Warning: TF_REPEATED_DATA ignoring data with redundant timestamp for frame odom at time 176.254000 according to authority unknown_publisher
Hi all, I am trying to generate the map using
rosrun gmapping slam_gmapping scan:=scan _odom_frame:=odom for my 4wheel_bot environment. This is the github link of my repo for your reference and you can find the frames.pdf file also. I am having two issues when i run the launch file.
I keep getting this error after i run the launch file and also when i run this command
rosrun gmapping slam_gmapping scan:=scan _odom_frame:=odomWarning: TF_REPEATED_DATA ignoring data with redundant timestamp for frame odom at time 176.254000 according to authority unknown_publisher at line 278 in /tmp/binarydeb/ros-noetic-tf2-0.7.6/src/buffer_core.cpp
the map in the rviz is moving when i make the bot move to generae the map even if i changed the fixed frame to "/map" frame from "odom" frame. It has to stay still right? and i can see the difference of bot moving in gazebo and rviz differs. for example lets say if the bot moves 2m in gazebo, in rviz the bot moves quiet slow. you can see here
the rosnode list are
/controller_spawner
/gazebo
/gazebo_gui
/robot_state_publisher
/rosout
/rviz
/slam_gmapping
/teleop_twist_keyboard
Would be glad if anyone point out what did i do wrong. Thanks in Advance
Please edit your description and show us the output of
rosnode list.I updated the question with rosnode list. But which description u mean?
Why are you running slam_toolbox? The wiki page says it is a "replacement" for gmapping, which hints to me that you should not run both at the same time.
That's my fault, I forgot to delete the slam_toolbox node in the launch file. If i keep the slam_toolbox, the map display in rviz shows warning "no map received". That's why i go forr gmapping.
