• --debug: Wait for the vscode client for debug purposes.

rayasdk run

kill

Kill all Ra-Ya apps that are executed by the user rayadevel.

Usage:

rayasdk kill [-h]

Optional arguments:

• h --help: Show this help message and exit

Example

rayasdk run

Notes

• The credentials if you want to connect over ssh to the robot using the rayadevel user are USER: rayadevel Password: gary Port:2222
• The app is deleted when the container is closed, the route for the apps that are being runned is /opt/raya_os/rayadevel/apps/{APP_ID}
• In the simulator the .ur/simulator/apps folder gets mounted, if this folder is deleted the container will not use it, so if you try to run an app it is going to fail, close the container, run any command in the sdk and run the bringup again
• In your home folder there is going to be a folder called .ur that contains two files and a file that saves the current robot that is going to be used in the run option and a folder with the simulator and the apps that are used in the simulation.
