First test sailing Boat

First test in the water today!
Unfortunately I broke the rudder by pulling it to hard, so I won't do this abusive behavior anymore in the future, but i am also reinforcing the rudder at this moment.

For now: 

next update monday evening. hopefully with a fully remoted controlled boat on a larger lake!

Remote controlled sailing vessel!

At this moment the sailing vessel can be remotely controlled, today I did a quick test, but more keel ballast needs to be added so that's my task for this afternoon. For this moment I can already show the mechanics of the boat. See video below.

Imtech marine + skype meetings

During the weekly skype meetings with our client and the meetings with the community on monday some interesting things come up. This blogpost will summarize the most interesting things of the past few weeks in these meetings.

DEAF 2012
during the meetings at the start of the project the agreement was made to present our results at the Dutch Electronic Arts Festival 2012 (short DEAF), this event on the 17th of May will be a podium to show our development for the protei community and also let us discuss our results with a lot of different people from within different fields of interest to widen our view on the project.



No flexible hull for protei TUE
During the meetings we decided to not use the flexible hull mechanism in the protei project at the TU/e this decision was made to save time with building the ships and start thinking about intelligence and user involvement as soon as possible

Imtech
Imtech marine has first hand experience with building autonomous sailing boats. They were interested in the work we do at the TU/e and contacted Piem Wirtz who brought Mart Hurkmans in contact with me.

I made an appointment with Mart Hurkmans for the 10th of April to meet at Imtech Marine in Rotterdam.
In this appointment we can discuss the possibilities of working together on some parts and how we can use each others knowledge in the design process.

Also I asked other fellow student if they wanted to join me to visit Imtech marine and probably 4 students will join me.

Protei project concept ideas


Concept
The strength of the Protei project is the community behind it. To extend this community I want to design a autonomous sailing vessel which is easy to build yourself or cheap to manufacture. Building different sailing vessels can create a large community of people working on the same problem but when the boats are finished I don’t want to lose this community, so the concept is based on the user interaction starting from when the boat is finished to the very end of its life.

Because autonomous sailing isn’t so easy yet (http://www.ssa.ethz.ch, http://www.sciencedaily.com/releases/2009/01/090119113903.htm) I will not aim to make this boat completely autonomous. This makes it also possible for the community to stay connected to their own boat after it hits the oceans. By adjusting the parameters of the boat (parameters which influence how fast the boat makes the decision to make a turn for example) and routing the boat to places with a large oil spill, it is possible to influence the boat even in the middle of the ocean.

This opens the way for serious gaming. Real sailing vessels remotely controlled by the community who build it. For now I want to investigate what kind of rewards can be given (cleaning up oil is valuable for governments and companies like BP)  and if the rewards should return to the protei project or can be withdrawn. 

building a 1m sailing vessel

During the past 2 weeks I build a sailing vessel of PVC. at this moment the sailing vessel is almost finished. All parts are build and the actuators are placed, but at this moment the boat needs to be remote controlled which isn't implemented yet.

Below i show the building process of the sailing vessel:


I started building with a PVC pipe of 125 mm and heated this with a hot gun to shape it in the shape of a sailing vessel

Instant succes not guaranteed  

After some time you will get this shape by cutting of half you will get a better shape
Me cutting of half of the pvc

Not instant good result as well a little adjustment to make it better.
 
After heating the PVC again it comes close together but pvc is made based on a chemical reaction so the parts will never glue together by heating. Therefore use PVC glue to glue the parts together.
 
Close up of the glued parts



Time to make the sails:
the sails are made of old sails from a optimist (small sailboat for children).
this sail is cut in to the right shape. 
The shape which I chose is Gaff rig (see wikipedia: http://en.wikipedia.org/wiki/Gaff_rig)

with zeil ogen (dutch word and untranslatable by google translate.. but those are the metal rings in the sail)
you can attach the sail to the mast. The mast is made from aluminium pipes see pictures. The measurements of the sail will follow later on.
Height mast:
width:
angle gaff rig:
length gaff rig:


attached gaff rig to the mast.

time to attach the keel as well. to attach it as good as possible I decided to put them inside the hull of the boat and attach them to pieces of plywood which are glued to the hull itself. This resulted in a very strong and rigid connection. 
 
after attaching the keel everything is sealed with silicone to make the connection also water tight. 
 
after the connection of the keel, the rudder could be connected as well. In this case the servo is mounted upside down in the hull and a wooden stick is attached to the turning mechanism of the servo.  the wooden stick is connected to the rudder (see below: left keel, right the rudder) and connected to the keel to share the weight of the rudder and to keep it more stable. 
 
 
after closing the back side of the sailing vessel you have a water tight boat.

good luck with building one yourself!

more pictures and explanation will follow soon.




