2 - Axis Gyro-Stabilized Platform (Stepper Motor)

The need for a highly accurate pan-tilt platform arose from my struggle to achieve stable, precise movement for applications like capturing cinematic shots or supporting delicate experiments. Existing platforms often lacked the finesse required for smooth, error-free positioning, especially when mounting heavier devices like a DSLR camera. This limitation sparked the idea to create a custom solution that could deliver exceptional accuracy and adaptability.

I designed a pan-tilt system featuring a sturdy horizontal plate that can accommodate various setups. The system utilizes NEMA 17 stepper motors with microstepping, offering finer control over movement. To avoid bulky 3D-printed gears prone to inaccuracies, I opted for a 3:1 pulley system. This setup reduces mechanical errors and ensures compactness. Together, microstepping and the pulley system allow for smooth, precise positioning across two axes.

The platform operates by translating input signals into precise motor movements. The NEMA 17 motors, controlled through microstepping, divide each step into smaller increments, ensuring accuracy. The 3:1 pulley system amplifies this precision by reducing the rotation error, making the platform ideal for delicate applications. In the future, I plan to upgrade the horizontal plate to securely mount a DSLR camera, enabling steady and precise motion for photography and videography. This platform represents a leap forward in creating reliable, versatile, and accurate tools for demanding tasks.
