Voice Controlled Servo Motor Using an Android Application

Abstract

In this paper, a prototype for controlling servo motors using voice commands over an android phone is presented. The prototype includes a DE10-Nano FPGA (Field Programmable Logic Array) board, an RFS card (Terasic wireless communication card), an android phone, a servo motor, and a motor driver board. The DE10-Nano board is a revolutionary FPGA board that is capable of sending precise PWM signals to control the motor. The voice commands were captured using an application we built that can be used with any android phone and is capable of detecting the voice commands and sending them to the FPGA board as ASCII codes. The RFS module secures the wireless communication between the android device and the FPGA board via the HC-05 Bluetooth. The code to run this prototype was written in Verilog and flashed into the FPGA board whereas the android application was built using Android Studio. Show more
