Garbled Odometry Values?

[adnaksAIB]

I output the values from the left and right encoders (line 1360 of OpenInterface.cpp).

The values appear to fluctuate between 0 and 600 even when the iRobot Create 2 is stationary.

When I move the robot, the range of values does not seem to change much.

Also, the left and the right encoders output very different values even when the robot is moving in a straight line.

Has anybody experienced this type of issue before? Is there some parameter/setting that I'm missing?

Thanks.

I encounter that the /odom values is changing even the create2 is not moving

orientation: y and w

I am new to robotics and ROS I am not sure how this /odom topic will affect the results once I implement localization/SLAM.
