2WD DIY Aluminum Alloy Smart Robot Car Chassis Kit – 6V 250RPM Motors with 64.5mm Wheels

Product Description

The 2WD DIY Aluminum Alloy Smart Robot Car Chassis Kit is a durable and versatile robotic platform designed for students, hobbyists, makers, and developers building custom mobile robots. Manufactured from aluminum alloy, the chassis provides a rigid and stable foundation for robotics, automation, educational, and IoT projects.

The aluminum construction offers greater mechanical strength compared with many standard acrylic robot chassis while maintaining a lightweight design. The purple anodized finish provides a professional appearance along with resistance to surface oxidation and wear.

The chassis includes multiple mounting holes, making it easy to install Arduino boards, Raspberry Pi boards, ESP32 development boards, sensors, batteries, and motor drivers. Its no-soldering DIY design makes mechanical assembly straightforward and allows users to focus on programming and robotics development.

The kit includes two 6V DC gear motors rated at approximately 250 RPM, paired with 64.5mm high-traction wheels. The 2WD configuration provides simple control, good maneuverability, and sharp turning capability for indoor robotic applications. A universal caster wheel supports the rear or front section of the chassis and helps maintain stability during movement.

Specifications

Design and Construction

The chassis is manufactured from aluminum alloy to provide a rigid mechanical platform for the robot’s motors and electronics. The material helps reduce flexing and provides improved durability for repeated assembly and use.

The purple anodized surface finish provides a distinctive appearance and helps protect the aluminum surface against oxidation and general wear.

Multiple mounting holes are provided throughout the chassis, allowing users to install different controllers, batteries, sensors, and accessories according to their project requirements.

The chassis is designed for simple mechanical assembly and does not require soldering for the basic mechanical construction.

Working Principle

The robot uses a 2-wheel-drive configuration, with one geared motor driving each main wheel.

The two motors can be controlled independently using a suitable motor driver:

• Both motors forward → Robot moves forward
• Both motors reverse → Robot moves backward
• One motor faster than the other → Robot turns
• One motor forward and the other reverse → Robot can pivot

The caster wheel provides additional support and helps the chassis move smoothly during turns.

A microcontroller such as Arduino, ESP32, or Raspberry Pi can be used with a suitable motor driver to control the two motors.

Motor and Wheel System

The kit includes two 6V DC gear motors with a rated speed of approximately 250 RPM.

The motors are paired with 64.5mm high-traction wheels, providing a practical balance between speed, traction, and maneuverability for indoor robotic platforms.

The motor speed and torque at the wheel depend on the actual motor load, battery voltage, driver characteristics, and surface conditions.

Mounting and Expansion

The chassis provides mounting space for a variety of robotic components, including:

• Arduino boards
• ESP32 boards
• Raspberry Pi boards
• Motor drivers
• Ultrasonic sensors
• LiDAR sensors
• Line-following sensors
• Cameras
• Battery packs
• Wireless modules
• Servo motors
• Other electronic modules

This makes the platform easy to customize for different robotics applications.

Product Disclaimer

Product images are shown for illustrative and representational purposes only. The actual chassis, motors, wheels, caster, colour, dimensions, surface finish, and hardware may vary slightly depending on the manufacturing batch and supplier.

Arduino, ESP32, Raspberry Pi, motor driver, sensors, batteries, wiring, and other electronic components shown in product images are not included unless specifically mentioned in the package contents.

Actual motor speed and performance depend on supply voltage, load, motor driver, battery condition, surface type, and mechanical assembly.

Important Notes

Motor Driver Required

The kit includes the motors but does not include a motor driver. A suitable motor driver such as an L298N, MX1919, or equivalent is required to control the motors.

Power Supply

Use a suitable power source compatible with the 6V motors and selected motor driver. Ensure the power source can provide sufficient current for both motors under load.

Assembly

The kit is supplied as a DIY mechanical assembly. Properly tighten all screws and standoffs before operating the robot.

Caster Wheel

The caster wheel provides mechanical support and helps maintain chassis stability during movement and turning.
