As a very cool present, we got an actual oil boom to test with.<br />
<br />
Also, we are nearing the end of our semester and are therefore presenting our work at our final exhibition at TU/e. We will be presenting our work on Thursday June 7th, form 9.30 to 11.30 and on Friday june 8th from 13.30 to 15.30 in the Next Nature Theme (that is in the purple space on the 4th floor of the main building of TU Eindhoven) you are very welcome to come visit us and see our work.<br />
<br />
Thanks for reading,<br />

<br />
As many of you are aware, Protei wants to build an autonomous sailing fleet. For this dream to come true, Protei requires models of swarm behaviour, in order to predict what would happen to their fleet without actually trying it out with a possible result of crashing.<br />
<br />
Keeping this thought in mind, I started developing a Swarm Model Testing Area, using a powerful engine called Netlogo. That said, I would like to share with you the first version of this model, and I would like to ask you to share your thoughts on it. Before you ask: Yes, it is a work in progress and no, the boats do not have a clue where they are going (yet). The next version (probably finished by sunday) will include flocking behaviour by the boats. By following the next link, you can access the model and start playing about!<br />
<br />
<a href="http://www.pieterbron.nl/swarm/Swaaarm3.0.html" target="_blank">The Swarm Model</a><br />
<br />
Also, a Version log is available here: <a href="http://www.pieterbron.nl/swarm/VERSIONS.txt" target="_blank">Version Log</a><br />
<br />
Bear in mind that the dropping of oil isn't considered light-weight by this engine. It might take a while before the model reacts again. I am looking into that.<br />

We already introduced our idea of seeing Protei boats as
a species in the midterm presentation. (A video can be found below) As
mentioned in the presentation we chose to design the genes of the boat, that
will make it possible to function in the group. This design will be in the form
of a pilot, using input from sensors to navigate and operate the boat. Having a
standard ‘brain’ for Protei boats that comes in a kit with sensors improves
functionality an compatibility of homemade boats.</div>
<div class="MsoNoSpacing">
<br /></div>
<div class="MsoNoSpacing">
But organisms are more than genes (software) and a brain
(core computer). Vital organs are of equal importance to ensure quality and
sustainability of life for the Protei species. We believe that problems like
bad maneuverability can be reduced by adding innovative organs (plug & play
boat parts) to the kit. Expert assured us that it is impossible to address all
problems properly within our limited time span, therefore we have to make choices.</div>
<div class="MsoNoSpacing">
<br /></div>
<div class="MsoNoSpacing">
This week we are finishing the pilot/brain prototype to
be tested next week. Several different sample boats are being built at this
very moment to test the pilot in different settings. The plan is to start
concretizing the first ‘organ’ after this test. An example of a possible
‘organ’ is a interactive counter weight that makes it possible to get more
energy from the sail and still lay flat in case of storm.</div>

has as a goal to create a vessel that can “live” autonomously and that
can perform tasks as a swarm. In this description, we found similarities
with the properties a species has. We are, at least for our project,
proposing to approach our activities in the Protei project as if we are
designing a newt species.Viewing Protei as a species provides us with
design opportunities (or research questions). </span></div>

we will set the properties apart that the new species should possess
and how these properties will, according to us, apply to Protei. We do
not want to base these properties on any specific sort of species, but
more on general aspects of nature to have a framework on which we can
build up our Protei version and through which we can find opportunities
to develop all of Protei’s functionalities. This framework is dynamic
and the properties inside it can therefore be changed and new properties
can be added.</span></div>

individuals get born. In the case of a Protei, this will happen through
an interested contributor, building their own Protei. The design
opportunity for this aspect lies in how the information of how to build a
protei will be obtained. Designing a building kit is an interesting
opportunity. Others are to create a better, clearer community where
information about Protei is distributed. This way of working will create
a ecosystem of similar but not identical Protei individuals and
biodiversity may be a positive side effect.</span><span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: bold; text-decoration: none; vertical-align: baseline;"></span></div>

will for example help birds who are covered in oil. While this is a
rather extreme example, it might be more realistic to have Protei

can, for example, deliver software updates to each other. But maybe also
between Protei and “natural” species.</span></div>

