# Getting Started — VEX IQRead these articles in order to go from zero experience to a competition-ready VEX IQ robot.

Welcome to the VEX IQ Foundations program! This page is your reading roadmap. Work through these articles in order — each one builds on what came before. By the end, you will have the background knowledge to build, wire, program, and compete with a VEX IQ robot.

You do not need to read everything before your first session. Aim to finish each section's articles before or during the matching session block.

## Phase 1 — Before You Touch the Hardware

Read these first. They cover safety, the equipment you will use, and the lab rules.

1. **[Resources: Safety Rules](/docs/guides/resources/resources-safetyrules/)** — Lab safety, emergency stop procedures, and the safety agreement you will sign on Day 1.
2. **[Resources: Tool Usage](/docs/guides/resources/resources-toolusage/)** — How to use hand tools safely and correctly.
3. **[Hardware: The Brain](/docs/guides/hardware/hardware-thebrain/)** — The VEX IQ Brain is the computer at the center of your robot. Learn what it does and how it connects to everything else.
4. **[Hardware: Brain User Interface](/docs/guides/hardware/hardware-brainuserinterface/)** — How to use the Brain's touchscreen to monitor sensors, check port connections, and run programs.
5. **[Hardware: Battery Packs](/docs/guides/hardware/hardware-batterypacks/)** — Charging, caring for, and checking the battery that powers your robot.

## Phase 2 — Building Your First Drivetrain (Sessions 1–3)

These articles cover the mechanical and electrical foundations of your robot's drivetrain.

6. **[Fundamentals: Gear Ratios](/docs/guides/fundamentals/fundamentals-gearratios/)** — How gears change speed and torque. You will calculate gear ratios before building your drivetrain.
7. **[Drivebase: Drivetrains](/docs/guides/drivebase/drivebase-drivetrains/)** — The different types of drivetrain configurations and when to use each one.
8. **[Drivebase: Wheels](/docs/guides/drivebase/drivebase-wheels/)** — Traction vs. omni wheels and how wheel choice affects robot performance.
9. **[Drivebase: Best Practices](/docs/guides/drivebase/drivebase-bestpractices/)** — Structural tips for building a drivetrain that holds together under competition stress.
10. **[Fundamentals: Fasteners](/docs/guides/fundamentals/fundamentals-fasteners/)** — Screws, lock nuts, and standoffs — the fasteners that hold your robot together.

## Phase 3 — Programming Basics (Sessions 2–3)

Read these before or alongside Sessions 2 and 3.

11. **[Software: Python Basics for Robotics](/docs/guides/software/software-pythonbasics/)** — Variables, functions, loops, and the VEX IQ motor API. Start here if you have never coded before.
12. **[Hardware: Motor Encoders](/docs/guides/hardware/hardware-motorencoders/)** — How the built-in encoders in VEX IQ motors measure distance and position.

## Phase 4 — Autonomous Motion (Sessions 4–5)

These articles explain how to make your robot drive accurately without a driver.

13. **[Navigation: Odometry](/docs/guides/navigation/navigation-odom/)** — Using encoder counts to estimate how far the robot has traveled.
14. **[Navigation: PID Controllers](/docs/guides/navigation/navigation-pidcontrollers/)** — The feedback algorithm that lets your robot drive to an exact distance or turn to an exact angle. Read this carefully — you will use PID for the rest of the program.
15. **[Hardware: IMUs (Inertial Measurement Units)](/docs/guides/hardware/hardware-imus/)** — The gyro sensor that tells your robot which direction it is facing.

## Phase 5 — Driver Control (Session 5)

16. **[Hardware: VEX Controller](/docs/guides/hardware/hardware-vexcontroller/)** — The handheld controller hardware — inputs, axes, buttons, and wireless connection.
17. **[Software: Driver Control Programming](/docs/guides/software/software-drivercontrol/)** — How to write a driver control loop, implement arcade drive, add deadband filtering, and tune joystick curves.

---

## Phase 6 — Competition Template (Session 6)

18. **[Software: Competition Template](/docs/guides/software/software-competitiontemplate/)** — The three-phase structure (pre-autonomous, autonomous, driver control) that all VEX competition programs must use.
