Correcting for motor Slop

[JasonC1017]

Has anyone figured out how to overcome the gear slop with the NXT motors (either in software or with gearing)?  I am trying to get the motors to go back to a very specific location, but due to the gear slop, I am getting large inaccuracy in the position where it stops.

Thanks,

Jason

Here is a previous discussion forum that discusses how to implment precision motor control using NXT commands. Do any of the suggestions listed here seem like an option for your application?

Thanks for the reply.  Not sure if the solution is applicable as I am only using one motor.  Basically, I have the motor record its start position, do a motion, and then I want it to come back to that position.  The encoder reads that it is back to the original position, but the physical piece connected to the motor is off a few degrees.  This seems to be due to the gear slop in the NXT motor (can move the motor connection mount slightly without actually moving the motor gear system itself).  Did this help clarify?

Thanks,

Jason
