Maze arena specifications


Is there any sort of guarantee regarding the construction of the maze field, namely the material of the field, and the color of the field (which is surprisingly not specified in the rule, but obviously presumably white). Is there any dimension specifications of the maze at internationals?


Dear DeLuXe,

We have not specified the material and construction of the arena in the rules intentionally. This is because different material is available in different regions.

And for example at a school or regional competition they may not have the money to build arenas in aluminium or plexiglass. They just need something to form a maze with.

In addition a real rescue robot may not know exact how the building is made, not the materials nor the colors.

We in the TC writes the rules, but it is the local organizers in Japan that manufacture and prepare all material for the OC to run the competition.

Having this said I can tell you from my experience of many international events that they arenas will be made of wood painted white or close to white. The squares in maze should be 30cm, but some organizers count this as a CC measurement and have walls that is 2-3cm so the actual space between two walls is closer to 28cm, according to rule 1.1.3:
“Their width can reduce the available space for doorways and paths”

The height of the walls will most probably be 15cm to make it easier for the audience to see the robots.

Hey Fredrick,

In Germany, the maze contained aluminum pillars to connect the walls together. You state above that “arenas will be made of wood painted white or close to white”. If these pillars or similar connectors are used in Japan will they be white like the walls?

Dear Rory,

I suspect the arenas to be similar to last year.

Pillars may be aluminium. Is that a problem?

Hey Fredrik,

With that knowledge, we will try and code for the pillars. The silver might be problematic with our Binary Filter on the cameras. Worse yet, the aluminum also has an effect on LIDAR’s reading. The returned readings from the LIDARs when it measures the distance from the pillars are usually erratic and unpredictable and will also need to be filtered out.

Nothing that can’t be fixed with code. Just wanted to confirm that they will be used.
