DIY 4-Wheel Drive Smart Robot Car Chassis Kit with Motors & Speed Encoders

✔ 4-Wheel Drive Smart Car Platform – A solid DIY base for building RC cars, line-following robots, obstacle-avoiders, and custom robotics projects. Comes with wheels, motors, chassis plates, and all mounting hardware.

✔ High-Torque DC Gear Motors – Equipped with four deceleration DC motors that offer strong torque and stable movement. Operates on 3V–6V power with a no-load speed of around 200 RPM at 6V.

✔ Easy Mechanical Assembly – Simple structure designed for beginners and hobbyists. The chassis is stable, durable, and easy to expand with sensors, servos, controllers, and add-on modules.

✔ Includes Speed Encoders – Supports accurate speed measurement and movement control, making it ideal for advanced robotics experiments and coding projects.

✔ Universal Caster Wheel – Front caster prevents slippage and ensures smooth turns and directional stability.

✔ Fully Expandable Robotics Platform – Features mounting slots for different sensors, Arduino boards, Raspberry Pi, motor drivers, servos, and more. Perfect for STEM learning and maker projects.

✔ Complete Kit – Comes with chassis plates, 4 motors, 4 wheels, battery holder (4×AA), universal caster, screws, nuts, and required brackets.
