VEX IQ Basic

🎯 Target Age

Grade 4 - Grade 8 (ages 9–14)

Goal – Learning Outcomes

Help students to understand how different mechanical systems work together and how design affects performance; learn how sensors provide feedback that allows the robot to make smart, autonomous decisions; develop their logical reasoning, problem-solving.

By the end of the program, students should be able to:

✅ Explain how mechanical systems and sensors interact

✅ Write autonomous and driver control code

✅ Apply engineering design to solve problems

✅ Build and program a functioning robot

Foundational VEX IQ Basic Program Concepts (Teaching Target)

Mechanical Engineering & Structures

Students learn how to design and build sturdy, efficient, and functional robots.

Key mechanical concepts:

• Simple machines: levers, gears, pulleys, wheels, and axles

• Gear ratios: speed vs. torque relationships

• Structural design: strength, balance, and stability

• Mechanisms: arms, linkages, lifts, claws, conveyors

• Friction and efficiency: how to reduce drag and energy loss

• Chassis design: drive base, turning, and weight distribution

Electronics & Sensors

Students explore how the robot’s brain, sensors, and motors communicate.

Core components:

• VEX IQ Brain: robot controller (CPU)

• Smart Motors: measure rotation and speed

• Sensors:

Touch LED Sensor: detects touch and displays colors

Gyro Sensor: measures turning angle

Distance Sensor: measures range

Color Sensor: detects color and brightness

Programming & Computational Thinking

Coding is taught through VEXcode IQ Blocks (Scratch-like) or Python.

Key programming knowledge points:

• Sequence: order of commands matters

• Loops (Iteration): repeat actions efficiently

• Conditional logic: if–then–else statements

• Variables: store and use data (like distance or speed)

• Functions: reusable code blocks for cleaner programs

• Events: starting actions based on triggers

• Sensor feedback: use sensor data to control robot behavior

• Debugging: finding and fixing coding errors

Autonomous & Driver Control

VEX IQ includes two main robot operation modes:

• Driver Control: Students use controllers to manually operate robots

• Autonomous Mode: Robots perform tasks automatically through programming

Students learn to:

• Write autonomous routines for accuracy

• Combine manual and autonomous operation (driver assist)

• Plan strategies for VEX IQ Challenge games

Engineering Design Process

Students apply real-world engineering practices:

1. Define the problem (game or challenge goal)

2. Brainstorm and design possible solutions

3. Build and test a prototype

4. Analyze performance and improve

5. Document the process (engineering notebook)
