4WD Smart Robot Car Chassis Kit refers to a robotics kit that provides the basic framework for building a smart, four-wheel-drive (4WD) robot car. It typically includes a chassis (the frame), wheels, motors, and other mechanical components required to assemble the car, but may not include the electronics or sensors for full functionality.
4WD Chassis: The base frame of the robot, designed to hold the motors and wheels in place. The "4WD" part refers to the fact that all four wheels are driven by motors, providing better traction and stability compared to two-wheel-drive robots.
Motors and Wheels: Four motors (usually DC motors) that drive the wheels. These motors are often equipped with encoders or simple control circuits to allow the robot to move in different directions.
Frame/Structure: A lightweight frame, usually made of plastic, metal, or acrylic, that holds the motors, wheels, and other components in place. It’s designed to be sturdy enough to support additional components like sensors and batteries.
Battery Holder: A space or holder for placing the power source, like a battery pack (often a Li-ion or AA batteries).
