  33 <p>This evening I made my first Perl GUI application.  The last few
  34 days I have worked on a Perl module for controlling my recently
  35 aquired Spykee robots, and the module is now getting complete enought
  36 that it is possible to use it to control the robot driving at least.
  37 It was now time to figure out how to use it to create some GUI to
  38 allow me to drive the robot around.  I picked PerlQt as I have had
  39 positive experiences with the Qt API before, and spent a few minutes
  40 browsing the web for examples.  Using Qt Designer seemed like a short
  41 cut, so I ended up writing the perl GUI using Qt Designer and
  42 compiling it into a perl program using the puic program from
  43 libqt-perl.  Nothing fancy yet, but it got buttons to connect and
  44 drive around.</p>
  45
  46 <p>The perl module I have written provide a object oriented API for
  47 controlling the robot.  Here is an small example on how to use it:</p>
  48
  49 <p><pre>
  50 use Spykee;
  51 Spykee::discover(sub {$robot{$_[0]} = $_[1]});
  52 my $host = (keys %robot)[0];
  53 my $spykee = Spykee->new();
  54 $spykee->contact($host, "admin", "admin");
  55 $spykee->left();
  56 sleep 2;
  57 $spykee->right();
  58 sleep 2;
  59 $spykee->forward();
  60 sleep 2;
  61 $spykee->back();
  62 sleep 2;
  63 $spykee->stop();
  64 </pre></p>
  65
  66 <p>Thanks to the release of the source of the robot firmware, I could
  67 peek into the implementation at the other end to figure out how to
  68 implement the protocol used by the robot.  I've implemented several of
  69 the commands the robot understand, but is still missing the camera
  70 support to make it possible to control the robot from remote.  First I
  71 want to implement support for uploading new firmware and configuring
  72 the wireless network, to make it possible to bootstrap a Spykee robot
  73 without the producers Windows and MacOSX software (I only have Linux,
  74 so I had to ask a friend to come over to get the robot testing
  75 going. :).</p>
  76
  77 <p>Will release the source to the public soon, but need to figure out
  78 where to make it available first.  I will add a link to
  79 <a href="http://wiki.nuug.no/grupper/robot/">the NUUG wiki</a> for
  80 those that want to check back later to find it.</p>
