Running the Drive Program on the VEX IQ (2nd gen) Brain

Using VEX IQ (1st generation)? See this article.

The Drive program is a default program built into the VEX IQ Robot Brain so it can be used with Smart Motors, Bumper Switches, and the VEX IQ Controller without programming. The Drive program maps the Controller’s joysticks and buttons to control specific Smart Ports on the Brain.

Step 1: Check that the Smart Ports are properly wired.
