Arenas used in the 2014 Australian National RoboCup Primary and Secondary Rescue competitions.
I hope these images will be of use to teams preparing for the 2015 RoboCup in Adelaide.
The Rescue competitions are split into three sections, Primary Rescue, Secondary Rescue, and Open Rescue.
Primary and Secondary RoboCup Rescue Arenas
These are some of the arenas used in the Saturday Primary and Secondary events. Robots start from the tile marked with a letter.
This was the first Arena used for the Primary RoboCup Rescue event.
An arena used in the RoboCup Secondary Rescue, the partially hidden tile behind the see-saw is a cattle grid.
I lost count of which of the rest of the arenas were used for Primary and Secondary Rescue, generally the Primary arenas were the less complicated ones.
The finals were run using a monster "three-headed" arena. Each robot had a run on each of the three courses, their scores being combined to find first, second and third.
There were so many people taking a photograph of this remarkable arena, that it was difficult to get a clean photograph. This was the best I could manage. The tiles under the raised tiles can be seen below.
The double curved lines on one tile that can be seen in the right of this photograph, were both in use in different courses. In one of the final runs, two robots on different courses only just managed to avoid a collision at this part of the course! The "legs" supporting the upper tiles are apparently not considered to be part of the hazards, as one robot had minor problems with one leg, and the legs were moved for later runs, as can be seen in the image below.
Open RoboCup Junior Rescue Arenas
For the Open Rescue Robots on Sunday, things got harder.
Open Rescue Robots tend to be big; the orange "gate" checks the size of the Robots.
Some arenas are not much more difficult than the Saturday arenas.
Only the Open Rescue arenas can use the difficult "Gridlock" tile, seen on the left of this image.
Open Robots have more obstacles.
Putting the gridlock on a slope makes the course more difficult.
For the Finals, another huge "three-head" arena was constructed. It is the first time I have seen a double gridlock being used.
This is the view from the other side of the triple-course areas. Again, the robots competed at the same time to rank the top robots into an order of merit.
Just before the finals, this caused some consternation! Thankfully, the see-saw on the slope was removed before the finals.
After the finals, the see-saw was replaced to see if any robots could climb it. All failed to get over (wmv video). That may have been because all were two-wheel drive robots. This is similar to the problem faced by Yaya Lu in 2009 when she entered (and gained a first in) the International RoboCup Junior Rescue event in Graz Austria which included a steep ramp. She had to use an 8-wheel drive (similar to her "sixteenth robot" on web page http://www.yayalu.net/YayaLu2009/YayaLu09.htm) to get up the slope reliably. Perhaps a similar approach might be needed here.
For the record, I have no official connection with RoboCup Australia, official photographs and results can be seen here