Go-Tan designbrief



Guerrillaz Design project for Go-Tan 
This week I had a meeting with Guerrillaz marketing, they worked for a large company which sells Chili sauce and prawn crackers (dutch: kroepoek). During this meeting it became clear what our task would be, together with Jesse Meijers and Liza Blummel, I have to design a chili sauce dispenser which can be used on festivals and racing events across the country. The idea behind this is that Hot  chili chicks (the promotion ladies) give away free chili sauce at these events and through the design of the chili sauce dispenser we have to communicate the values of the company, also it has to be fully functional and produced within 1 month, which is quite a challenge.

below the most important parts of the design brief in dutch:


Opdracht:
Design een chili dispenser die door promotiedames gedragen kan worden en de doelgroep op festivals kan voorzien van chilisaus bij hun snacks.
Termijn waarin het product af moet zijn is ongeveer 1 maand, na deze maand wordt er een werkend prototype verwacht van het product. Met een kostenplaatje van de productie kosten.
Aantal uur werk wat verwacht wordt is nog niet bekend, wat resulteert in een onbekende verwachting van de kwaliteit van het prototype, ook het budget is onbekend op dit moment.
Company profile:
Wij, Go-Tan, zijn een professioneel georganiseerd maar klein familiebedrijf dat met liefde en toewijding wordt geleid door de zoons van oprichter Frans Go. De familie Go kwam in de vroege jaren vijftig naar Nederland vanuit de stad Bandung, op het Indonesische eiland Java. Behalve deze Indisch-Indonesische herkomst, heeft de familie ook een Chinese oorsprong. De combinatie van eetculturen, maakt deze familie tot het levende motto: A very foodloving family.

Solidworks

Last semester I made the conclusion that a lot of companies require the skill to work with Solidworks, also 3d printing and a lot of manufacturing proccesses require a solid model (instead of surface modelling) for example from Solidworks.

This is the reason I started with SolidWorks last semester by making a model of my Led Clock, however last semester, the work was mostly done by a fellow student, Jesse Meijers.

This semester I worked on tutorials and joined 2 workshop evenings, in which the possibilities of SolidWorks became clear to me. Also the speed in which I could design these products was impressing. Below I will show some renderings of my work during these tutorials and at last I will show the design of the LED clock in solidWorks.

 First step, making a perfect sphere.

 A glass shape on a table.
 making a mold for a rugby ball or just any item.
 wrapping text on a object
add product properties to a complex shape
and finally the Led clock with the handle to adjust the alarm clock.

Personal input and learning goals


During this project I will focus on the intelligent behavior of the boat. I want to accomplish this by creating behavior for different parts of the boat, and when all different parts come together it results in autonomous sailing drone. To accomplish this I need to design the interaction of the boat with the wind and waves. Also I want to get more experience with building prototypes with high quality and drawing 3d sketches in SolidWorks. Also I want to create a wider view on the protei project as a whole and develop a concept which involves user interaction with my system.

Ideas and concepts
The development of the concept and user involvement is strongly connected with this competency area. Also the brainstorms in the (kan niet op het woord komen maar het project in 1 week uitvoeren fase) were important for me. I researched different methods and techniques and applied several of them which were very helpful


Integrating technology
will be an important part of the development of an autonomous sailing boat. I will not focus on this but for me as a designer it is important to work with technology and to be strongly dependent on the available technology. Making intelligent behaviors for each part of the boat will be the biggest challenge.

User focus and perspective
The design for this boat should be made from within the perspective of the user. These boats will clean-up oil spills so the health of the staff on boats which clean up the spills now will not be endangered but also all the people and animals ashore will be less harmed by the oil spills. Therewithal the user is also very important in the development of the concept and how the behavior of the boat will be influenced by the user. These decisions must be made with a strong user focus.

