/odom returns zero velocity

Open ozgudum opened this issue 3 years ago • 2 comments

ISSUE TEMPLATE ver. 0.4.0

  1. Which TurtleBot3 platform do you use?

    Waffle

  2. Which ROS is working with TurtleBot3? ROS 2 Foxy Fitzroy

  3. Which SBC(Single Board Computer) is working on TurtleBot3? Raspberry Pi 3B+

When I'm running TB3, I am always getting near zero values for /odom/twist. Is this expected? I would expect to get robot velocity in m/s. No issue with /odom/pose
