Unknown robot (identified by 'robot')

Does anybody know what this means:
Unknown robot (identified by 'robot')
This was in the stats in my cPanel, Just wanted to make sure it wasn't something I had to worry about.

It's normal, there are many robots that visit sites that Awstats isn't programmed to recognize by name, so it only lists them a "robot". You probably have an IP address and you may be able to find out where it originates.
