The "Smart 4 Drive" robot is a programming toy that uses modular integration. Players can build a robot framework with different functions by purchasing the parts they need. The overall shell uses streamlined curved surfaces to wrap the original bulky components, and is decorated with LEDs to depict a surreal sci-fi chariot. Players can add various sensors to it... Do you want to try to build your own robot car? Now DFRobot have this complete basic kit for you. By adding Romeo all-in-one main controller, ultrasonic obstacle avoidance sensor and power supply to Cherokee, and then burning a simple program, the car can realize the function of automatic obstacle avoidance. With detailed tutorials, you don't have to worry about learning. The main controller adopts the new version of Bluno Romeo, which integrates Arduino UNO R3, motor drive, IO sensor expansion board and Bluetooth 4.0 communication module, and has all the basic functions of the robot. Therefore, players can add various sensors to it, which has more learning potential. The interior of the fuselage is made of high-strength aluminum alloy material, and the high-speed motor brings more flexible movement. The shell can be made by the user by using the 3D printer after downloading the 3D data. Some DIY modules can be modified or color matching according to the needs of the user, so as to meet the personalized needs to a greater extent.
