Drill motors

[woody]

Pick a drill with an rpm around the 900-1100 mark.
You can then simply remove the chuck ...attach 100mm wheels in their place and get a speed of around 10 mph.

I want to arm my bot with an electric lifter - but still want it to have enough power and grunt to push around. I will be using 100mm blue wheels.

Thanks for the tip Woody.

With wool worths closing down I got a few bargans.
One was an 18 volt drill for 15 quid. Not for a robot.

does anyone know how fast 12v el cheapo B&Q drill motors overvolted to 14.4v would go with 19cm diameter wheels?

very quick, drop the diameter down to around 10cm mark or throw in some extra gearing. I could see you burning out the motors with a wheel that big or drawing huge currents through your controllers.

Depends how flexible your wheels and drill mounts are. I did get away with large wheels but it was very flexible and had a lot of give.

When in the arena and the wheels got a layer of dust, it was very difficult to drive.
I would also suggest going to around 10cm.
