Pololu Tamiya 70093 3-Speed Crank-Axle Gearbox Kit

The Tamiya 3-speed crank-axle gearbox offers versatile functionality with the ability to configure it in three different gear ratios: 17:1, 58:1, and 204:1. This kit is a compact, efficient solution for various robotics applications, providing flexibility and adaptability for your mechanical projects.

Ideal for hobbyists and engineers alike, this gearbox can be used to power small robots or mechanical models. With its adjustable gear ratios, it allows for precise control over speed and torque, making it suitable for tasks requiring different levels of power and efficiency. Whether building a slow-moving tank or a fast, agile robot, this gearbox can be tailored to meet your needs.

The gearbox is available in two color options: a solid gray version packaged in a box and a clear variant packaged in a plastic bag. Both versions maintain the same high quality and performance, allowing you to choose based on aesthetic preference or packaging needs.

Equipped with 3 mm hexagonal axles that extend 10 cm from tip to tip, the gearbox is compatible with a wide range of Tamiya wheels. This compatibility offers numerous possibilities for customizing the speed and maneuverability of your robot. The included low-voltage motors operate on 3-6 volts, making them an excellent match for the DRV8833 motor driver carrier. To prevent motor overheating, it's advisable to use stall-detection sensors or monitor your robot to avoid prolonged stalling.

For those seeking to enhance performance, the motor in this kit can be swapped for a lower-current, higher-voltage motor. This modification allows for compatibility with controllers like the qik 2s9v1 dual serial motor controller, TB6612FNG dual motor driver carrier, or Baby Orangutan B-328 robot controller, expanding the kit's versatility and application range.

Note: This gearbox is a kit that requires assembly. To integrate it into your robotics projects, you'll need to connect the motors to your own robot controller. This hands-on assembly process provides a rewarding experience for those looking to deepen their understanding of mechanical systems.
