rviz can not send goal to move_base from another computer [closed]
I am running a car-like robot. I have an move_base node with global/local planner, and I can send goal from rviz to move the car. Now, I want to run the rviz from another computer. Everything works fine, I can see the tf, laser scan etc in rviz. But when I sent the goal with "2D Nav Goal" in rviz from another computer, the car did not move. The car did not get the goal message either when I run "rostopic echo".
Why?
In addition to the suggestions below, make sure the robot can ping your computer by name. If it can't, you need to unset your
ROS_HOSTNAME
and set yourROS_IP
instead.Is this not a duplicate of #q298933?
Indeed it is.
