The 2-Wheel Drive (2WD) Smart Robot Car Chassis Kit is the ultimate foundation for your journey into robotics. At Electrapac, we recommend this kit for students, educators, and hobbyists who want to build anything from a simple line-following robot to a complex Wi-Fi-controlled explorer.

Product Overview

This universal robotic platform features a high-quality, transparent Acrylic Chassis that is both lightweight and durable. The kit includes two independent DC Gear Motors for driving the rear wheels and a smooth-rolling Omni-directional Caster Wheel for the front, allowing for zero-turn radius and incredible maneuverability. With pre-drilled mounting holes, it is perfectly designed to hold an Arduino Uno, L298N Motor Driver, and various sensors without the need for additional drilling.

Key Features for Electrapac Customers

• Complete Mechanical Set: Includes everything you need to get rolling: chassis, motors, wheels, speed encoder disks, and a battery box.

• Integrated Speed Encoders: The kit comes with two slotted encoder disks. When paired with an infrared tachometer sensor, you can measure the RPM and distance traveled by your robot.

• Modular Mounting: The laser-cut holes are specifically spaced for Arduino Uno, Mega, and Raspberry Pi, as well as standard motor drivers and ultrasonic sensors.

• High-Grip Rubber Tires: The 65mm wheels feature soft rubber tires with deep treads, ensuring excellent traction on tiles, wood, and flat surfaces.

• Independent Power: Includes a 4-cell AA battery holder (batteries not included) to provide independent power to your motors, preventing your microcontroller from resetting.
