“Existential Robot” is a prototype for an independent robot. His main activities are moving around and expressing his feelings about life in general.
The Robot will move around in a random pattern - on wheels, powered by two DC motors, one for each side. The motors will be integrated with ATmega324 using a L298N motor driver. The Robot will be careful not to hit something; so, two infrared sensors will send information about near obstacles.
For voice, .ad4 audio files will be played through a speaker from a SD card connected to WTV020-SD audio module.

Electrical Scheme
I used Timer0 and Timer1 for PWM. Implemented an algorithm for random movements using information from infrared sensors.
The design could be better.
An overall awesome experience, I got to see what IoT means.