Socio cultural awareness
when I start to look into the business model of protei I can address this competency area in this project. I can research how people at the other side of the world want to build there protei and what there motivation is to do things and adapt also the interface to this fact. But I think I will not address this during this project, but I will discuss this with my coach.

Designing business processes
The protei community is not a standard business platform but a opensource hardware community, this however doesn’t mean you can’t make profit of the products which are created on this platform. Only another approach is necessary, in this project I will look at this but it’s not a very important part for me yet.


Form and senses
This competency area isn’t very important for the boat itself, the form has to be mainly functional, abstracting these functions to their basics helps making the boat more simple, also the interaction should be designed and the senses of the boat need to be somehow translated to an interface which is easy to understand and influence. Which is very important for the user experience in the end.

Multi-disciplinary Teamwork and communication
In this individual project, I will work on my own project, but be closely related to my team and also the other teams and master students working on this project. Also managing the contact with the client and community of Protei will be done by me. The goal is to also use this community in the design process and design decisions but the quality of the feedback need to be good and given fast (not after several weeks) to be used in the design process. If this is also feasible needs to be seen.

Design and research processes
In this project I started with a pressure cooker, a new technique for me to start a project which helped me a lot. The research phase is largely finished now but I still have to find out how to make a object intelligent, what is the standard for this and how can you program these self-learning-algorithms. To find this out I want to speak with experts and read documentation about these technologies (already read “making things talk” to address this).

Self directed and continous learning
Since this is an individual project I will work alone on my prototype and concept, but I will continue to use the input of experts and fellow students in my project to learn from them and see other valuable insights.

Analyzing complexity
What I want to do with programming behavior can only be done, if I understand the complex system behind sailing. This complex interaction between the boat, water and the wind is constantly changing and I need to analyze this and come up with a set of parameters to control the boat. After this I also have to find out how to adjust and influence these parameters and which data I will need to adjust this to the right value. Building a complex system requires thus also to analyzing and understand the system you are building in.

Project planning and Deadlines

This document describes the goals for my development this semester in my project and shows the mapping between the actions in my project and my competency development.


Goal:

In this project I want to achieve, that users are able to manage their own fleet but not control it directly. The goal of the boat is cleaning up oil spills on the ocean, which can be done very efficiently with the techniques which are already developed in the protei project.
My input:

For this project I have to design a cheap boat, build from off-the-shelf components, which can maneuver independently and autonomous. Also I need to develop the concept of the user involvement and the way he can control his own boat or fleet.

Deadlines:

23th of march, mid-term,

For the presentations on the mid-term I want to have a finished boat which can sail remotely controlled and have a set-up for the user involvement concept. This can then be presented at the mid-term presentations. 


May 17th, Dutch Electronic Art Festival (DEAF), 

At this moment (3 weeks before the final exhibition) I have to present my concept at DEAF, which will cause that my prototype has to be finished at least to the point that on the exhibition floor the concept and functions of the sailing vessel becomes clear. And even more important the user interface must be finished because the user (and public) will mostly interact with the interface and not with the boat on the middle of the ocean. A clear presentation/pitch must be finished to give a clear idea of the concept of the product.

Final exhibition, 

This is 3 weeks after Deaf, in this time the report and reflections will be made and also a set-up of my showcase to address my C-condition (I’am already working on this in the evenings). Also the communication between the other ships which were build in the protei community and mine can be addressed in these weeks.

User testing assignment reflection


Research Question and user group
I found out that working on a user test is mostly about the preparation, a good research question is the start of this. How the research question is formulated highly influences the outcome of the user test and how valuable these findings are. Because the preparations are so important we put a lot of time in it. This worked out but didn’t put enough effort in determining which user group would give the best results for our research question. This was mostly caused because we wanted to find users outside our own social environment (e.g. no students, designers etc). We chose to work with people who own a own house and home theater system. By going door to door in Woensel-Noord we didn’t had much choice in selecting the user group on age, gender, or experiences with devices like media players. This was a pity because we wanted to mainly test if the remote control and interface was intuitive and simple for people who weren’t used to work with these devices. After all we found 3 out of 6 users who didn’t had sufficient knowledge about these devices according to their own judgment. And the average of all users was 5.2 so we had a fairly good group to my opinion.