<span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">At
the midterm presentations I want to present my research and my first
ideas of group behavior. In the presentation I will show a visual of the
environment in which the drones will be placed. This visual will
include all the important aspects of the ecology. It displays the flora
of the region, the fauna and also the influence of humans in the
environment. The research I did on swarm behavior will be summarized and
presented. The main point I will hope to receive feedback on is my
ideas for swarm behavior. So this will be the key part of the
presentation.</span></div>

the final exhibition I want to make a visual model that accurately
displays a Protei swarm cleaning up oil spills. In the most ideal
situation I will also have a small scale physical swarm that can execute
swarm behavior on a small scale. Using the data a gathered about the
swarms and the environment I will make a design for the drones. This
design will be based on the tasks that the drone has to accomplish, the
environment and the swarm behavior. It will not be restricted by current
technology or feasibility. </span></div>

personal direction for this project is to get an understanding of how
the boats communicate with each other. Growing up on a farm, I’ve always
been around animals and I want to research their communication and
integrate it in the communication of Protei. By looking at how animals
communicate with each other to hunt or to prevent from being hunted
upon, I want to create a ‘language’ for the Protei that is stripped down
to its essentials. They should only communicate if they have to, so
there should be as few rules as possible to ‘hunt down’ the oil-spills.</span></div>

the midterm presentation my goal is to finish research on animal
behavior and make a computer model in Processing in which the Protei
already have a basic intelligence to communicate where to find the oil
and absorb it.</span></div>

suit the Next Nature theme the project is in, the main focus of the
project will be looking at wild robots as a species of its own. This
focus will be applied on the client Protei, there sailing boats will be
seen as a species that reproduces, responds to stimuli, evolves, shows
collective behaviour and is able to live in symbiosis with other
species.</span></div>

this point the general understanding is that the protei species will
reproduce itself by people that buy parts or a set/kit of parts (could
be partially pre-assembled). The assembled product should be able to
find its way to a swarm autonomously, allowing users to put it into the
water anywhere. To reach a realistic design in these aspects, attention
needs to be paid to compatibility and affordability.</span></div>

design opportunity in this is to design a basic boat assembly with kits
available worldwide. The boat and kit itself need to be designed in a
way that the final assembly will be very simple and low cost for all
users. When designing the kit the functionality needs be designed to be
pre programmed. This is necessary to assure compatibility with the whole
protei swarm. After designing the physical and operational part there
is also a marketing/ business area that is to be designed. To give a
clear image of what actions are needed to accomplish the reproduction of
the Protei species business models are also needed.</span></div>

<br />
Over the past 2 project-weeks, various brainstorm sessions, discussions and research have been performed in order to get a clear view on what we want to get out of this project. On the right are the possible directions we've come up with on Monday the 13th of February. We've also performed a brainstorm session that day with random items, to see whether new ideas sprang to mind using these items.<br />
<br />
After these brainstorm sessions, it became clear that we want to focus on the Artificial Intelligence, especially autonomous sailing and swarm control. How can we ensure that a fleet of - for instance - 10 vessels can harmoniously work together without crashing each other.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://4.bp.blogspot.com/-d4FQEWYPi3A/T09vfnQKuCI/AAAAAAAAACU/9Rez5W82-h4/s1600/_MG_5617.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="265" src="http://4.bp.blogspot.com/-d4FQEWYPi3A/T09vfnQKuCI/AAAAAAAAACU/9Rez5W82-h4/s400/_MG_5617.JPG" width="400" /></a></div>
<br />
We then continued searching for the optimal building solutions in order to create an easy, yet efficient sailing drone.<br />
<br />
<b>Options</b><br />
- One sail instead of two sails. If you build a gaff rig up front of the drone, you can get proper pulling power without extra control difficulties.<br />
- A canting keel aids the boat to stay at a more horizontal level, ensuring a bigger surface to catch wind in the sails. We might look into this in the future.<br />
- We might want to use a special material for the sails: There exist a very tin fabric of solar panels which can be used as a sail. This way, you have a big surface where energy can be caught to charge the batteries. This is also for in the future.<br />
<br />
<b>Plan for now</b><br />
Our plan is to build a quick and easy sailing drone. We then want to actuate it by using servo's etc., while the final step will be autonomising it. The specs for this boat will be uploaded soon.<br />

