Wheels and motors

Hi all I have been trying to gear my motors down which is a real pain so I was thinking of buying a Tamiya 70097 Twin-Motor Gearbox. Does anyone recommend this or a different type. I wanna keep costs down so something nice and cheap that has 2 geared independent motors. Also I didn’t think it would be that hard to find wheels. Anyone recommend anything or anywhere?<o:p></o:p>Cheers<o:p></o:p>Vinny<o:p></o:p>

Hi Vinny,It’s easy to find

Hi Vinny,

It’s easy to find motors and wheels if you know where to look. :wink:

Check out www.FingerTechRobotics.com. I run that store and carry geared motors, wheels, and wheel hubs designed specifically for hobby robotics.

Also, you have two identical posts: “wheels and motors” and “motors and wheels”. I recommend keeping it to just one post to keep all the answers in one place.

I have the Tamiya

Yes, I have the dual gearbox. Plastic gears make alot of noise, but the thing runs fine.

The motors are 3V motors, and draw a higher current. You can buy replacement motors that run on 6V at lower current. I bought my replacements from Pololu. http://www.pololu.com/catalog/product/604

As for the wheels, I bought the Tamiya Off-Road tires and the narrow tires, both from Pololu.

This setup works great to quickly throw together a moving platform, just don’t expect it to move quickly or move much weight.

or solarbotics

Solarbotics has many different gear motors, that are worth a look.

But the Tamyia Twin is a popular choice, and I havent heard any complaints about it, so I guess it’s OK.

Cheap way
I have been converting cheap servo motors into continous DC motor. Just remove the stop cog on the main gear and file down the pot shaft or remove it and solder 2 wires to the motor direst. Don’t forget to cut the fiol connections to the motor and add a .1 mfd ceramic capacitor across the motor. They go faster too.
