NAME

       robot-playerjoy - console-based client for teleoperation

SYNOPSIS

       robot-playerjoy [options] <host:port> [<host:port>]

DESCRIPTION

       robot-playerjoy	is  a console-based client that provides planar, differential-drive teleoperation of position2d and position3d devices. In
       other words, robot-playerjoy allows you to manually drive your (physical or simulated) robot around. robot-playerjoy uses velocity control,
       and so will only work when the underlying driver supports velocity control (most drivers do).

OPTIONS

       -v     verbose mode. Print the Player device state on stdout.

       -3d    connect to position3d interface (instead of position).

       -c     continuously send commands.

       -n     don't send commands or enable motors (for debugging).

       -k     use keyboard control (instead of joystick device).

       -p     print out speeds on the console.

       -udp   use UDP instead of TCP (deprecated, currently disabled).

       -speed speed
	      maximum linear speed in meter per second (default: 0.5).

       -turnspeed speed
	      maximum angular speed in degrees per second (default: 60).

       -dev device
	      joystick device file the joystick is connected to (default: /dev/js0).

NAME

       LWP::RobotUA - A class for Web Robots

SYNOPSIS

	 require LWP::RobotUA;
	 $ua = new LWP::RobotUA 'my-robot/0.1', 'me@foo.com';
	 $ua->delay(10);  # be very nice, go slowly
	 ...
	 # just use it just like a normal LWP::UserAgent
	 $res = $ua->request($req);

DESCRIPTION

       This class implements a user agent that is suitable for robot applications.  Robots should be nice to the servers they visit.  They should
       consult the /robots.txt file to ensure that they are welcomed and they should not make requests too frequently.

       But, before you consider writing a robot take a look at <URL:http://info.webcrawler.com/mak/projects/robots/robots.html>.

       When you use a LWP::RobotUA as your user agent, then you do not really have to think about these things yourself.  Just send requests as
       you do when you are using a normal LWP::UserAgent and this special agent will make sure you are nice.

METHODS

       The LWP::RobotUA is a sub-class of LWP::UserAgent and implements the same methods. In addition the following methods are provided:

       $ua = LWP::RobotUA->new($agent_name, $from, [$rules])
	   Your robot's name and the mail address of the human responsible for the robot (i.e. you) are required by the constructor.

	   Optionally it allows you to specify the WWW::RobotRules object to use.

       $ua->delay([$minutes])
	   Set the minimum delay between requests to the same server.  The default is 1 minute.

       $ua->use_sleep([$boolean])
	   Get/set a value indicating whether the UA should sleep() if requests arrive too fast (before $ua->delay minutes has passed).  The
	   default is TRUE.  If this value is FALSE then an internal SERVICE_UNAVAILABLE response will be generated.  It will have an Retry-After
	   header that indicates when it is OK to send another request to this server.

       $ua->rules([$rules])
	   Set/get which WWW::RobotRules object to use.

       $ua->no_visits($netloc)
	   Returns the number of documents fetched from this server host. Yes I know, this method should probably have been named num_visits() or
	   something like that. :-(

       $ua->host_wait($netloc)
	   Returns the number of seconds (from now) you must wait before you can make a new request to this host.

       $ua->as_string
	   Returns a string that describes the state of the UA.  Mainly useful for debugging.
