Summary
A robotic task light designed to track hand motion and respond to gesture-based commands. Initially designed for desktop use, but pivoted to medical use-case to support sterility in exam rooms.
Problem / Goal
We aimed to create a light system that could automatically follow and illuminate a user’s work area. The design evolved into a no-touch solution for clinical settings, where maintaining clean surfaces is important.
Approach
I pitched the idea and led four of my classmates for our capstone design project. I was responsible for coordinating the technical and administrative efforts and contributed to the mechanical design and prototyping of the structure and motion system.
We completed three major iterations:
- 3D printed continuum arm (abandoned for complexity)
- Parallel arm design using water-jetted aluminum
- Switched to 3D printed arms for lighter weight and smoother motion
Outcome
At the final showcase, all core features worked: gesture control, tracking, and motion.
