Desk buddy | Companion robot with wheels | Code & 3D included

In this project I built a tiny desk companion robot using an ESP32, OLED display and two N20 motors.

The robot roams around your desk on its own, but if you ignore it for too long it stops and asks for attention. When you touch the sensor it becomes happy and stays in petting mode.

The face is generated using a simple physics system that makes the eyes move naturally. The robot uses a DRV8833 motor driver to control two N20 motors and wander around randomly.

This is a fun project that combines robotics, embedded programming and simple animation to create a robot with personality.

Hardware Used
* ESP32-C3
* 1.3" OLED display
* DRV8833 motor driver
* N20 gear motors
* Touch sensor

Features
* Random roaming behavior
* Pet detection using touch input
* Attention seeking behavior
* Animated OLED face
* Physics based face movement

This project is a great starting point if you want to build interactive robots with personality.
