The DIY 2-Wheel Wooden Chassis Robotic Car Kit is a versatile educational platform designed for students, educators, hobbyists, and robotics enthusiasts. Crafted from premium high-density laser-cut wood, the chassis offers an eco-friendly, easy-to-customize alternative to acrylic or metal chassis plates. The wood surface allows easy drilling, gluing, painting, and mounting of various sensors, microcontrollers, and motor drivers.

The kit includes two high-torque $3\text{V}-6\text{V}$ Dual-Shaft BO (Battery Operated) DC Gear Motors equipped with durable rubber-tread wheels for maximum traction on smooth surfaces. A low-friction omnidirectional front caster wheel provides smooth 360∘ differential steering and rotation. Pre-cut mounting slots allow seamless integration of popular microcontrollers (Arduino Uno, ESP32, Raspberry Pi Pico), motor drivers (L298N, L293D), ultrasonic distance sensors, line-tracking sensor arrays, and servo motors.

Key Features and Benefits

• Durable & Customizable Wooden Base Plate: Precision laser-cut wood with pre-drilled mounting slots for boards, sensors, switches, and battery holders.

• Dual High-Torque BO Gear Motors: $3\text{V}-6\text{V}$ DC gear motors supply efficient power and speed for indoor robotic navigation.

• Omnidirectional Front Caster Wheel: Smooth 360∘ swivel caster ensures smooth differential turning and balanced 3-point contact.

• High-Grip Rubber Wheels: $65\text{mm}$ wheels with textured rubber tires deliver excellent surface traction and shock absorption.

• Complete Assembly Hardware Included: Ships with motor mounting brackets, brass standoffs, nuts, bolts, and a $4\times \text{AA}$ battery holder.

• Ideal STEM & Educational Tool: Excellent hands-on kit for learning basic electronics, soldering, motor control, and embedded programming.
