Welcome to the official repository for a Mechatronics Engineering project — a dual-mode robot car that combines manual control via Bluetooth and autonomous line-following using infrared sensors.
Designed and built at October 6 University – Mechatronics Engineering Department
-
🔹 Two operational modes:
- Manual Mode: Real-time control via HC-05 Bluetooth module.
- Line Following Mode: Autonomous navigation using TCRT5000 IR sensors.
-
🔹 Controlled by an Arduino UNO board.
-
🔹 Chassis custom-designed, laser-cut using CNC machine.
-
🔹 Modular and extendable design for future enhancements (e.g., PID, obstacle detection).

A simple and efficient wiring setup to handle sensor input, motor control, and serial communication.
The firmware is written in Arduino C/C++. It handles:
- Bluetooth input reading.
- Sensor state evaluation.
- Conditional motor actuation.
- ✔️ Manual mode performed reliably under controlled conditions.
- ✔️ IR sensors enabled effective line tracking with minor tuning.
- ❗ Occasional signal noise was mitigated by delays and threshold calibration.
⚠️ PID control was researched but not fully implemented due to time constraints.
Planning was one of our biggest challenges — we started with very ambitious goals, but quickly realized the importance of prioritization and iterative design. By starting simple and building up, we managed to deliver a functional and elegant solution under time pressure.
