Abstract: Aiming at the serious distortion problem of drill tool azimuth angle calculation caused by the measurement error of the magnetometer while drilling, an ...

While implementing a sensor fusion filter using an accelerometer, gyroscope and magnetometer, I found the mag to be unreliable. This is most likely because of the lack of calibration. So I set out to ...

base_calibration_node - can determine scaling factors for gyro and track width parameters by rotating the robot in place and tracking the actual rotation based on the laser scanner view of a wall.

Researchers routinely measure magnetic fields to better understand a vast array of natural phenomena. Many of these measurements are performed in shielded environments, but the research community has ...
