Voice Controlled 4 DOF Robotic Arm
CompleteWhy
Why
Voice interfaces lower the barrier to operating robotic hardware without a direct controller. This project investigates how natural language commands can map to precise servo movements in a 4 DOF arm.
How
How
Modeled the arm in Onshape and printed the links in ABS. Wrote servo control firmware in C++ on an Arduino, then built a Python speech-recognition layer that parses spoken commands and sends serial instructions to the microcontroller.
Results
Results
Achieved reliable control through voice alone with sub-second command, and developed a "J.A.R.V.I.S." style user interface that can execute multiple commands. The project was presented at the University of Redlands Engineering open house.
