Tamiya 70103 universal gearbox has a thin, compact, metal frame,
making it the smallest Tamiya gearbox. The final two gears are metal,
making for a tough output. A worm gear allows for the high gear ratio
options of 101:1, 269:1, and 719:1. The main output shaft can be
oriented in four different directions, and a small, auxiliary output
shaft turns perpendicularly to the main output shaft.
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.
