: Modular 4WD Arduino RC Chassis - High-Strength Robotics Frame

This is a professional-grade mechatronics chassis designed for Arduino-based robotics. The kit includes the main structural chassis, protective side covers, and a top mounting plate—all featuring pre-aligned holes for an Arduino Uno/Mega, L298N motor driver, and 4x standard yellow TT motors. Unlike basic frames, this design protects your internal electronics from debris while providing ample mounting points for sensors like the HC-SR04 ultrasonic module
