The Tamiya single gearbox is essentially half of the Tamiya 70168
double gearbox. The kit can be built with gear ratios of 12.7:1, 38:1,
115:1, and 344:1. There are two possible output axle locations (for
any given gear ratio, only one output location is possible).
The output shafts are 3 mm hexagonal axles that are 10 cm (about four
inches) from tip to tip. The axles work with any of the Tamiya wheels,
giving you many options for your robot speed.
The low-voltage motors run on 3-6 volts and draw up to a few amps,
making them perfect candidates for the DRV8833 motor driver carrier.
Motor overheating can be caused by excessive stalling, even at very
low voltages. We recommend that you use stall-detection sensors, or
just watch your robot, to make sure that it doesn't stall for more
than a few seconds at a time. For motor specs, see the Mabuchi motor
FA-130 data sheet.
Note: The universal gearbox kit is a kit; assembly is required. To use
the kit in robotics projects, you need to connect the motors to your
own robot controller.
