For the 2019 Phase 2 - Dress Rehearsal, teams will submit their system so that it can be run against previously-unseen scenarios. Teams have already been exposed to all of the tasks that will be present in the Dress Rehearsal scenarios. A single system must be designed to solve any of the VRX 2019 tasks.

The VRX task description document has all the details about the tasks and about the environmental envelope expected in the unseen competition scenarios.

To ensure that your system can adapt to previously-unseen scenarios, teams should test their system at least against all released sample tasks.

To help you prepare, we've provided Phase 2 Task Practice which includes eighteen example worlds for local testing to prepare for VRX 2019, Phase 2. These example worlds are representative of the task configurations and environmental conditions specified in the task documentation.

For the evaluation of your Phase 2 submissions, the solutions will be run through each of these example worlds, along with some new configurations that are not released prior to the Phase 2 deadline. The objective of this approach is to allow teams to practice with some of the actual scenarios they will see in the Phase 2 competition, so that they can compare their local performance with the results from the phase. We also introduce new, previously-unseen scenarios, to exercise the solutions ability to deal with new configurations and conditions.

We expect to receive three files from each competitor prior to this event:

• dockerhub_image.txt: Contains the name of the image to be pulled from DockerHub. If you're using a private DockerHub repository, please grant access to the virtualrobotx DockerHub user, which will be used by the organization to access your solution. Follow this tutorial for instructions about how to create your own Docker image.
• thruster_config.yaml: Defines the WAM-V thruster configuration.
• sensor_config.yaml: Defines the WAM-V sensor configuration.

See the submission process section in the wiki for instructions about how to submit these files.

Once you submit the pull request, the VRX technical team will do two things before merging (accepting) the submission:

1. Check that the WAM-V thruster and sensor configuration complies with the configuration constraints described in the VRX Technical Guide
2. Check that the DockerHub image is accessible by the virtualrobotx DockerHub user.

Once those two requirements are met, the pull request will be merged and evaluation of the solutions will begin.

Date	Description
2019, October 21, 23:59 PST	Deadline for submitting your solution
2019, October 22, 23:59 PST	Deadline for submitting a correction
2019, October 28	Results published

Note: We'll allocate an extra day in the schedule (October 22) for fixing any problems related with the content of the submission files (e.g.: A noncompliant sensor or thruster configuration, a typo pointing to the DockerHub image, a problem with DockerHub permissions not letting Open Robotics to download your solution image). Teams are not allowed to modify the DockerHub image after the deadline on October 21.

From the VRX Competition and Task Descriptions, “To be eligible for Phase 3, teams must submit their solution for automatic evaluation as described in the VRX Technical Guide”. So as long as a team provides the three files, they will move on to Phase 3.

The submissions will be scored by the technical team and the scores will be made available to the teams, but the dress rehearsal score is not counted toward the final score - it is only for helping the teams get ready for the final.
