2WD Arduino Bluetooth Controlled Robot Kit (Unassembled) – DIY Smart Car Kit

Description

Build Your Own Smartphone-Controlled Robot

The 2WD Arduino Bluetooth Controlled Robot Kit is an all-in-one DIY project designed for students, educators, and hobbyists looking to learn embedded systems, robotics, and mobile wireless communication.

This kit comes completely unassembled, giving you hands-on experience in mechanical chassis assembly, circuit wiring, and C/C++ programming for Arduino.

Key Features:

• Smartphone Control: Wirelessly control robot movement (Forward, Reverse, Left, Right, Stop) via any free Android/iOS Bluetooth terminal or custom MIT App Inventor application.

• Open-Source & Expandable: Powered by the Arduino Uno platform—easily add ultrasonic distance sensors, line-tracking modules, or IR sensors for autonomous navigation.

• Heavy-Duty Motor Control: Includes the reliable L298N Dual H-Bridge motor driver for precise motor speed (PWM) and directional management.

• Durable Acrylic Chassis: Comes pre-cut with mounting slots for boards, battery holders, switches, and extra sensors.

Package Includes (Box Contents):

• 1 x 2WD Acrylic Smart Robot Car Chassis Plate

• 2 x Dual-Shaft Geared DC Motors (3–6V)

• 2 x High-Traction Rubber Wheels

• 1 x Front Universal Caster Wheel

• 1 x Arduino Uno R3 Development Board (with USB Cable)

• 1 x HC-05 / HC-06 Wireless Bluetooth Module

• 1 x L298N Dual H-Bridge Motor Driver Module

• 1 x Battery Holder / Case

• 1 x Set of Premium Jumper Wires (Male-to-Female & Male-to-Male)

• Complete Mechanical Fasteners (Screws, Nuts, and Standoffs)

Technical Specifications:

• Platform Type: 2-Wheel Drive (2WD) Differential Steering

• Microcontroller: ATmega328P (Arduino Uno Compatible)

• Motor Driver: L298N Dual H-Bridge

• Operating Voltage: 6V – 12V DC

• Wireless Protocol: Bluetooth v2.0 + EDR (HC-05 Module)

• Wireless Range: Approx. 10 meters (33 feet)

• Assembly Skill Level: Beginner to Intermediate

How It Works:

1. Assemble the acrylic frame and mount the motors, wheels, and caster wheel.

2. Wire the motors to the L298N driver, connecting the logic pins to the Arduino Uno and the HC-05 Bluetooth module to serial pins.

3. Upload the provided sample Bluetooth control code via the Arduino IDE.

4. Pair your smartphone with the HC-05 module and use any standard Bluetooth RC Controller App to drive your robot!
