Faster Motors for BOE-Bot???

Posts: 54
I'm just finishing a line maze bot with BOE-Bot, and I can see it does the maze well.
But in a "fastest time" contest, I'd be in trouble.
Anybody have any experience with faster servos?
Or will I have to replace servos with motors to get more speed?

This servo is .15s for the same
While this servo is .11s. You'd have to modify this one to continuous rotation.

Some servos are definitely faster than others, if you want to check specs and swap them out. But I agree with Franklin that replacing servos with gearmotors will give you the widest range of speed & torque. Pololu and Solarbotics both offer a variety of gearboxes (brass and plastic, each available·in multiple gear ratios) and the Pololu·dual motor controller is small, cheap and works well: http://www.pololu.com/catalog/product/411.·You can use up to 9 volt motor supply voltage. The controller adds "set & forget" speed control so you don't have to send a continuous string of pulsouts to keep your motors moving, so you're free to monitor your sensors and react accordingly.

I also ran into a few fairly easily servos at a local RC-Hobby store, which ran a little faster too, but were a bear to modify to constant rotation. (mechanically, easy, but connecting a 5K Trim-POT to the outside, was tough.. too much signal drift.
they seemed sensitive to RFI.) I bought a pair, with the idea of replacing the stock CR-Servos from Parallax, which were beginning to "Scream" (motor bearings worn. result, massive armature chatter.)..
