(2/4) Angular Speed Calibration Check

Angular speed calibration check - Test using pub /cmd_vel for accurate result
Check the angular speed for at least 0.1-0.6 rad/s, and check whether the robot rotates correctly. A video recording is encouraged to troubleshoot any issues that may arise.
Likewise, repeat the same method to check angular speed calibration.
  1. 1.
    Run rostopic pub /cmd_vel geometry_msgs/Twist "linear: x: 0.0 y: 0.0 z: 0.0 angular: x: 0.0 y: 0.0 z: 0.0"
  2. 2.
    Set angular x value between 0.1-0.6. Leave the other values as 0.0.
  3. 3.
    Measure how much the robot turns. And similarly, record the time it took to turn.
  4. 4.
    Check that your calculations match the value you set for angular z.
Alternatively, you may use rosrun telelop_twist_keyboard teleop_twist_keyboard.py. Set angular speed between 0.1-0.5. Then repeat Steps 3 - 5 above.
