The OpenELAB team has developed a mini tank robot equipped with a programmable processor that utilizes the Arduino Integrated Development Environment (IDE). This design integrates a shield that connects to the processor, enabling the mapping of pins to various sensors and actuators. The robot is capable of reading sensor inputs, controlling the actuators, and making informed operational decisions.

The system is designed to perform a range of functions, including obstacle avoidance, infrared remote control, Bluetooth management, and light-following capabilities, among others.

This resource presents a comprehensive guide comprising fifteen detailed learning projects, ranging from fundamental to advanced levels, aimed at facilitating the development of a smart mini-tank robot. It also imparts essential knowledge regarding various sensors and modules. Furthermore, it serves as an excellent option for educational endeavors in graphical programming.

Features

• Light Tracking Function: The light sensor automatically detects the direction with stronger light and moves towards the light source.

• Infrared Remote Control: The car can be controlled by a remote controller, making it simple and convenient to operate.

• Obstacle Avoidance Function: Ultrasonic sensors detect obstacles in front of the car to avoid collisions and can also measure the distance to the obstacle.

• Bluetooth Control: The car can be controlled via a mobile app connected through Bluetooth, ensuring fast connection, convenient operation, and comprehensive functionality.

• Object Following Function: The mobile app connects via Bluetooth, enabling the car to follow objects in front.

• Display Icons: The car’s driving status is shown with different icons, indicating forward, backward, left turn, right turn, and other actions.
