<h1>Week 17. Mechanical Design - Machine Design </h1>
<p>This week is machine week. It is a group assignment, but given the situation for the Covid-19 we are going to do it distributed. These are the requirements of the Document Assessment. </p>
<p><b>Mechanical Design</b></p>
<ul><li> Design a machine that includes mechanism + actuation + automation. ✔
<li> Build the mechanical parts and operate it manually. ✔
<li> Document the group project. ✔
<li> Document your individual contribution. ✔
</ul>
<p><b>Machine Design</b></p>
<ul><li> Actuate and automate your machine. ✔
<li> Document the group project. ✔
<li> Document your individual contribution. ✔
</ul>
<p>Like every week, my weekly schedule. 😊 </p>

<p style="color:orangered;"> <i>Given the situation of the COVID-19, this year the construction and testing of the machine has been complicated. In this machine the working group is formed by <a href="http://fabacademy.org/2020/labs/leon/students/alvaro-macian/"><b>Alvaro Macian (Cartagena),</b></a> <a href="http://fabacademy.org/2020/labs/leon/students/lola-ojados/"><b>Lola Ojados (Cartagena),</b></a> <a href="http://fabacademy.org/2020/labs/deusto/students/ivan-gonzalez/"><b>Ivan Gonzalez (Bilbao)</b></a> and myself. As we cannot move around Spain, we have decided to manufacture the machine in <b>León</b> and they will help me remotely. </i> 😊</p>
<h1>Group Assignment.</h1>
<p>The <b>Group Assignment page</b> is at the following <a href="http://academany.fabcloud.io/fabacademy/2020/labs/leon/leon-group-assignments/"><b>link.</b></a>There you will find all the information of the machine.</p>
<p>I am going to be in charge of the machine design, manufacturing and assembly.</p>
<h1>Mechanical Design</h1>
<h2>Jake Read Modules</h2>
<p>During the machine choice debate on Thursday, we decided to use <a href="https://gitlab.cba.mit.edu/jakeread/pgd"><b>Jake's modules,</b></a> drawing inspiration from the work done by Pablo Nuñez, Epifanio Lorenzo, Yuichi Tamiya, Apeksha Bochare, Pradnya Shindekar at the Bootcamp in Kerala (India). An image of the videoconference, showing where the documentation is and how the machine will be.</p>
<span class="image main"><img src="images/week17/week17.02.jpg" alt="" /></span>
<p>Thanks to the documentation of my instructor Pablo Nuñez and the Jake Read repository, I begin to design the machine. In this case we are going to create a machine with two X and Y axes, like a plotter, in which the end effector can be something to paint.</p>
<p>Jake's modules are easy to manufacture because you only need three parts of the structure cut with the laser and assembled with small 3D printed parts. In Kerala they designed some legs, so that the module can be supported. In our case, this is the layout of the machine.</p>
<span class="image main"><img src="images/week17/week17.03.jpg" alt="" /></span>
<p>Modify the part of the slider, so that it can be connected to another module. The green piece is Jake's original, the gray is the modified one.</p>
<p><img src="images/week17/week17.04.jpg" width="60%"; max-width="700" /></p>
<p>By making an inventory of the necessary parts in the Fab Lab León, we realize that we do not have the appropriate size bearings or the necessary inserts. We try to buy them, but they don't sell them in León. So it's time to change the plans. I inform the team.</p>
<h2>Nadya Peek modules</h2>
<p>Thank goodness that during the choice of the machine, we had an option B. And they are the use of <a href="http://mtm.cba.mit.edu/machines/science/"><b>Nadya Peek's modules.</b></a> For several years the students of the Fab Academy of the Fab Lab León have used these modules.</p>
<p>For the creation of the X and Y axes to create a plotter, we were inspired by the machine they made at the <a href="http://archive.fabacademy.org/fabacademy2017/fablabfacens/"><b>Fab Lab Facens in 2017.</b></a></p>
<p>Thanks to Nadya Peek's MTM <a href="http://mtm.cba.mit.edu/machines/science/doc/mMTM_Linear_CRD_002.3dm"><b>page,</b></a> you can download the module designs. Also thanks to the documentation of the <a href="http://fab.academany.org/2019/labs/leon/machine/"><b>"Cintya"</b></a> machine made by the Fab Lab León in 2019, I begin to design the different modules.</p>
<p>A module for the X axis, a module for the Y axis with a union connector for both axes.</p>
<span class="image main"><img src="images/week17/week17.05.jpg" alt="" /></span>
<p>As the Y axis a part is in the air, to give it a mobile foothold, I design a <b>marble holder</b> inspired by the educational robot <a href="https://escornabot.com/web/es"><b>"Escornabot".</b></a> Ivan sent me the design of the end effector, a holder to hold a pencil or a marker and I add it to the simulation.</p>
<span class="image main"><img src="images/week17/week17.06.jpg" alt="" /></span>
<p>This is the 3D view of the machine.</p>

<p>Once the simulation was done, I went on to create the exploded view of the machine to cut it in the laser and the support with the marble holder that will be 3D printed. At the bottom of the page you will find the files to download.</p>
