The Gripper is a hands-on 3D printed add-on for your Stackr robot that transforms it into a versatile machine capable of picking up, holding, and moving objects, all controllable from your smartphone. Designed for exploration and creativity, this add-on deepens your understanding of mechanical design, electronic control, and software integration.
What You’ll Learn
🔩 Mechanics – Discover how a gripper mechanism works to open and close its jaws with precision. Learn how mechanical motion translates into controlled grasping using two servo motors — one for arm movement and one for the gripper itself.
⚡ Electronics – Learn how to interface dual servos with your Arduino Nano ESP32 on the Stackr platform. You’ll gain valuable experience in wiring, control signals, and managing multiple actuators.
💻 Software – Strengthen your programming skills by:
Building a Bluetooth Low Energy (BLE) interface for wireless control.
Using the GamePad App to remotely control the arm and gripper.
Writing code to coordinate multiple servo actions for smooth and precise movements.
Why You’ll Love It
The Gripper add-on is a fun and educational project that teaches real-world robotics concepts through interactive play. Whether you’re learning alone or building together with family, it’s the perfect weekend project to develop your skills and bring your Stackr robot to life as a true manipulator.
