Modular Track Chain Kit – 50-Piece Robot Tank Track with 84mm Nylon Wheels

Product Description

The Modular Track Chain Kit is a versatile caterpillar-track system designed for DIY robots, robotic chassis, RC tanks, mobile platforms, and educational robotics projects. It replaces conventional wheels with a tracked drive system, providing a practical solution for building mobile robots that require stable movement across flat surfaces and light obstacles.

The kit includes 50 individual plastic track links that interlock to form an approximately 1-meter-long track section. The modular design allows users to add or remove links to adjust the track length according to the dimensions of their robotic chassis.

The track links are manufactured from high-quality industrial plastic, providing a lightweight and rigid structure while allowing smooth movement around the drive wheels. The modular construction also makes the track easy to assemble, repair, and customize for different robot designs.

The kit includes four 84mm diameter virgin Nylon wheels with approximately 6.1mm center holes, designed to fit compatible 6mm motor shafts. Each wheel includes a shank and locking screw to provide a secure connection to the motor shaft and help reduce slipping during operation.

The combination of modular track links and nylon drive wheels makes this kit suitable for building tracked robots, surveillance platforms, all-terrain vehicles, warehouse prototypes, RC tanks, and other custom robotic chassis.

Specifications

Design and Construction

The Modular Track Chain Kit uses a series of individual plastic links that interlock to create a continuous caterpillar track.

Each link measures approximately 3 × 2 cm, and the supplied 50 links provide a total track length of approximately 1 meter. The modular construction makes it possible to customize the track according to the required chassis size by adding or removing individual links.

The four 84mm Nylon wheels provide a durable and lightweight drive structure. Their 6.1mm center holes are designed for compatible 6mm motor shafts, while the included locking screws help secure the wheels to the drivetrain.

The plastic and Nylon components are designed for low-maintenance use and do not normally require lubrication under typical operating conditions.

Working Principle

The track system works by transferring rotational motion from the robot’s geared motors to the drive wheels.

As the motor rotates the wheels, the wheels engage with the interlocking track links and move the continuous track around the chassis. This creates forward, reverse, and turning movement for the tracked robot.

For differential-drive robots, the left and right tracks can be driven independently. Increasing the speed of one side or reversing one side allows the robot to turn, pivot, or rotate in place.

The modular track design allows the user to customize the length and adapt the system to different robotic chassis dimensions.

Modular Track System

The track is made from 50 individual links, allowing the overall length to be modified according to the project’s requirements.

Users can:

• Add additional links for a longer chassis
• Remove links for a more compact robot
• Replace individual damaged links
• Customize the track length for different wheel spacing

This modular construction makes the track kit useful for experimentation and custom robot development.

Wheel and Motor Compatibility

The included wheels have a 6.1mm shaft hole and are intended for compatible motor shafts around 6mm diameter.

The included locking screws help secure the wheel to the shaft. Before assembly, verify the motor shaft diameter, shaft length, flat section if applicable, and screw arrangement to ensure proper mechanical compatibility.

Motors and gearboxes are not included in this kit unless specifically mentioned in the package contents.

Typical Application Scenarios

Mobile Surveillance Robots

The tracked chassis can provide a stable mobile platform for surveillance cameras, AI vision systems, and remote monitoring equipment.

Product Disclaimer

Product images are shown for illustrative and representational purposes only. The actual product may vary slightly in colour, dimensions, surface finish, link appearance, wheel colour, screw design, or other visual details depending on the manufacturing batch and stock availability.

Motors, gearboxes, chassis plates, batteries, controllers, sprockets, tools, and other robotic components shown in product images are not included unless specifically mentioned in the package contents.

The supplied track length is approximate and may vary slightly due to link arrangement and assembly configuration.

Important Notes

Track Assembly

When assembling the plastic track links, make sure all connecting pins are fully seated and properly secured before operating the robot.

Preventing Link Separation

The pin at one end of the track may need to be secured with suitable adhesive or slightly bent where appropriate to help prevent the pin from sliding out during operation.

Do not apply excessive force while bending or modifying the pins, as this may damage the track links.

Motor Compatibility

The wheels are designed for approximately 6mm motor shafts. Check the motor shaft size before purchase and assembly.

Track Tension

Maintain suitable track tension during installation. Excessive tension can increase motor load and mechanical wear, while insufficient tension may cause the track to disengage from the wheels.

Load and Surface Conditions

Actual performance depends on robot weight, motor torque, wheel spacing, track tension, surface type, obstacle size, and battery power.
