I'm just making this post to ask a question about how reliable the robot detection is for DeviceAtlas. I'm currently developing another site here in Japan and I was running through a few test UA's one of them being a google-mobile bot and while the test UA is being detected as a phone it's not coming up as a robot.

Here is the test UA. This is an actual google UA that hits my Japanese sites consistently.
DoCoMo/1.0/N505i/c20/TB/W20H10 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html)

And here is a list of the data returned by the PHP API for DeviceAtlas:
Array
(
[isFeedReader] => 0
[isChecker] => 0
[isSpam] => 0
[isBrowser] => 0
[isDownloader] => 0
[isFilter] => 0
[mobileDevice] => 1
[isRobot] => 0
[image.Gif87] => 1
[id] => 208592
[https] => 1
[memoryLimitMarkup] => 20000
[markup.xhtmlMp10] => 1
[image.Jpg] => 1
[usableDisplayWidth] => 240
[usableDisplayHeight] => 202
[jsr139] => 1
[vendor] => DoCoMo
[model] => N505i
[displayWidth] => 240
[displayHeight] => 270
[displayColorDepth] => 18
[_matched] => DoCoMo/1.0/N505
[_unmatched] => i/c20/TB/W20H10 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html)
)

As you can see isRobot is set to 0 while the UA is clearly from Google. Any ideas why this might be happening?
