<h3><strong>THE IDEA:</strong></h3>
<p>There are at least 4 other projects on Instructables.com (as of May 13, 2015) around modifying or controlling OWI Robotic Arm. Not surprisingly, since it is such a great and inexpensive robotic kit to play with. This project is similar in spirit (i.e, control the Robotic Arm with Arduino), but different in the approach.</p>
<p><iframe width="678" height="381" src="https://www.youtube.com/embed/7docrKlnpbA?feature=oembed" frameborder="0" allowfullscreen=""></iframe></p>
<p> </p>
<p>The idea is to be able to <strong>control</strong> the Robotic Arm <strong>wirelessly</strong> using <strong>gestures</strong>. Also, I tried to keep modifications of the Robotic Arm to a minimum, so it could still be used with the original controller.</p>
<p>Sounds simple.</p>
<p>What it ended up being is a three-part project:</p>
<ol>
<li>A glove fitted with enough sensors to control a <a href="http://bit.ly/1UhB2tm" itemprop="url" target="_bank" title="LED"><strong>LED</strong></a> and 5 motors</li>
<li>An Arduino Nano based transmitter device to accept control commands from the glove and send it wirelessly to the Arm controller device</li>
<li>An Arduino Uno-based wireless receiver and motor control device attached to the OWI Robotic Arm</li>
</ol>
<h3><strong>FEATURES</strong></h3>
<ol>
<li>Support for all 5 Degrees Of Freedom (DOF) and the LED</li>
<li>Big Red Button – to immediately stop the motors on the Arm preventing damage</li>
<li>Portable modular design</li>
</ol>
<p>For mobile users: the “promotional video” of this project is on YouTube <a href="https://www.youtube.com/watch?v=7docrKlnpbA" rel="nofollow" target="_blank">here</a>.</p>

<p><strong>INTRODUCTION & OBJECTIVES:</strong></p>
<p>I is a simple system, using <a href="http://bit.ly/26nCm2w" itemprop="url" target="_bank" title="Arduino"><strong>Arduino</strong></a> to automate the irrigation and <a href="http://bit.ly/1PhV7d2" itemprop="url" target="_bank" title="watering"><strong>watering</strong></a> of small potted plants or crops.<br />
This system does the control of soil moisture, doing indications via LEDs and in case of dry soil emitting a alarm beep. In case of dry soil it will activate the irrigation system pumping water for <a href="http://bit.ly/1Ug9zrI" itemprop="url" target="_bank" title="Arduino Automatic Watering System"><strong>watering</strong></a> plants.<br />
The system uses a LCD display to notify all actions that are taking place and a real time clock.</p>
<p>The Theory (from Wikipedia):<br />
Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, fruit, or wood. Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials’ porosity at saturation. It can be given on a volumetric or mass (gravimetric) basis.<br />
Volumetric water content, θ, is defined mathematically as:</p>

<p>where  is the volume of water and  is the total volume (that is soil volume + water volume + air space).<br />
Gravimetric water content<a class="ext-link" href="http://bit.ly/1Ug9K69" rel="nofollow external nofollow" target="_blank">[1]</a> is expressed by mass (weight) as follows:</p>
<p>where  is the mass of water and  is the bulk mass. The bulk mass is taken as the total mass, except for <a class="ext-link" href="http://bit.ly/1PhV4Ot" rel="nofollow external nofollow" target="_blank" title="Geotechnical">geotechnical</a> and soil science applications where oven-dried soil (, see the diagram) is conventionally used as .<br />
To convert gravimetric water content to volumetric water, multiply the gravimetric water content by the bulk <a class="ext-link" href="http://bit.ly/1Ug8Re4" rel="nofollow external nofollow" target="_blank" title="Specific gravity">specific gravity</a> of the material.<br />
In <a class="ext-link" href="http://bit.ly/1PhUDnl" rel="nofollow external nofollow" target="_blank" title="Soil mechanics">soil mechanics</a> and <a class="ext-link" href="http://bit.ly/1Ug9aFx" rel="nofollow external nofollow" target="_blank" title="Petroleum engineering">petroleum engineering</a>, the term water saturation or degree of saturation,  is used, defined as</p>
<p>where  is the <a class="ext-link" href="http://bit.ly/1PhUzDV" rel="nofollow external nofollow" target="_blank" title="Porosity">porosity</a> and  is the volume of void or pore space. Values of <em>Sw</em> can range from 0 (dry) to 1 (saturated). In reality, <em>Sw</em> never reaches 0 or 1 – these are idealizations for engineering use.<br />
The normalized water content, , (also called effective saturation or ) is a dimensionless value defined by van Genuchten<a class="ext-link" href="http://bit.ly/1Ug9RPc" rel="nofollow external nofollow" target="_blank">[2]</a> as:</p>
<p>where  is the volumetric water content;  is the residual water content, defined as the water content for which the gradient  becomes zero; and,  is the saturated water content, which is equivalent to porosity, .</p>

