TAMIYA twin-motor gearbox
Price:
$12 USD
This is a very nice little package. You have to assamble yourself, and there are 3 ways.
You want to assamble in "C"-mode, ratio 203:1
The A & B setups, 58:1 are really fun because they are fast etc.. until you try to make your robot use it. It is simply not strong enough for the fast-changing pulses etc from a PIC-controller, it is useless because it takes so much time to accelerate, and many setups will not ever get up to speed at all..
I strongly recomend that you buy some TAMIYA wheels or belt-tracks to accomplish, and also other parts in this series from TAMIYA, the plates, sticks etc.

Here is a robot driviing one of these http://letsmakerobots.com/node/386
I just assembled mine; I
I just assembled mine; I also opted for the C configuration. Next step is the wheels and the belt tracks. Then I need to find a plate or something to mount it on, but that shouldn't be hard. Thanks for posting the picture, so I don't have to take any. Did you take the picture? What are the red/white/blue wires on the left side for?
My guess is that those wires
My guess is that those wires are for encoders (I think you can see some circuit boards in the center).

Oops - I stole the picture
Oops - I stole the picture from somewhere on a google-search. Illegal and all.. And now I am getting for it, the picture has extras on it!! :D Well then, there you go, you can also add encoders.. aparently!

Yeah I thought so... those
Yeah I thought so... those solder joints where much too clean to be made by you :-D
You can see the encoders here:

A little tip:The two
A little tip:
The two gearboxes are mirrored, so in order to make the wheels turn the same direction, the motors must turn in opposite directions. Took some debugging and tracing wires, before I got it right :)
Any one knows of any
Any one knows of any replacement motors than the stock ones? These motors are designed for low voltage (1.5 to 3v). I would like the motor voltage about 5v to 7v range. Does a motor from GMn serires from Solarbotics fit the Tamiya gear box?
Thanks,
