From the project

ECNG 4504 (AUC, Spring 2026): autonomous maze-learning & solving robot — MCU (Arduino), Python BLE host app, KiCAD/docs, team deliverables. Single monorepo per course charter.

American University in Cairo · School of Sciences and Engineering ECNG 4504 — Embedded Systems for Wireless Communications · Spring 2026

This project is an autonomous line-following robot that learns an unknown maze in a training pass and later executes a shortened turn sequence to reach the goal efficiently. A PC host connects over Bluetooth (BLE with HM-10, or Bluetooth Classic SPP with a ZS-040 / HC-05) to issue commands, stream status, and visualize behavior. On-robot software is a single Arduino sketch (workingcode.ino) built around discrete line following (no PID), left-hand-rule…
