Esposito OS is a simple operating system designed for the ESP32 Cheap Yellow Display (CYD). It features dynamic application loading from an SD card and utilizes an event-driven architecture. The system follows a single-tasking, single-app model with a Palm-style lifecycle that allows apps to checkpoint and save their state.
Main points:
- Dynamic app loading via SD card filesystem
- Event-driven architecture using a central queue
- Hardware support for ESP32 CYD (2USB version) and BBQ20 keyboard
- Built on the ESP-IDF framework

We designed and built a 12 degree-of-freedom (3 servos per leg × 4 legs) quadruped robot controlled by a Raspberry Pi Pico W, featuring integrated environmental sensing and a wireless WiFi controller. Starting from a custom CAD body and 3D-printed frame, the robot combines mechanical engineering and embedded electrical engineering to create a platform capable of coordinated four-legged locomotion, heading determination, environmental mapping, and target detection. In order to do so, our system leverages several sensors including an IMU, a solid state LiDAR sensor, and a contact-less infrared sensor.
