Thank you. I will get a try!

Hi: I want to control the ackermann_vehicle in gazebo. I have the car.sdf with "libackermann_plugin.so", but the fiel libackermann_plugin.so did not exist in my gazebo plugin. I have download the source file of ackermann plugin but it can not be built because some dependence is not available in ROS Indigo anymore. My ubuntu is 14.04. Could anyone provide the libackermann_plugin or tell me how to get it?

yes. I forgot pointing out the hardware razor_imu_9dof in the first question. I will delete the first one @gvdhoorn

Hello: We used razor_imu_9dof. According to the wiki, the results of the magnetometer calibration in the processing console are only extended model parameters like below,so how can I get the standard calibration parameters?

In the Razor_AHRS.ino, under 'SENSOR CALIBRATION' find the section that reads 'Magnetometer (extended calibration)' Replace the existing 3 lines with these:

#define CALIBRATION__MAGN_USE_EXTENDED true
const float magn_ellipsoid_center[3] = {-91.3749, -45.3609, 97.3201};
const float magn_ellipsoid_transform[3][3] = {{0.985111, 0.0301747, 0.0306485}, {0.0301747, 0.938716, -0.0562648}, {0.0306485, -0.0562648, 0.675503}};

Hello: I calibrate the magnetometer according to the wiki step by step. But the calibration results in the processing console are only extended calibration parameters like below. So where is the standard calibration?
