Re: Mechanical Wheel Encoders?

Hi,
At Team 1425, we used mechanical encoders like the kind you suggested, except with a hex bolt and a limit switch. The problem we ran into is that when it went fast enough, the limit switch would bounce, and not give dead accurate readings. An optical sensor (I saw a few clever ones with Banner sensors) using a striped wheel is much more effective.

I love to take things apart. The fact that they work better when I put them back together it just a bonus.
