The 4-Wheel Drive (4WD) Smart Robot Car Chassis Kit is a powerful and stable platform designed for advanced robotic projects. At Electrapac, we recommend this 4WD version over the 2WD model for users who require higher payload capacity, better traction, and a more robust base for complex sensors and mechanical arms.

Product Overview

This kit features a double-layer High-Strength Acrylic Chassis design, providing ample space to mount your electronics on the bottom and your sensors or batteries on the top. Equipped with four independent DC Geared Motors (BO Motors), this chassis offers true 4-wheel drive capability, allowing the robot to handle rougher indoor terrain and carry more weight without compromising speed or maneuverability.

Key Features for Electrapac Customers

• Double-Layer Expansion: The two-tier design allows you to isolate your power systems (batteries/motors) from your logic systems (Arduino/Raspberry Pi), reducing electrical noise and clutter.

• 4-Motor Power: With four independent motors, you can implement skid-steer turning or high-torque movement, making it much more stable than 3-wheel or caster-wheel designs.

• Pre-Drilled Precision: The laser-cut acrylic plates include universal mounting slots for Arduino Uno, Mega, L298N Motor Drivers, and HC-SR04 Ultrasonic Sensors.

• Speed Monitoring Ready: Includes four slotted encoder disks. By adding photo-interrupter sensors, you can track the speed and distance of each individual wheel for precision navigation.

• Complete Hardware Kit: Includes all necessary brass standoffs, screws, and nuts required to assemble the dual-layer structure.

What’s in the Box?
