The idea was to make a labyrinth with white, black and blue coloured walls. Coloured walls help our robot to find its way out of the labyrinth saying it to which side it should turn.&lt;/span&gt;

 <title>Rebel, first attempt at building a robot.</title>
 <link>http://letsmakerobots.com/node/613</link>
 <description>&lt;div class=&quot;field field-type-image field-field-primary-image&quot;&gt;
  &lt;h3 class=&quot;field-label&quot;&gt;Primary image&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
      &lt;div class=&quot;field-item&quot;&gt;&lt;a href=&quot;/node/613&quot;&gt;&lt;img src=&quot;http://letsmakerobots.com/files/imagecache/robot_thumb/files/field_primary_image/rebel_0.jpg&quot; alt=&quot;rebel.jpg&quot; title=&quot;&quot;  /&gt;&lt;/a&gt;&lt;/div&gt;

  &lt;h3 class=&quot;field-label&quot;&gt;What does it do?&lt;/h3&gt;
  &lt;div class=&quot;field-items&quot;&gt;
      &lt;div class=&quot;field-item&quot;&gt;Line following, Driving around free with obstacle avoidance&lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;p&gt;This is a first attempt at building a robot. For now it is able to follow a line, and to drive around free with obstacle avoidance. In the near future I will program it to follow someone/thing, and in the far future I will try to let it solve a maze. ie. find it&#039;s predefined goal in a maze. The programming bit wasn&#039;t the hardest for me as I am studying Computer Science. It was the electronics that I really had to dive into. But in the end that was also not the hardest. I really enjoyed building my first robot and I think many will follow. &lt;/p&gt;
