Topic: good motors/gear box for use with tamiya tank (Read 459 times) previous topic - next topic

ive decided to try and build a tank robot with my arduino UNO. after some research ive discovered that the tamiya twin motor gear box's motors are weird in the fact that they have a low voltage and high amps. so my question is what motors/gear box can i use with a basic motor shield like this one: https://www.adafruit.com/products/81 or this one: https://www.sparkfun.com/products/9815

i was trying to save a few bucks, but would it be better/ simpler to just buy the more expensive and correct shield?: http://www.robotshop.com/pololu-low-voltage-serial-controller-2.html

Chagrin

Your motors have a 2.1A stall (peak, when stopped) current. The only driver you have linked that can handle that is the Pololu one.

Be aware that the Pololu controller has a serial interface and will make your programming a bit more complex; read through the specs fully so you know what you're getting into. You might want to look for a motor driver that takes PWM input for the simplicity in programming.
