Large Format DSLR Gimbal

Multidisciplinary Mechatronic System for Cinematic Drone and Handheld Operation

Project Overview

This project represented my first end-to-end responsibility for the design, sourcing, and project management of a complex mechatronic system. I developed a high-rigidity 3-axis stabilization gimbal designed to carry cinematic DSLR payloads on heavy-lift drone platforms.

Beyond mechanical architecture, my involvement extended into the electrical integration layer, contributing to open-source hardware configurations to optimize motor control and positional feedback for high-vibration environments.

Technical Contributions

  • Mechanical Architecture: Engineered a lightweight yet high-rigidity frame optimized for drone mounting, featuring quick-detach handles for handheld versatility.
  • Precision Sensing: Integrated Hall Effect sensors to provide high-resolution absolute position encoding for each axis, mitigating drift during high-velocity aerial maneuvers.
  • Mechatronic Integration: Customized brushless motor driver chips and driver logic to interface with the SToRM32 open-source platform.
  • Stress Analysis: ensured motor mounts and structural joints could withstand the continuous torque loads of cinematic payloads.
