			<content:encoded><![CDATA[<p>Os testes que fizemos revelaram que uma bateria apenas para usar no protótipo era insuficiente. A bateria que estamos a utilizar é de 7.2v, usada para alimentar os motores, directamente, e regulada para 5v para alimentar o Arduino.</p>
<p>A situação crítica é a seguinte: quando queremos activar os motores e a bateria está com 6v, o Arduino tem falta de energia e reinicia infinitamente. Teremos então de ultrapassar esta situação separando a alimentação do Arduino e servos da dos motores (que são os que gastam mais).</p>
<p>Para a demonstração iremos provavelmente utilizar uma fonte de alimentação externa, que substitui uma segunda Bateria, de maior capacidade para alimentar o Arduino e os Servos.</p>

</div>
<ul>
<li> Kit Pan e Tilt &#8211; para direccionar o jacto de água</li>
<li> 4 Motores 7.2v (175rpm; 7,1 Kg/cm³ torque)</li>
<li> 4 Suportes para os motores</li>
<li> 4 Rodas “Off Road” &#8211; para andar em terreno irregular</li>
<li> Adaptadores dos motores para as rodas</li>
</ul>
<p>O material chegou todo bem acondicionado, como podem ver pelas <a href="http://picasaweb.google.com/ricdays/ProtoVCI02?feat=embedwebsite">primeiras fotos</a>.</p>
<p>As rodas surpreenderam-nos. Aderem muito bem ao chão, o que nos dificultou o sistema de direcção do carro, pois queríamos usar o sistema parecido ao das lagartas, em que para virar, os motores da esquerda andam para a frente e os da direita para trás (ou vice-versa), fazendo o protótipo rodar sobre si mesmo.</p>
<p>Como as rodas aderem tão bem ao chão, isto tornou-se impossível, porque não deslizam. Estamos a estudar um novo sistema de direcção, mais parecido ao de um carro real.</p>
<p>Agora estamos apenas à espera dos LEDs e da bomba de água. Esta semana vamos começar a montar toda a electrónica por cima da base.</p>
