No `simulator.launch` launch file! #14

Closed Micrified closed 4 years ago

Micrified commented 4 years ago

Having followed the installation guide, I encountered two issues in the First Time Setup sections of the Wiki:

  1. Manually transferring course files to the gazebo workspace does not seem to work. That is because the instruction asks we run cp -r autosim_ws/src/simulator/world/race_track .gazebo/models/, and the hidden directory .gazebo does not in fact exist. I created it nonetheless and copied the files there.

  2. Launching with roslaunch fails because the launch file doesn't actually exist (roslaunch f1tenth-sim simulator.launch run_gazebo:=true). I used find to try and locate the launch file (should it be misplaced) but no results were found for simulator.launch.

The wiki has been updated. Replace simulator.launch with simulator.access in the launch command. The argument run_gazebo is no longer necessary with the current release.

@varundevsukhil Thanks for your answer! I really appreciate the outstanding response time! Unfortunately this does not work either. Here is the directory layout of src you get after performing the cloning and installation steps:

It seems the package name is simulator, and the the contents of launch are:

  1. racecar.access
  2. simulator.master

However attempting to use racecar.access fails too.

varundevsukhil commented 4 years ago

The package name is f1tenth-sim not simulator (this is just the folder name). The contents of the launch directory are accurate. Try the following in sequence:

  1. roslaunch f1tenth-sim simulator.master
  2. roslaunch f1tenth-sim racecar.access

If it does not work, post the terminal output here (entire terminal from launch command to the last printed line)

@varundevsukhil The first command works correctly. Thank you so much for resolving my issue!

In summary: The launch file has a typo in Wikipedia. I used the correct name in testing, but changed the package name to simulator in error (believing this was the correct package name). Now both are correct!

Much appreciated! :)
