Well, we guess you already knew that :)</p>

<p>First we’ll talk about <strong><em>Manual Robotics</em></strong>, the ones controlled by human (yup, that’s you) </p>

|

<li>
|
||
<p>Then, we’ll move on to autonomous bots, the ones which can perform simple tasks on their own. ( Remember Wall-E ? ) </p>
|

</li>
|

<li>
|
||
<p>If time permits, we’ll talk about robots with <strong>“eyes”</strong> (err.. cameras).</p>
