2WD Arduino Bluetooth Controlled Robot (Unassembled)

Overview

The 2WD Arduino Bluetooth Controlled Robot (Unassembled) is a beginner-friendly robotics kit that combines Arduino programming, motor control and wireless communication. With Bluetooth connectivity and an Arduino UNO controller, this kit lets you control a two-wheel drive robot from a smartphone, tablet or computer. It is ideal for students, hobbyists and educators who want hands-on experience with robotics and IoT projects.

Key Features

• Bluetooth controlled operation using HC-05 for wireless commands from mobile apps
• Arduino UNO R3 based open-source platform for easy coding and customization
• L298N motor driver module for stable H-bridge control of two DC gear motors
• Strong transparent acrylic chassis to mount electronics securely
• 2WD platform with geared DC motors and high-traction rubber wheels for good maneuverability
• Expandable design compatible with ultrasonic, IR and other sensors for autonomous functions

Specifications

• Controller Board: Arduino UNO R3
• Motor Driver: L298N Module
• Communication: Bluetooth HC-05
• Power Supply: 2 x 18650 Li-ion batteries
• Chassis Type: 2WD Acrylic Robot Platform
• Motors: 2 x DC Gear Motors (3-12V)
• Wheels: High-traction rubber wheels
• Caster Wheel: 1 x Universal caster wheel

How It Works

1. Pair the HC-05 Bluetooth module with your smartphone.
2. Open a Bluetooth controller app from the Play Store or App Store.
3. Use on-screen directional buttons to send movement commands.
4. The Arduino UNO reads serial commands and uses the L298N motor driver to drive the motors accordingly.
