RoboRugby 2015 - Table Layout

Basic Table Layout

RoboRugby table picture

The layout of the competition table for 2015 is shown in the picture above and in the diagram below.  Printer-friendly pdf versions of the diagram are available in simple form or with dimensions.  There is also a larger version of the diagram, as an image, that you can modify for reports.

Table Details

The competition matches will alternate between two tables.  The tables are made of wood, which is a natural material.  Therefore, surfaces may not be precisely flat, and dimensions are not precise.  Also, the two tables may differ slightly in exact measurements, shape and texture.  The external lighting of the tables in the competition will differ from that in the laboratory.

The playing area is nominally 2.4 m long and 1.185 m wide.  All measurements given are approximate.  The only official measurements are those of the actual tables.

  • All dimensions on the diagram are in mm.  Small dimensions are rounded to 1 mm, large dimensions may be rounded to 5 mm.

  • The wall height is nominally 93 mm, and will not exceed 96 mm.  The wall thickness will not exceed 20 mm.

  • There will be no obstructions within 50 mm of the outside face of each side wall, but this does not apply to the end walls, where beacons and other equipment may be mounted.

  • There will be no obstructions within 700 mm vertically above the playing surface of the table.  The lighting units used in the competition will be at least 800 mm above the playing surface of the table.

  • The table surface will be mostly matt black, but will be grey in part of the scoring area.  There will also be white lines on the table surface, made using glossy white tape approximately 19 mm wide.

  • The scoring areas will be bounded by white bumps, 4 mm high, with a rounded profile.

  • There may be pencil lines on the table, and any such lines should be ignored.

  • There will be 15 balls on the table at the start of each match, in fixed positions as shown on the diagram: 10 white, 4 yellow and 1 red.  The ball diameter is approximately 42 mm.  The balls have loose pieces inside them, to damp their rolling movement on the table.  The mass of a ball is approximately 7 g.

  • Where white or yellow balls will be placed, there will be circular ball holders, approximately 18 mm in diameter and no more than 2 mm high.  These will be coloured to match the table or line on which they are positioned.

  • There will also be one grey cube on the table, approximately 60 mm in each dimension, and up to 35 g in mass.  The red ball will be positioned on top of this cube at the start of a match.  There may be a shallow depression in one side of the cube, to assist in locating the red ball.

  • Infra-red beacons will be mounted at the ends of the table, aligned with the centre-line of the table.  The transmitting position is approximately 90 mm outside the inner surface of the end wall of the table, and about 160 mm above the table surface.  A shield is fitted just below the beacon LEDs, and extends about 85 mm in front of them and about 150 mm in width.  This shield does not overhang the playing surface, but it does extend over the end wall of the table.

  • The approximate robot starting areas are shown on the diagram.  The constraints are given in rule 15.
