Bring physics, engineering and hands-on fun together with the HEXBUG VEX Catapult Launcher — a robust, kid-friendly buildable mechanism that teaches cause and effect, mechanical advantage, and creative problem solving. Designed for classroom labs, makerspaces, and curious tinkerers at home, this kit uses VEX-compatible beams, gears, and linkages to let builders construct a working catapult that launches soft projectiles safely and repeatably. The step-by-step assembly encourages spatial reasoning and fine motor skills while clear visual instructions explain how changing arm length, counterweight, and gear ratios affects range and accuracy.
Key features
• BUILDABLE MECHANISM: Modular VEX-style parts (beams, axles, pins, gears) for hands-on construction and easy customization.
• TEACHES STEM CONCEPTS: Demonstrates leverage, torque, energy storage, gearing, and projectile motion with simple, visible experiments.
• SAFE PLAY DESIGN: Soft foam projectiles and a low-force launch mechanism make it suitable for supervised play and classroom demonstrations.
• ADAPTABLE & EXPANDABLE: Compatible with other VEX/HEXBUG components so students can add motors, sensors, or create multi-stage launchers and obstacle courses.
• DURABLE CONSTRUCTION: Reinforced parts and secure fasteners withstand repeated builds and classroom use.
• INCLUDES EXPERIMENT IDEAS: Suggested challenges and measurement activities to turn play into structured lessons (range testing, angle optimization, payload balancing).
Who it’s for
Ideal for ages 8+, educators teaching introductory physics or engineering, robotics clubs, and hobbyists who enjoy iterative design. Whether used for guided lessons or freeform tinkering, the Catapult Launcher turns abstract principles into visible, repeatable results — perfect for demonstrating how small adjustments to a mechanism create predictable changes in performance.
Quick tips
• Start with the suggested build before experimenting with arm length or counterweights.
• Use a protractor and tape measure to record launch angles and distances for simple data collection.
• Combine with a small motor and limit switch to explore automated cocking and controlled release.
Safety note
Always supervise younger builders. Do not aim projectiles at people or animals and use only the supplied soft foam ammunition. Remove small parts from play with children under recommended age.
