With two L298N motor drivers and Arduino's PWM, you command each side independently for sharp turns and smooth acceleration. The HC-SR04 ultrasonic sensor gives it autonomous obstacle avoidance, making it a great platform for robotics competitions and college projects.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll build a fully functional 4WD robot chassis powered by rechargeable 18650 cells. It drives forward, backward, and pivots in place, while the front-mounted ultrasonic sensor scans for obstacles and automatically steers clear. Once assembled, you can program it for line-following, remote control, or maze-solving - the chassis is a blank canvas for advanced robotics.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eProgram Arduino Uno for PWM speed control of TT gear motors\u003c\/li\u003e\n  \u003cli\u003eWire dual L298N motor drivers to power four motors\u003c\/li\u003e\n  \u003cli\u003eIntegrate HC-SR04 ultrasonic sensor for obstacle detection and avoidance\u003c\/li\u003e\n  \u003cli\u003eDebug power distribution with diodes, capacitors, and battery protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Uno R3\u003c\/td\u003e\n\u003ctd\u003ex1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHC-SR04\u003c\/td\u003e\n\u003ctd\u003ex1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eL298N Motor Driver\u003c\/td\u003e\n\u003ctd\u003ex2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTT Gear Motor\u003c\/td\u003e\n\u003ctd\u003ex4\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e4WD Chassis\u003c\/td\u003e\n\u003ctd\u003ex1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e18650 Cell\u003c\/td\u003e\n\u003ctd\u003ex2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e18650 Holder\u003c\/td\u003e\n\u003ctd\u003ex1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e10k?