Usability and user experience
In this assignment we only focused on the usability of the device and the remote control, with a flawless usability we wanted to make the user experience as simple as possible. The device shows the movie or plays the song when needed and nothing else. The design also wasn’t designed to make the user feel happy, but to be simple. However we could have measured the user experience in different ways, for example in the questionnaire afterwards but also by documenting the behavior of the user. The last thing we did during this test but we didn’t analyzed it enough to say something substantiated about this. The user experience however is something which is very important for me as a designer so I should focus much more on this part of the user test.

Set up of the test
In previous user tests I didn’t put much effort in the set-up of the test. I was more worried about the product  and finalizing and improving this before the user test. However in this assignment it became clear that a good thought process in the preparation phase can be much more helpful than a improved product. I learned to think more elaborate about the goals I want to achieve with a test and ways to accomplish these goals. Also concrete describing of the goals and how to measure this helps to get more out of a test. I think due to the guidance during this assignment we had a good preparation phase, nevertheless I can improve on this point by being more concrete and more complete for example including user experience goals in the set-up so this can be used in the development of the product. We chose during the set-up to have a very strict task division which was both very clear for ourselves but also for the users, only 1 person introduced the test and handled the questionnaires etc. which limited the chance on errors by miscommunication between us. In the future I would definitely use the same strict division of tasks.

Paper Prototype
In the past I was always skeptical about paper prototyping, I always thought that using a working
prototype worked better because the user experience would be more real. In this assignment I found out that, because so much is undefined the user is much less distracted by the design and can focus on the product and the interaction. Also it encourage users to be more creative with the interaction or even think along in the development process because they can clearly see that the product isn’t finished yet. And this information can be really valuable for me as a designer. Also working in a early stage on a paper prototype helped me in defining what was important on (in this case) the remote control and interface. If I would only write it out on paper I couldn’t test it myself and would miss things which are hard to
implement afterwards on a more sophisticated prototype. After all I expected this remote control and interface to be very basic and unreal but after all there were 2 user who thought after working with the interface that the remote control was actually a working device (although they thought it was a bit lightweight).

Thinking aloud and Co-operation
I think that these methods can be very valuable for a user test because you can also derive data of thoughts people have and of things you didn’t think of yourself as a result of the test. But because the methodology has such a rich potential amount of data we didn’t got everything out of the method. This was mainly because we didn’t know what to expect and thus improved with every new user test we did. For example the explanation of what was expected from the user became more and more specific so the users had a good understanding of the method. In the co-operation the effect of what people thought was less present because people tended to only say something when they knew it for sure so mistakes weren’t less noticed because most of the times one out of 2 knew the right button to click and was first to mention it. But it showed that with a little help of a inexperienced person every task could be
completed.

Consistency
In this assignment I performed my first real user test with non-Industrial design students. This made it more difficult to explain to the users what a user test was in the first place and what was expected from the user. We scripted the lines to explain this to the user, but due the differences in users I had to elaborate on some parts, which led to inconsistency between the information the users got at the start of an user test. Also during the user test some mistakes were made because the arrow appeared to soon or moved to soon and by this indicated the next step the user should take. This influenced the results and therefore we should be aware of this influences. I don’t think we would gather significant different results but in the future I want it to be more consistent especially for this kind of user tests with real users instead of fellow students.

Future
User testing will be an important part of designing for me. This assignment gave me the theory basis I needed to develop myself further in this direction. During my upcoming project and eventually assignments I can use this knowledge, but I want to develop myself the most in how to test user experience, when I read articles on the internet the experience and usability are often confused with each other so I will look for good documentation about this before I conduct my next user test. Furthermore I want to use paper prototyping in earlier stages of my design process. In my current process this isn’t possible anymore, but in my next project I will definitely use the techniques I learned in this assignment.

directions for the project as a group

Directions for Rik Bootsman, Pieter Lobbezoo & Pieter Bron

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. 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. We then continued searching for the optimal building solutions in order to create an easy, yet efficient sailing drone.

Options
 - 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.
- 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.
 - 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. The plan for now 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.
