Its about time someone took a drill motor/ transmission and adapted it properly for robots. At this point, I am a friggin' expert on drill motors, current draw (the fact that they suck incredible power when stalled) and how to mount sprockets and wheels.

I am drooling over your drill motor combos there --It would have made my life considerably easier on a lot of old projects. --And at 30 quid, you got a great product there. I have been thinking of starting to carry some "big robot" parts... I may just have to get a couple to play with.

Oh, and you guys should consider carrying the Dagu Wild Thumper controller --It would be a perfect match for your motors.

Thanks for the kind words Chris, I expect we came about our experience with drill motors in a similar way, for me it was building countless combat robots (à la http://www.fightingrobots.co.uk/)

We've been able to source components directly from a factory churning out tens of thousands of cordless drills a year for the US market which is how we've managed to keep the price around £30 even after adding all the CNC'd aluminium parts and accessories.

I've just had a look at the controller you mention, unfortunately it seems a bit low current unless the robot were particularly light-weight or low voltage. I usually recommend something like the 2x25 Sabertooth to handle the 550 sized motors (http://www.dimensionengineering.com/products/sabertooth2x25), though recently there's been a very interesting development by some Australian roboteers, modifying brushless controllers for DC, e.g.: http://www.botbitz.com/index.php?route=product/product&path=59&product_id=59 - incredible current handling for the price.
