BlueBot

BlueBot is a two-wheel robot built using an Arduino Uno and controlled wirelessly via Bluetooth. This project was created as part of a student comprehensive examination in the engineering physics course to explore hands-on electronics, microcontroller programming, and Bluetooth communication. The robot can drive in four directions and is operated using simple commands sent from a phone or computer.

It uses an Arduino Uno compatible board, an L298N H-Bridge motor driver to control two DC motors, an HC-05 Bluetooth module for wireless input, and it is all assembled on an MDF laser-cut robot chassis with jumper wires (male-to-female). Power is supplied by a 9V battery to keep the robot mobile and untethered.

Made by:

• Myles Elman
• Justin Ferreira

⚙️ How It Works

1. Power the Arduino using a 9V battery via the barrel jack.
2. Connect to the HC-05 module using a Bluetooth terminal on a computer (iPhone not supported).
3. Send the following single-letter commands:
   • F – Forward
   • B – Backward
   • L – Turn Left
   • R – Turn Right

✅ Project Highlights

• Fully wireless movement via Bluetooth
• No breadboard or resistors needed in final design
• Compact and efficient layout with minimal wiring
• Successfully tested on different indoor surfaces
• Powered entirely by a single 9V battery

🔧 To Do

• Add ultrasonic sensor for obstacle detection
• Upgrade to HC-10 or BLE module for full device compatibility
• Add wheel encoders for more precise steering
• Develop a custom mobile app interface
