4Pair- YELLOW Plastic Gear Motor & 65mm Wheels DC 3V-6V 130RPM Gear Motor Dual Shaft Smart Robot Car Wheels D65mm Robotic Wheels

4Pair Yellow Plastic Gear Motor & 65mm Wheels Combo Set (4 Motors + 4 Wheels) is a high-performance 4-wheel drive (4WD) power transmission set engineered for heavy-duty, multi-terrain robotics chassis. Combining four 3V-6V DC dual-shaft TT gear motors and four matching high-traction 65mm soft rubber tire wheels, this kit delivers maximum torque, ground clearance, and all-wheel propulsion. It is the ideal setup for building 4WD autonomous mobile robots, obstacle-climbing smart cars, and heavy-payload DIY robotic platforms.

Features

• Complete 4WD propulsion set: includes 4 x dual-shaft TT DC gear motors and 4 x 65mm rubber-tire wheels
• Dual-ended output shaft on every motor allowing simultaneous wheel and optical speed encoder disc installation
• High-torque 1:48 internal spur gear reduction delivering reliable 130–200 RPM output speed
• High-traction 65mm wheels with flexible soft rubber tires for superior surface grip and shock absorption
• Precision press-fit double-flat (D-shaft) wheel hub design for non-slip torque transfer
• Durable, high-impact plastic housing with integrated mounting holes for direct chassis attachment
• Fully compatible with standard dual H-bridge motor drivers (L298N, L293D, MX1508) and popular microcontrollers (Arduino, ESP32, Raspberry Pi)
• Internal EMC magnet design minimizes electromagnetic interference on sensitive control circuitry

Applications

• 4WD autonomous smart robot car chassis (Arduino, ESP32, ESP8266, Raspberry Pi driven)
• All-terrain obstacle-avoidance, maze-solving, and heavy-payload mobile robots
• Precision speed-controlled smart rovers using slotted 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:

• Drive all four motors using a dual H-bridge motor driver (such as 2 x MX1508 modules or 1 x L298N motor driver) to handle combined load current safely.
• Always supply motors with a dedicated battery source (e.g., two 18650 Li-ion batteries in series) to avoid brownouts and resets on the main microcontroller.
• Align and press wheels straight onto the D-shafts carefully; applying uneven side-impact force can snap the plastic motor shafts.
• Apply quick soldering techniques at medium temperature when attaching lead wires to prevent softening or melting the plastic casing near terminal leads.
• Keep rubber tires free from dust and oil to maintain optimal traction on smooth or tiled surfaces.

Package includes

• 4 x 3V-6V DC Yellow Dual-Shaft TT Gear Motors
