(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.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.Set angular x value between 0.1-0.6. Leave the other values as 0.0.
- 3.Measure how much the robot turns. And similarly, record the time it took to turn.
- 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.Last modified 6mo ago
