Every RoboRuckus game needs a game master to set up and run the game. That doesn’t mean the game master can’t also play, since their duties are mostly confined to starting the game and managing things between rounds. This guide assumes you’re using the Raspberry Pi server described in Setting Up the Game. The game supports mobile devices, but for clarity only clicks will be referred to, although taps can be substituted for clicks.
Starting the Game
To begin, connect to your Raspberry Pi via its RoboRuckus Wi-Fi network and start the Kestrel server via SSH (terminal). Turn on all the robots you’ll be using in the game, their LED displays should show the letter “A” when they have successfully connected to the server.
If you’ve installed nginx and dnsmasq, open the set up page in a web browser by going to http://roboruckus.com/Setup, otherwise go to http://192.168.3.1:8082/Setup.
At the setup page, select the number of players and choose a game board to play. The number of players is the maximum number allowed in the game, contingent upon enough robots being available. Optionally, drag between one and four flags onto the board; if no flags are used, a “deathmatch” robot game will be started. You should use vinyl decals, stickers, tape, or something like that to indicate on the physical game board where the flags are. Once you’ve finished setting everything up, click the “Setup” button to start the game; you will automatically be taken to the monitor page.

The Game Monitor
The monitor page displays the current game state, which is useful both for the game master and observers. At the top it shows the maximum number of players allowed in the game, and below that is the game board map marked with all the flags and current positions and orientations of all the robots in the game. The game board map is useful if a robot accidentally wanders off course on the real game board, you can see where it should be and pick it up and place it on the correct space.
Next to the board (or below, depending on the screen size) is a list of the current players in the game and their statuses: The player number, their current damage, their current number of flags touched, and their lives remaining. Next to (or below) that is an indicator showing the current player move or board element being executed.
At the bottom of the page are three buttons. First, if the “Timer Enabled/Disabled” toggle is enabled, the thirty-second player timer, for the last player picking their program, will be used; this will only work if there is more than one player in the game and can be toggled anytime as long as two ore more players are programming their robots. Clicking “Restart Game” will restart the current game, with the current players sent back to the Player Setup page. Clicking “Reset Program” will return the game to the initial state, kicking the current players out and allowing the game master to set up the game from scratch with new (or the same) players.
Clicking on any player number (the yellow squares) will pop-up a window that will allow you modify that player. You can change their robot’s location, damage, number of flags touched, lives, or even switch them to a different robot altogether. This feature is still in testing, and there is no input validation (you could move the bots to a location off the board, for instance), and if you increase a bot’s damage to the the point where additional cards would be locked, the game server will crash. You can only modify a player in-between rounds, not during.
When a robot, or robots, are destroyed in the game the monitor page will show them in the Player Moves section after the end of the round. Below each robot is the zero-ordered [x, y] coordinate of the last checkpoint (wrench or flag) the robot touched, or the starting coordinate of the robot. The round will be paused and no new cards will be dealt until all the bots are re-entered.
The checkpoint is a suggestion that you, as the game master, can choose to ignore as you drag-and-drop the dead robots back onto the board. After dropping a robot onto the board, clicking it will rotate its orientation.
When a robot is destroyed during a round, it should immediately be picked up and removed from the physical board until it’s re-entered at the end of the round, and then placed on the appropriate space.

Submitting the bots for re-entry.
Once you’ve re-entered all the robots and set their orientations according to the RoboRally rules, click “Re-enter Bots” to submit the new bot positions and start the next round. After a robot is killed three times the player is out of the game, and they won’t be available for re-entry.
If you or a player gets lost or hits the back button in the browser and can’t find the correct interface page, don’t worry, you can manually get to any page if you know the player number. Use the following guide to direct the players to the appropriate pages when needed, substituting # for the player’s number (1, 2, 3, etc…). Here, http://roboruckus.com refers to the game server’s address.
- http://roboruckus.com/Setup/ – The setup page for the game master, redirects to the monitor address if the game is already set up.
- http://roboruckus.com/Setup/Monitor – The monitor page shows the current status of all the players and robots in the game, also allows the game master to re-enter destroyed robots into the game.
- http://roboruckus.com/Player/playerSetup/# – The player set up page, which allows a player to pick a robot and enter the game.
- http://roboruckus.com/Player/Index/# – The main player interface page, where a player can enter their programs to control their robot.
Visiting these pages out of order, like going to a player’s interface page before that player is set up, is potentially unsafe and could cause the server to lock-up, so be careful when manually visiting specific pages.
