In this high-tech STEAM project, students engineer a small robotic arm from scratch, combining 3D printing, electronics, and coding to bring a mechanical helper to life. The project begins with students printing pre-modeled robotic arm components using ProjoTech’s special kit (ArmX), including base, joints, and gripper parts. They assemble the components precisely, attaching motors at each joint to allow for smooth, realistic movement.

Students use jumper cables, power modules, and signal pins to integrate a microcontroller and wire the system. They dive into coding to develop movement sequences, calibrate servos, and control the arm’s range of motion. In the final phase, they implement slave-bot control—connecting input devices (like potentiometers) to manually guide and map the movement of the robotic arm in real-time.

This project blends mechanical assembly, electronics, embedded systems, and robotics programming while introducing students to real-world automation techniques in manufacturing, surgery, and space robotics.
