This competition accepts scores from Programming Skills mode in the VEX IQ Challenge Crossover Robot Virtual World. To submit your score, you must log into the Robot Virtual World using your CS2N account and wait for time to elapse in Programming Skills mode. Once time has elapsed in the game, you will be prompted to submit your score and upload your code. Only submissions that include your ROBOTC autonomous code for the virtual robot will be considered valid competition submissions.

VEX IQ Challenge Crossover is played on a 4’x8’ rectangular field. This simulation allows you to program for the Robot Skills Challenge, where one robot takes the field to score as many points as possible under driver control; and the Programming Skills Challenge, where one robot scores as many points as possible autonomously, without any driver inputs.

The object of the game is to attain the highest score by scoring Hexballs in their colored Scoring Zone and Goals, and by Parking and Balancing Robots on the Bridge.


The winner of this competition will recieve an invitation to the VEX Robotics World Championship — April 23-25, 2017 at the Kentucky Expo Center in Louisville, Kentucky!
