Handy Andy ASL Robotic Hand

Langara CollegeJan 2026 – Apr 20260 visits in Sep 2026

Robotic hand prototype connecting live English speech recognition to Arduino-controlled ASL hand movements.

Overview

Handy Andy brings speech recognition and mechanical actuation together in a physical language interface. The project combines a pulley-driven hand with software that coordinates movement between signs.

Role and constraints

I led the cross-functional team as project manager and developed the Arduino C++ codebase, hardware interface, and pulley actuation mechanism.

Process

The prototype uses articulated fingers with servo-driven pulley actuation. I implemented smoothing algorithms to make transitions between hand positions more fluid.

Result

Built a robotic hand prototype connecting live English speech recognition with physical ASL hand movements.
