This modular Mecanum Wheel Aluminum Alloy 4WD Smart Car Chassis Kit offers a robust and expandable platform for DIY robotics and Arduino development. Available in both single-layer and double-layer configurations, each chassis is constructed from precision-machined aluminum alloy for structural strength and stability. The included 60mm injection-molded Mecanum wheels provide omnidirectional movement, ideal for advanced navigation and control experiments.

Customers can choose between two options for each chassis type:

• Basic Kit (Chassis + Motors + Wheels)
• Full Kit (Chassis + Motors + Wheels + All Electronics & Cables)

The full kit includes an Arduino-compatible UNO board, motor driver module (L298N), ultrasonic distance sensor (HC-SR04), tracking module, servo motor, and other essential components for building a complete intelligent obstacle avoidance system. This product is ideal for learners and developers seeking to deepen their understanding of microcontroller-based robotics.
