PyDuino Bot

A set of programs used in an Arduino(micro-controller / µC)-based robot resembling a rover! It can detect human faces using Computer Vision and is controlled by a game developed using the Pygame(a python library) through WiFi.

Components

The following components are required in order to make the robot:

1) Arduino Uno (µC)
2) ESP-32 CAM Module
3) OV2680 Camera Module
4) L298N motor Driver
5) Jumper Wires
6) 2 DC Motors(Geared)
7) 4 Wheels
8) 9V battery
9) 9V battery connector
10) Breadboard
11) Arduino programmable cable

Uploading the Code

- Upload the 'ESP32_MAIN.ino' file available in the ESP32 folder to the ESP-32 CAM trough UART connection
(Upload using the Arduino IDE in windows or the Arduino Droid app in android)

Curcuit

- Connect the wheels to the motors
- Connect the OV2680 Camera Module to the ESP-32 CAM

Usage

- Change your WiFi's/Hotspot's name to 'username' and password to 'password'
- Turn on your WiFi/Hotspot
- Connect the Arduino Uno to your device using the Arduino cable
- Open the monitor of the Arduino IDE/Arduino Droid app
- Change the Baud rate to 115200
- Press the reset button of the ESP-32 CAM module
- An IP address will be visible in the monitor of the IDE/App
- Open the IP address(https://IP_address) to access the camera
- To move the robot run the main.py file available in the Python folder and play the game!