<b>The idea</b><br />
<b><br /></b><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://4.bp.blogspot.com/-sysofPef7gM/TzjSc5kwOVI/AAAAAAAAAAw/Ysu4pW6lmwc/s1600/_MG_4746.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="213" src="http://4.bp.blogspot.com/-sysofPef7gM/TzjSc5kwOVI/AAAAAAAAAAw/Ysu4pW6lmwc/s320/_MG_4746.jpg" width="320" /></a></div>
Exploring different ways of steering while maintaining the maneuverability of the boat was one of our first iterations to start-up our project. Brainstorming sessions resulted into the concept of the Banana-boat.<br />
<div class="separator" style="clear: both; text-align: center;">
</div>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://3.bp.blogspot.com/-WSOhufo-CWY/TzjSh2IZBkI/AAAAAAAAAA4/kRXPoiLJXOs/s1600/_MG_4745.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="213" src="http://3.bp.blogspot.com/-WSOhufo-CWY/TzjSh2IZBkI/AAAAAAAAAA4/kRXPoiLJXOs/s320/_MG_4745.jpg" width="320" /></a></div>
The idea is that the front of the boat is rounded and shaped upwards, providing lift when the boat is moving forward. Upon taking corners, the front will rotate 90 degrees to the left or to the right, putting a rounded rudder in the water, resulting into the boat taking a corner.<br />

<b>Construction of this prototype</b><br />
<b><br /></b><br />
<b><i>Sail</i></b><br />
Cut an iron bar with a length of 55 cm. Cut another iron bar with a length of 30 cm. (Diameter of 2.5 mm was used on our prototype) Now solder the 30 cm iron bar on the 55 cm, at a distance of 10 cm at one end of the larger bar. Solder it 1 cm from the end of the small bar.<br />
<br />
Measure the required size for the fabric. (Differs per fabric as some are more elastic than others.) Then, punch 6 holes in the fabric where the rings should go. (Look at upper picture for reference.)<br />
<br />
Punch iron rings (Grommets) in the holes, leaving you with the following.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
Note: One of the holes is still missing here. See earlier picture for sixth grommet position.<br />
<br />
Use tie-wraps to connect the 5 grommets on this picture with the iron bars. Finally, solder a third iron bar right between the other two iron bars and connect the sixth grommet to it with a tie-wrap.<br />
<br />
<b><i>Boat</i></b><br />
Use foam to construct the boat. Construct a shape that looks like the following picture.<br />

<br />
Length is approx. 60 cm. Rudder is 10 cm, diameter of the hull is 8 cm. Next, cut this construction in half. Create a wooden cylinder with a thickness of approx. 3 cm, with the same diameter as the hull. Create a hole on top of this cylinder and punch your sail in it. Connect the cylinder with the rear side of the boat. Glue/duct tape/however you wish together.<br />
<br />
Create two more slightly curved rudders. Glue these on the front part of the boat, in line with the curve in the boat itself. Glue them on a 90 degrees distance from the main rudder. Connect it up with the unused side of the wooden cylinder by sticking an iron pin inside the cylinder, then punch the foam front on this iron pin so it can rotate.<br />
<br />
<b><i>Keel</i></b><br />
Create a wooden keel, fill it with lead (approx 1,5 kg) an stick it on the opposite side of the wooden cylinder compared to the sail.<br />

<span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">With
this prototype, we wanted to explore the shape changing hull as it was
introduced in earlier Protei boats. To do this we decided to build a
hull that moves its body like a snake. The hull is made of foam and its
movement is controlled by servos attached to an arduino.</span><br />

<span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">We constructed six equal pieces of foam for the snake’s body, a head and tail where also added. </span><br />

<span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">First
we tried making the joints form soft foam, this turned out to be to
flexible. The joint being to flexible caused the snake to bend also in
different directions as it should.</span><br />
<span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;"></span><br />
<span style="background-color: transparent; color: black; font-family: Arial; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">In
version 1 of the prototype (see movie) we used square joints made of
the same hard foam as the rest of the body is made of. These joints
worked better but made the movement of the snake a lot less smooth.
Therefore we chose to use triangular joints (version 2 in the movie).</span><br />

we are going to use this technique in the future we should look into
using less servos to make a complete body move (with energy efficiency
and simplicity in mind).</span>ID.proteihttp://www.blogger.com/profile/14826409380389628825noreply@blogger.com0tag:blogger.com,1999:blog-3906342032096612606.post-20059497072429158672012-02-08T10:45:00.000+01:002012-02-08T10:46:32.491+01:00Skype Meeting with Piem WirtzAt 16:00 on Monday, we had our first meeting with one of the members of the Protei team.
