Pololu Tamiya 70167 Single Gearbox (4-Speed) Kit

The Tamiya 70167 Single Gearbox (4-Speed) Kit offers versatile gear ratios of 12.7:1, 38:1, 115:1, and 344:1, allowing for customization based on your project's needs. This kit includes two potential output axle locations, ensuring flexibility in design and functionality.

Ideal for robotics enthusiasts, this gearbox kit is perfect for projects that require precise speed control and torque. Its compatibility with a variety of Tamiya wheels opens up numerous possibilities for creating custom robots with varying speeds and maneuverability. The inclusion of 3 mm hexagonal axles, measuring 10 cm in length, ensures a secure fit with compatible wheels.

One of the standout features of this gearbox is its low-voltage motor, which operates efficiently on 3-6 volts while drawing minimal current. This makes it a suitable choice for use with motor drivers like the DRV8833 motor driver carrier. However, care should be taken to avoid motor overheating due to excessive stalling, which can be managed by using stall-detection sensors or monitoring the robot's activity.

The flexibility of this kit extends to motor customization. Users can opt to replace the included motor with a lower-current, higher-voltage alternative, allowing seamless integration with controllers such as the qik 2s9v1 dual serial motor controller, TB6612FNG dual motor driver carrier, or Baby Orangutan B-328 robot controller.

As a kit, assembly is required, and users must connect the motors to their own robot controllers. This provides an engaging hands-on experience and the opportunity to tailor the gearbox to specific project requirements.
