Rocket Launcher Add-On — Aim, Fire, and Learn
Turn your Stackr into a dramatic, hands-on launcher with the Rocket Launcher add-on. This 3D printed modular attachment features a four-barrel launcher and a servo-actuated trigger mechanism that fires small projectiles either one-by-one or in a fast sequence. It’s built for experimentation and education, a great way to explore mechanics, control systems, and safe engineering practices.
What You’ll Learn
🔩 Mechanics – Study the launcher’s multi-barrel design and the trigger linkage that lets a single servo release each barrel in sequence. Learn about timing, kinematic linkages, and how small mechanical changes affect firing behaviour.
⚡ Electronics – Interface the servo trigger with your Arduino Nano ESP32 on the Stackr. Learn servo wiring, power considerations for safer, repeatable operation.
💻 Software – Build the control logic for reliable launches:
- Implement arming/disarming and firing modes (single shot vs. rapid fire).
- Create a BLE interface and integrate with the GamePad App to remotely aim and trigger launches.
- Program timing, debounce, and safety interlocks to ensure predictable behavior during tests.
Why You’ll Love It
The Rocket Launcher is an exciting project that ties together physics, mechanics, and coding in a way that’s immediately rewarding. It’s perfect for short workshops, classroom demos, or a weekend build.
Safety First
This add-on is intended for educational, low-energy demonstrations only. Follow these rules to keep play safe and fun:
- Use small, low-mass projectiles only.
-
Never aim at people, animals, or fragile objects.
- Operate under adult supervision and wear eye protection during testing.
- Keep launch energies low and test in a controlled area.
There is more
This Add-On is compatible with the Alvik Robot.
