Pololu Tamiya 70168 Double Gearbox Kit

The Tamiya double gearbox is a versatile and compact unit featuring two independent motors and gear trains. This kit provides all necessary components to configure any of four gear ratios: 12.7:1, 38:1, 115:1, and 344:1. Each side can be assembled with different gear ratios, offering flexibility in design. The gearbox allows for two possible output axle locations, depending on the chosen gear ratio.

Ideal for robotics enthusiasts and hobbyists, this gearbox kit offers the ability to experiment with different speed and torque combinations. Whether building a small robot or a more complex machine, the ability to customize gear ratios enables precise control over movement and performance. Its compact design makes it suitable for projects with limited space, while the independent motors offer enhanced maneuverability.

One of the standout features of this gearbox is its compatibility with a range of complementary products. The included 3 mm hexagonal axles, measuring 10 cm in length, are compatible with various Tamiya wheels, providing multiple options for adjusting robot speed. The low-voltage motors operate on 3-6 volts, making them a great match for motor driver carriers like the DRV8833. For those looking to use higher-voltage controllers, the motors can be replaced with alternatives that suit specific project needs.

Compared to the Tamiya twin-motor gearbox, this double gearbox offers a more compact and robust design. Its shorter and wider dimensions, along with smaller and broader gears, enhance durability without compromising functionality. This makes it a reliable choice for projects that demand a sturdy and adaptable gearbox solution.

Note: Assembly is required for this kit, and users will need to connect the motors to their own robot controllers for operation. This offers a hands-on experience, allowing users to engage deeply with the mechanics of their projects.
