color sensor aid
« on: March 16, 2007, 08:20:51 AM »
I was doing research for a new robot in the works, and I came across these two videos:

They both have a small black and white disc. As much as I can figure, They are there for the color sensors, but what specifically do they do?

The small black-and-white discs are probably encoders, and they're used for feedback on the motors to determine how far they've turned. Encoders like those are usually used on DC motors for feedback.
