Mastering the VEX IQ (2nd gen) Competition Kit


The VEX IQ 2nd gen Competition Kit is a comprehensive collection of parts designed to facilitate advanced robotic design and problem-solving. The competition add-on provides additional components tailored for competitive environments.


The base VEX IQ 2nd gen Education Kit is comprehensive, but the competition add-on is designed for those seeking to engage in competitions. It offers enhancements for mechanical efficiency, sophisticated designs, and competitive advantages.

Categories of Parts and Their Applications

This section provides details on the exclusive components in the VEX IQ 2nd gen Competition Kit, which are absent in the Education Kit. For a complete list of the Competition Kit components, view this poster from the VEX Library. Note the Education Kit is the first page contents, and the second page is the Competition Add-On. Together, these two pages make up an entire Competition Kit.


Linear Motion

  • Description: Allows for smooth movement along a single axis. Crucial for tasks like lifting or pushing objects with precision.
  • Example: An extendable robot arm that can reach and retrieve objects from different heights.



  • Description: Converts rotational motion into linear motion. Useful for creating unique movement profiles.
  • Example: A robot mechanism that can emulate a rod extending or retracting due to the unique shape of the Cam, coupled with the Cam Follower.


Linear Motion

  • Description: Allows for smooth movement along a single axis. Crucial for tasks like lifting or pushing objects with precision.
  • Example: An extendable robot arm that can reach and retrieve objects from different heights.


Ratchet Pawl and Spool

  • Description: The ratchet and pawl mechanism permits movement in one direction and restricts it in the opposite. With a spool, it securely winds materials like string without unintentional unwinding.
  • Example: In a robot, this system can lift objects, ensuring they don't drop when lifting force ceases.


Hybrid Gears, Rack Gears, and Worm Gears

  • Description: Hybrid gears transmit power between non-parallel shafts, while rack gears change rotation to linear motion, and worm gears boost torque.
  • Example: A climbing robot might use hybrid gears for 90-degree wheel power. Rack gears could aid a lift system due to the linear motion, and worm gears give cranes high torque.


Rubber Belts

  • Description: Rubber belts can function as intake tools or form tank treads for better robot traction.
  • Example: One robot might use belts to collect objects, while another employs them as treads for rough terrain navigation.


Shock Absorbers

  • Description: Shock absorbers dissipate energy to protect a robot's structure from rough terrains or impacts.
  • Example: Robots jumping from heights might use these in their legs or base to lessen impact and avoid damage.


Flywheel Weight

  • Description: Flywheels store and release rotational energy, granting robots quick bursts of speed or power. Plus, these weights aren't just for specific tasks – use them as versatile counterweights wherever you see fit.
  • Example: Robots aiming to shoot objects might use a flywheel to rapidly propel items when the energy is released.


Additional Construction Pieces

  • Description: The Competition Kit offers diverse construction parts for flexible and detailed robot designs.
  • Example: Robots aiming for a distinct look or function might utilize these special pieces for aesthetics or particular structural needs.

This list presents the components exclusive to the Competition Add-On Kit. The kit also includes several foundational parts from the Education Kit, such as motors, connectors, wires, and wheels, ensuring a comprehensive building experience.

Competition Kit Benefits


The Competition Kit enhances robotic capabilities with a wider range of parts than the Education Kit.

Additionally, users can access this year's Full Volume STEM Lab at If you're new to the VEX IQ Robotics Competition, this platform introduces the Herobot, guides you through its coding, and prepares you for competition with the augmented kit.


Competition Kit Parts Poster: This guide provides a detailed overview of each component in the kit, aiding in quick part identification. It also outlines component placement, with the first page detailing the Education Kit and the second showcasing the Competition Add-On components.

Incorporating the competition add-on offers more than just additional parts; it broadens the scope of design possibilities. As robotics and STEM disciplines continue to advance, possessing the right tools becomes essential. The VEX Robotics Competition Kit, enhanced with the competition add-on, equips users for leading-edge innovation.
