Hello, I am trying to run the Magni on Ubuntu 16.04 and Gazebo 7. I have followed the directions outlined here: [Running Magni in Simulation - Magni Documentation](https://learn.ubiquityrobotics.com/simulation) and am able to spawn the Magni in an empty world. However when I attempt to run a demo and input the command `roslaunch magni_demos simple_navigation.launch` I get the following error:

How can I fix this and launch the navigation demo?

So this is an interesting one, because the robot side code tries to run raspicam, but that fails when in simulation.

The easy workaround is to put raspicam\_node in your catkin\_ws, it has a special compile mode to create a fake executable on x86 platforms. That way roslaunch will still be able to launch it, even though it isn’t needed. Note that the fake node will die immediately, causing an error print in the roslaunch log, but it shouldn’t cause an issue.

Can you open an issue on magni\_robot so that we its logged as an issue that needs a more thorough solution in the future?

Thanks

@rohbotics

Thanks for the quick response on this. I downloaded the raspicam\_node into my catkin\_ws from here: [GitHub - UbiquityRobotics/raspicam\_node: ROS node for camera module of Raspberry Pi](https://github.com/UbiquityRobotics/raspicam_node). However I am getting a new error when I run the command 'roslaunch raspicam\_node camerav2\_1280x960\_10fps.launch.

Yes that is expected if you try to directly launch raspicam, but aruco\_detect should keep running even if raspicam dies.
