What is the VEX Robotics Competition?
The VEX Robotics Design System was developed and engineered with co-curricular and extracurricular robotics competitions specifically in mind. VEX equipment owners have a rapidly expanding selection of opportunities to experience the fun, motivation and excitement of competition. Some robotics competitions feature the VEX System exclusively while others have made select VEX components legal for participation. While the goals and resource requirements of these programs vary, they each leverage the affordability, reliability, flexibility and safety of the VEX System and components. Following are three programs developed exclusively for VEX equipment.

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.
Preparing the Cortex System
ROBOTC requires special firmware to communicate with the Cortex and Joystick controllers.
- Download Cortex Master Firmware [Video] - Update the Master Firmware on your Cortex using ROBOTC
- Download VEXnet Joystick Master Firmware Part 1 [Video] - Download the latest firmware to your Joystick
- Download VEXnet Joystick Master Firmware Part 2 [Video] - Part 2 of downloading firmware on your VEXnet Joystick
- Pairing the VEXnet Joystick with the Cortex [PDF] - Pair a VEX Cortex microcontroller to a VEXnet Remote Control
- 4a. VEXnet Joystick Calibration [PDF] - Procedures for calibrating the joysticks
- Download ROBOTC Firmware to Cortex [Video]
- 5a. Driver Installation [PDF] - How to install the USB-to-Serial-Cable Driver
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
Option 2: Downloading over USB
Modifying Code Examples
Make changes to a sample program to see how your modifications affect the robots behavior.

Curriculum Resources
ROBOTC for Cortex
This set of lessons is currently under development and should be complete by the end of October. This will get you started.
Carnegie Mellon VEX Curriculum
The VEX curriculum is a one stop shop for students that want to learn how to get the most out of their VEX hardware and software.
To learn how radio signals are sent, how much current that your robot will draw, how much weight will a motor lift, or the relationship between gears, speed, and torque go here:
Lessons > Electronics, Programming, and Hardware
To learn the logic behind how to program your robot, how your VEX sensors work, and how to program in ROBOTC go here:
Programming: Make your robot intelligent
To learn how to use a multi-meter, how to solder, how to crimp, how to fasten parts to your robot, or how to tap a hole go here:
Teaching ROBOTC for IFI VEX Robots
This set of lessons assumes that you are a new programmer that is just beginning to use ROBOTC and VEX hardware. Move step-by-step through these lessons learning about fundamental programming logic, how to control your robot’s movement using code, how to program your robots radio and how sensors work. Invest a little bit of time with these units and you will be
programming your robot to do all kinds of cool things.
