I added this to _get_os_info ()

$regex_robot =
'/(archiver|spider|crawler|robot|googlebot|infoseek|scooter|slurp|scout|ultraseek|gulliver|bjaaland|whereEverythingis|linkguard|zyBorg|Jack|netmechanic)/i';

// look for robots

if(preg_match($regex_robot,$this->_browser_info['ua'])) {
$this->_set_browser('os','robot');
$this->_set_browser('platform','robot');
}
// look for Windows Box
elseif...(etc)

Bit of hack and maybe it should be in phpSniff.class.php as
$this->_robots, but it serves my purposes... :-)
