Registering for an LRT Event

Teams need to be registered for the correct Live Remote Tournament before they can connect . To find events, visit and search by program and event type “Live Remote Tournament.” Teams can attend LRT events outside of their geographic region, however some events may be restricted to only teams from that region. The event’s information page should state if any such restrictions are in place.

Logging into LRT

On the day of the event, the Primary or Secondary Contact on for the registered team needs to be logged into their account via the Google Chrome web browser on the same computer the team will be using for audio and video for the Live Remote Tournament.

Once logged in to, the coach should go to and select the team from the dropdown menu. If you accidently select the incorrect team, click on the gear icon on the top right-hand side of the screen and select “Change Teams.”


All teams in a coach’s account should appear in a drop-down list. Only one team can be selected per computer.

Connecting Audio, Video, and Robot Controllers

When you log into, you will be asked to connect the webcam (making sure your field fits in the purple outline), select your audio input, and connect your controllers via micro-USB as detailed below the next image. You will also be asked to select your autonomous programs via the V5 controllers in order to successfully connect the controllers to the LRT system. The setup window will also identify whether you are using V5 robot brains with a supported firmware version.


The LRT setup window is shown above. You must select these settings each time you log in to

Order of Operations for Connecting Controllers

  1. Go to and log in as the team that is competing.
  2. Power on the V5 Brain and Controller for each robot.
  3. Ensure each V5 controller is paired to its respective robot via the V5 Robot Radio.
  4. Select the program you wish to use on the V5 Controller and select ‘Run’ on the controller.
  5. Connect each V5 controller to the computer using two micro-USB cables.
  6. Select ‘Connect Controller’ in the LRT platform for the first controller.
  7. Google Chrome may require you to select the VCOM# from a list to connect your controller to a serial port as show in the image below. Simply select the controller and click ‘Connect.’
  8. Repeat steps 6 and 7 for the second robot.
  9. Once both controllers are paired, and your audio and video settings are configured, click ‘My Field Is Ready’ to continue.


View of the controller connection process. A Google Chrome popup may appear asking the user to select a controller to connect to a serial port. To continue, select the controller from the list and click ‘Connect.’

Joining the Practice Lobby

Once you click ‘My Field is Ready’ in the setup window, you will be taken to the practice lobby. In the practice lobby, you can access the solo practice mode and create practice matches. Solo practice mode allows teams to test the functionality of their autonomous routines within the LRT platform, and verify their camera is working properly. Practice matches can also be created, and other teams who are currently in the practice lobby will have the option to join the match.

The image below shows the LRT Practice Lobby. The list on the left-hand side of the screen identifies teams that are currently in the practice lobby, as well as the practice matches which are currently active. In the middle of the screen are options to create a practice match or enter the solo practice area.


Solo Practice Mode

Teams should test their computer setup ahead of the event, including webcam, microphone, and speakers. Testing in advance gives teams time to troubleshoot issues before competing.

It is highly recommended that teams utilize the solo practice system on to test their robot’s controller connectivity, autonomous function, and camera setup. Solo practice allows a team to test Driver and Autonomous modes as well as view their webcam. Remember that often what a webcam will see in terms of visibility and brightness may not match what your eyes see, so use the webcam view in Solo Practice to adjust lighting or viewing angles as needed.

Note: Your camera view will appear in a real LRT exactly as it does in solo practice mode. Additionally, the autonomous and driver buttons in solo practice mode function the same in a real LRT. If your team is having issues running an autonomous program in solo practice mode, the autonomous program will likely not work in a real LRT. As such, teams should use this mode to ensure their robot and camera setup is fully functional within the LRT platform BEFORE attending their event.


These screenshots include the button for the “Solo Practice” feature in the remote practice system, as well as the panel for testing different robot modes. Your webcam feed will also be shown on screen to assist you in checking your camera settings.

If you are not able to view your webcam or get your computer to work in solo practice mode on please contact or your Team Engagement Manager for assistance.

It is recommended that teams set up a large TV/monitor, if available, to be able to duplicate their monitors to be able to view other teams’ fields better. Teams may also consider using an external set of speakers pointed at the driver’s station so teams can clearly hear the audio stream.

Joining the Tournament

Once the Tournament Operator has started the event, you will see a “Go to Event" pop up on the bottom of the LRT practice lobby screen, as shown below. Clicking will allow you to join the event.


Once you join the event, you will be automatically brought into the LRT Main Lobby, which displays the match list on the left-hand side of the screen as shown below. Your team number will be highlighted in yellow for all upcoming matches. Teams can communicate with other teams and event staff via both the public Event Chat on the right-hand side of the screen and private chat by clicking on the icon in the upper right-hand side and selecting who they wish to chat with. You will remain in the lobby until the Tournament Operator starts a match that includes your team.


Each of the items numbered in the image above is described as follows:

  1. Match Schedule, Rankings, and Alliances tabs. Clicking between these three tabs allows you to look at the match schedule, the current rankings, and the alliances for elimination matches, once they have been generated. The rankings will automatically update after each qualification match.
  2. Current Match. This section shows the match that is currently being played.
  3. Upcoming Matches. This section shows the remaining matches to be played. You can click the ‘Queue’ button next to your upcoming match to actively queue for that match. Clicking that button will bring you into the Match Lobby for that match. Note: If a team does not actively queue for their upcoming match, the EP can automatically bring the team into their match.
  4. Completed Matches. This section shows matches whose scores have been finalized.
  5. Livestream. In the center of the screen is the livestream. All Live Remote Tournaments are livestreamed on the REC Foundation’s YouTube channel. The generated livestream is unlisted, meaning it will not show up on YouTube search results. However, any person with the link to the livestream can watch the event live. Click the YouTube icon in the bottom right corner of the stream to find the shareable link.
  6. Event Chat. Teams and volunteers can post in the event chat. Posts in the event chat will appear for all users in the tournament.
  7. Communication Options. In the top right corner of the Main Lobby are the communications icons. From left to right, the icons are Mute/Unmute, Private Chat, and Settings. Mute/Unmute will control the team’s microphone (note: When you are in the main lobby, no one can hear your audio). Private chat allows the user to communicate privately with other teams or volunteers. The settings allow toggle between light and dark mode and allow the user to log out.
