d like.
We at VEX Robotics know that “Design is an iterative process.” If there are improvements you’d like to make before the big show, I’d go ahead and make them.
