Getting Started with the Cortex


Listed below are a combination of PDFs and videos which will help you get started using the VEX CORTEX. They will take you through building a robot, getting the CORTEX up and running, and writing code.

 

Build a robot

Dont have a robot built yet? Here is a simple design, complete with step-by-step building instructions.

  1. RECBOT Building Instructions [PDF]

Preparing the Cortex System

ROBOTC requires special firmware to communicate with the Cortex and Joystick controllers.

  1. Download Cortex Master Firmware [Video] - Update the Master Firmware on your Cortex using ROBOTC
  2. Download VEXnet Joystick Master Firmware Part 1 [Video] - Download the latest firmware to your Joystick
  3. Download VEXnet Joystick Master Firmware Part 2 [Video] - Part 2 of downloading firmware on your VEXnet Joystick
  4. Pairing the VEXnet Joystick with the Cortex [PDF] - Pair a VEX Cortex microcontroller to a VEXnet Remote Control
  5. Download ROBOTC Firmware to Cortex [Video]

Download a ROBOTC Sample Program

Sample programs provide already-working examples of how to program in the ROBOTC language, and can be downloaded over VEXnet or USB.

 

Option 1: Downloading over VEXnet

  1. Download a Sample Program Part 1 [Video]
  2. Download a Sample Program Part 2 [Video]

Option 2: Downloading over USB

  1. Download a Sample Program [PDF]

Modifying Code Examples

Make changes to a sample program to see how your modifications affect the robots behavior.

  1. Moving Forward - Program Dissection [Video]
  2. Moving Forward - Reversing Motor Polarity [Video]
  3. Moving Forward - Renaming Motors [Video]