<p>In the Pictures you have an overview of the components used.</p>
<p>Data from the soil moisture sensor set:<br />
When the soil is dry, the impedance will be high and the LM-393 will show a high value on the output.<br />
When the soil is wet, it will show a low value in the output.<br />
The 3 LEDs range can be defined as:<br />
– Soggy soil –  moisture between 0 and 500;<br />
– Wet soil – moisture between 500 and 800;<br />
– Dry soil – moisture between 800-1023;<br />
The module has one digital output and an analog output. (in the project, should be used to analog output)</p>
<p>The water level sensor:<br />
This sensor must be made (homemade) on phenolite board, with spacings of 1 mm between trails and trails with 1 mm of thickness.</p>

Logically, as the system has an hour  pre set to operate, you can change the time via software for the time you will do the tests, and after you can adjust the operational “time”.</p>

<span lang="en" xml:lang="en">Project started, …</span><br />
<span lang="en" xml:lang="en">I tried to find various references, and began designing electronic diagrams, using components include:</span><br />
<span lang="en" xml:lang="en">1 unit of the Arduino Nano</span><br />
<span lang="en" xml:lang="en">5 micro servo with metal gear</span><br />
<span lang="en" xml:lang="en">3 units of hi-torque servo</span><br />
<span lang="en" xml:lang="en">1 set the mechanical Pivot X – Y to 2 standard servo (used in the wrist)</span><br />
<span lang="en" xml:lang="en">6 flex sensor (5 for the fingers of the hand, 1 for the sleeves)</span><br />
<span lang="en" xml:lang="en">1 unit of 6 DOF IMU (3 dof Gyroscope + Accelerometer 3 dof)</span><br />

<p><img alt="" class="alignnone" height="621" src="http://bit.ly/1PhUYXd" width="614" /></p>
<h2>PROGRAMMING</h2>
<p><span lang="en" xml:lang="en">For his code I created like this:</span></p>
<p><span lang="en" xml:lang="en">COMPONENT</span></p>
<p><span lang="en" xml:lang="en">FLEX SENSOR, I use like this, length 4.5.3″. </span><span lang="en" xml:lang="en">At the foot of the flex output sensor, I attach the PCB.</span></p>
<p><img alt="" class="alignnone" height="363" src="http://bit.ly/1Ug9yEa" width="614" /></p>
<p><span lang="en" xml:lang="en">The workings of flex sensors, on the second output is in the form of resistance ranges from 10-22 k ohm, which changed when flex sensor it is bent.</span><br />
<span lang="en" xml:lang="en">The more bent, the greater the resistance value.</span> <span lang="en" xml:lang="en">More information about flex sensor can be read here.</span></p>
<p><span lang="en" xml:lang="en">Then flex the sensor I am sewing in motorcycle gloves made from the fabric.</span></p>

<p><span lang="en" xml:lang="en">HIGH TORQUE SERVO, servo-I use this because it has a much better strength than standard servo.</span><br />
<span lang="en" xml:lang="en">MICRO SERVO WITH METAL GEAR, this servo is used to drive the fingers of the hand.</span> <span lang="en" xml:lang="en">Although this small servo, its power is quite good because it already uses the gears of the metal.</span> <span lang="en" xml:lang="en">(generally uses plastic gear servo).</span><br />
