5. Robot imu calibration

5、Robot calibration

5.1、Imu Calibration

5.1.1、Calibration steps

Note: When calibrating, make sure the robot is still

1）、Run

cd ~/driver_ws/src/yahboom_bringup/launch
roslaunch calibrate_imu.launch

As shown in the figure below, press Enter to calibrate the data in the X+, X-, Y+, Y-, Z+, Z- directions in turn. After the calibration, it will be automatically saved to the specified folder.

image-20220513164431987

After running, the program will exit with an error, which is normal.

Calibration data is stored in,

xxxxxxxxxx
~/driver_ws/src/yahboomcar_bringup/param/imu_calib.yaml
