2Pair- YELLOW Plastic Gear Motor & 65mm Wheels DC 3V 6V 130RPM Gear Motor Dual Shaft Smart Robot Car Wheels D65mm Robotic Wheels

2Pair Yellow Plastic Gear Motor & 65mm Wheels Combo Set (2 Motors + 2 Wheels) is a balanced 2-wheel drive (2WD) propulsion kit designed for hobbyist, student, and competitive robotics projects. The set combines two 3V-6V DC dual-shaft TT gear motors with two high-traction 65mm soft rubber tire wheels. Engineered for fast assembly and seamless integration with standard acrylic robot car chassis, it provides smooth differential steering and reliable movement for line followers, obstacle-avoiding cars, and Bluetooth/Wi-Fi remote-controlled rovers.

Features

• Complete 2WD propulsion set: includes 2 x dual-shaft TT DC gear motors and 2 x 65mm rubber-tire wheels
• Dual-ended output shaft on every motor for simultaneous wheel and optical speed encoder disc mounting
• High-torque 1:48 internal gear reduction layout delivering stable 130–200 RPM output speed
• High-traction 65mm wheels with soft rubber tread tires for excellent surface grip and vibration reduction
• Press-fit double-flat (D-shaft) wheel hub mounting for secure, non-slip power transmission
• Compact, lightweight, high-impact plastic housing designed for quick installation on 2WD smart car chassis
• Fully compatible with standard H-bridge motor drivers (L298N, L293D, MX1508) and microcontrollers (Arduino, ESP32, Raspberry Pi)
• Built-in EMC magnet design to suppress electromagnetic noise and protect control circuits

Applications

• 2WD autonomous smart robot car chassis (Arduino, ESP32, ESP8266, Raspberry Pi driven)
• Line-following, maze-solving, and obstacle-avoiding mobile robotics platforms
• Speed-controlled smart rovers utilizing optical wheel encoder discs
• Wireless remote-controlled (RC) vehicles operating via Bluetooth, Wi-Fi, or NRF24L01
• STEM robotics education kits, polytechnic diploma coursework, and university engineering thesis projects

Important Notes:

• Always drive both motors using a dual H-bridge motor driver (such as L298N, L293D, or MX1508); never connect motor leads directly to microcontroller GPIO pins.
• Ensure a dedicated battery power source (e.g., two 18650 Li-ion batteries or 4 x AA battery holder) for the motor driver to prevent controller reset issues.
• Press the wheels squarely onto the motor D-shafts without applying force to avoid snapping the output shafts.
• Solder motor leads quickly with medium heat to prevent melting the plastic casing near the terminals.
• Keep the rubber tires clean of dust or oily residues to maintain optimal traction on smooth indoor surfaces.

Package includes

• 2 x 3V-6V DC Yellow Dual-Shaft TT Gear Motors
• 2 x 65mm Yellow Plastic Wheels with Soft Rubber Tires
