Complete DIY Science Project Kit: Build an Arduino Bluetooth Robot Car with ESP32 Live WiFi Camera

Dive into the exciting world of robotics with the complete DIY Smart Robot Car kit from Bigyan Project. This comprehensive science project is engineered for students, hobbyists, and future innovators in Bangladesh looking for a hands-on experience with Arduino, electronics, and programming. This isn't just a toy; it's a fully functional robotic platform that you build from the ground up. You can navigate your surroundings using a live, first-person video stream directly from the onboard ESP32-CAM to your phone or computer. Control the robot's every move with a custom Android app via the stable HC-06 Bluetooth connection. Furthermore, we have integrated an intelligent obstacle avoidance system using an HC-SR04 ultrasonic sensor mounted on a 180° servo, allowing the robot to autonomously detect and navigate around objects. Powered by a robust 3S 18650 battery system with a modern Type-C charging board, this project provides a reliable and rechargeable power solution. Assembled on a durable 4-wheel PVC chassis, this robot car is the ultimate educational tool for learning about motor control, sensor integration, and wireless communication, making it a premier choice for any tech enthusiast's collection.

4. Control: Power on the robot. Connect your Android smartphone to the HC-06 Bluetooth module using a compatible robotics control app.
5. Live View: Connect your phone or computer to the WiFi network created by the ESP32-CAM. Open the streaming address in a web browser to see the live video feed.
6. Operation: Use the mobile app to drive the robot. Activate the obstacle avoidance mode to let the robot navigate autonomously.

Frequently Asked Questions (FAQs)

• Q: Is programming knowledge required to build this robot?
  A: Yes, basic knowledge of Arduino C++ programming is necessary to understand, upload, and modify the code. Our kit at বিজ্ঞান প্রজেক্ট is designed to help you learn along the way.
• Q: Can I control the robot from an iPhone?
  A: The included HC-06 Bluetooth module is primarily designed for Android devices. iOS compatibility would require a different Bluetooth module (like BLE).
• Q: What is the control range of the robot?
  A: The Bluetooth control range is typically around 10 meters (about 30 feet) in an open area. The WiFi video stream range depends on the ESP32-CAM's signal strength.
• Q: How long do the batteries last on a full charge?
  A: Runtimes vary based on usage, but a fully charged set of quality 18650 batteries should provide over an hour of continuous operation.

Challenges and Considerations

• Power Management: Supplying 11.1V-12.6V from the batteries to the L298N driver requires careful speed control via PWM in the code to avoid damaging the 3-6V motors.
• Dual Microcontroller Setup: Managing code and communication for two separate boards (Arduino for control, ESP32 for video) requires careful planning and wiring.
• Wiring Complexity: The project involves numerous components and connections. A clear understanding of the circuit diagram is essential for successful assembly.

Compatibility

• Software: Fully compatible with the official Arduino IDE for programming the Arduino Uno and ESP32-CAM.
• Operating System: The Bluetooth control function is designed for Android OS. The WiFi video stream is accessible from any device with a modern web browser (Android, iOS, Windows, macOS).
• Components: All included parts are standard hobbyist electronics, making them easy to replace or upgrade.

Future Enhancement Options

• Unified Control: Migrate all functions (control, sensors, video) to the powerful ESP32 board to simplify the design.
• Add More Sensors: Integrate line-following sensors for autonomous navigation on a track or an IMU sensor for stability control.
• Robotic Arm: Attach a small robotic arm to add object manipulation capabilities.
• Cloud Integration: Connect the ESP32-CAM to the internet to stream video and control the robot from anywhere in the world.

Benefits

• Practical Learning: Gain real-world skills in robotics, embedded systems, and wireless communication.
• All-in-One Solution: This kit provides every essential electronic and mechanical part needed, saving you the hassle of sourcing individual components.
