Abstract
Ree-Ro is a little robot that does not like loud noises or sounds. It will "eat" the sound, and attempt to find where the sound is. In this implementation. It works best with sine waves. Ree-Ro incorporates hardware, software, and mechanical parts. Inside Ree-Ro is a sound envelope detector circuit that is connected to the ADC of the DE0-Nano FPGA board. Ree-Ro's mobility is supported by two stepper motors connected to wheels. The focus of this project is to give basic autonomy to a moving robot.
