In Unit 2, I created a launch file for running 2 nodes cartographer_node and occupancy_grid_node. But in rviz map shows error. Please help!!
Hello @dhanaprakaashg ,
Could you provide some more details? For instance:
Is the Shell where you executed your launch file showing any error?
Did you select the
/maptopic in RViz to visualize the map (it’s not appearing in the image)
