The detail of the original product is as following:

Most Advanced Technology in the Market Today: the OSOYOO Robot Car kit features a servo power steering motor that controls the axles to turn the wheels. This electric power steering system enables a highly automated driving experience that imitates real-world full-sized vehicles Do-it-yourself Starter Robot Car Building Kit: allows adults, teens, and all students to learn valuable skills, fully compatible with Arduino UNO R3 board, it will help you learn about electronic circuits, programming sensors and actuators, the Internet of Things (IoT), coding, electronics, mechanical engineering and hands-on experience in robotics Package includes all the technical modules, parts, and sensors you need to build a fully functional robotic car: such as MCU board for R3, OSOYOO motor shield, OSOYOO ESP8266 WIFI shield, HC Bluetooth module, line tracking module, ultrasonic sensor, micro servo motor, battery, and charger Multifunctional and features all the highly advanced intelligent features and driving modes that you expect for a robot car: which includes: auto-go, line tracking, ultrasonic avoidance, Wifi IOT control, Bluetooth App control, compatible with Android and Apple IOS devices via an app developed in house exclusively for OSOYOO Step-by-step instructions, videos, and tutorials will show you detailed instructions on installing your new robotic car, with easy-to-understand circuit graphs, sample code, demo videos, and North American-based product support

WIFI IoT Controlled

OSOYOO ESP8266 WiFi Module integrates with Arduino Internet of Things (IoT) prototyping and learning modules. Support different Internet of Things protocols, including HTTP, UDP, MQTT, etc. We developed Apple iOS and Android apps for this robot kit. We optimized it to integrate with the robot car based on WiFi. You can rely on the app to control the robot through your iOS or Android device.

Universal Bluetooth Compatibility

Use the app to control your robot car with Bluetooth through any iOS or Android device. Share the experience with your kids, family, or friends; the app provides a virtual steering wheel and gear that allows you to imitate real-world driving.

Smart Obstacle Avoidance Feature

A cool and innovative feature, the OSOYOO robot smart car will automatically detect obstacles in front of it through the integrated sensors in any direction. The sensors send ultrasonic waves and calculate the distance, keeping your car away from a collision.

Loads of Fun with Line Tracking

The line tracking modules consist of sensors at the bottom of the car; you can program it to follow the track/line you designed. The system works with its infrared transmitter tube and an infrared receiver tube. Simply mark your track as a line on a flat surface, start the car and prompt it to follow the track; you can even make it race another robot car to see which one reaches the finish line first.
