I attached a long thin gun to the flange of the robot (tool0) with a fixed type joint called FTsensor_joint. Then I made the tag < provideFeedback> and < disableFixedJointLumping> true so that the plugin could measure the force and torque of FTsensor_joint. However the result is abnormal because the Y-axis value has a big noise than X-axis and Z-axis like this
It seems like a noise of 50HZ, but I'm not quite sure.The problem is why noise of Y-axis(force) is much bigger? And how to eliminate it?
Another strange thing is when I made the tag of joint link_6-tool0 < disableFixedJointLumping> true the noise turned to be very small like this
but Y-axis is still abnormal and has an initial drift. Why??
The platform I am using is ROS-Indigo with Gazebo7. Thanks a lot if you answer my question!
