Build, code, and drive your own smart robot car with this all-in-one STEM kit. Features ESP32 control board with built-in motor driver, Bluetooth, Wi-Fi, and multiple sensor interfaces. Includes 7 step-by-step tutorials from basic assembly to IoT control.
The All-in-One Robot Learning Kit You've Been Looking For
The OSOYOO Espro 2WD Mini Smart Robot Car Kit is a complete STEM learning platform designed for beginners, educators, and robotics enthusiasts. At its heart is the OSOYOO ESP32 Motor Driver Board – a credit-card-sized all-in-one control board that integrates an ESP32 microcontroller, L293DD dual H-bridge motor driver, Bluetooth, and Wi-Fi on a single PCB. No stacking shields, no messy wiring, no compatibility issues.
What Can You Build?
This kit comes with 7 detailed tutorials that guide you from assembly to advanced projects:
-
Line Following – Use the 5-channel infrared sensor array to follow black lines on white surfaces with real-time direction adjustments
-
Obstacle Avoidance – Ultrasonic sensor with servo motor scans 180° to detect and navigate around obstacles
-
Object Following – IR sensors track and follow moving objects automatically
-
MPU6050 Navigation – Add a gyroscope for precise movement control and self-balancing (MPU6050 sold separately)
-
Bluetooth Control – Connect to the OSOYOO Imitation Driving APP for a realistic driving experience with virtual steering wheel and gear controls
-
Wi-Fi IoT Control – Connect your car to Wi-Fi and control it from anywhere using the OSOYOO IoT UDP Robot APP
-
Maze Solving – Combine sensors for autonomous maze navigation
Easy Programming
Program the ESP32 directly using Arduino IDE – the most popular platform for makers and educators. The USB-C port with auto-download circuit means no manual button pressing during upload. All tutorials are Arduino IDE-based, making programming accessible even for absolute beginners.
Perfect for STEM Education & Home Learning
Whether you're teaching robotics in the classroom, introducing coding to your kids, or building your first robot at home, this kit grows with your skills. From basic motor movement to complex autonomous behaviors and IoT integration, you'll gain authentic hands-on experience with real hardware.
