IR Wheel encoder - reliabilty

Javalin

Hello all,

Does anybody have any experience, ideas?, on making an IR wheel encoder work more consistanty.

The encoders & wheel disks are these:· http://active-robots.com/products/motorsandwheels/wheel-encoders.shtml

(the top two products)

When the are setup on each wheel, one returns a fairly consistant set of pulses (0-5V) and the other widely varies.· They are both mounted under the body of the robot, at nearly equal distances and positions relative to the wheels.· Using the CPU.count method on the Javalin to count pin transitions.

Help?

Did you try to exchange either the wheel disks or the encoders. Does - in this case - the other encoder return varying pulses?

Hi Gunther,

Thanks for the idea!

The tech support guy from www.roboticsconnection.com (manufacturers) emailed me as well, turns out the mounting distance 4mm was too far.

Ideal is 1.5 to 3mm appearently.

Cheers

James
