Some FYI on this project.

I'm currently waiting on KeyeStudio, the supplier of this RobotTank kit, to come off their Chinese New Years holiday and provide us with the basic "demo" Arduino sketches for this, instead of the Mixly graphical "code" they provide.

There are a few reasons for this. First, I'm personally not into graphical programming (like Mixly, which seem like a child's programming toy to me) and strongly prefer the C++ like Arduino IDE coding. Second, when I downloaded the mixly archive file provided by KeyeStudio, my Avast anti-virus scanner complains the archive contains some malware; and I'm just too busy to debug and "de-virus" the KeyeStudio Mixly archive.

KeyeStudio has kindly informed me they would get me the actual Arduino demo sketches for this robot kit after the Chinese New Years holiday is past, sometimes in February. I was going to make a video on the "virus alert" when unarchiving the mixly archive from KeyeStudio, but I've just been busy and making a "look at this virus alert" video for a supplier has not been a priority here. KeyeStudio was not satisfied with my photos of the virus alert(s) and requested a video!


I imagine, however, I'll start coding this robot long before I get the demo Ardunio sketches from KeyeStudio, but let's see what happens. My plan is to go beyond the kit and add some other sensors plus some other command and control boards. Let's see how long this kit can hold our attention. We have been playing with the kit little by little, not in a hurry, since we are waiting on supplier to get us the Arduino demo sketches before diving too far into this.

More later as we progress......

Note: The spelling is correct. It is KeyeStudio, not KeyStudio.

LWP::RobotUA(3) 					User Contributed Perl Documentation					   LWP::RobotUA(3)

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. SEE ALSO
