Launch of Protei, oil spill cleaning open hardware sailing robot.

https://www.kickstarter.com/projects/cesarminoru/protei-open-hardware-oil-spill-cleaning-sailing-ro

Dear fellows. We just launch yesterday Protei on Kickstarter.

Please share the link to our Kickstarter on your facebook, or if you know people in
- environmental justice

- sailing world

- DIY

- open-source

- engineering

Protei is a fleet of Sailing Drones, developed primarily to collect Oil Spills under Open Hardware licensing. An oil spill drifts down the wind, Protei sails upwind to collect the oil. Everyone is welcome to join, contribute, modify, produce, distribute the design and share their findings.

You can watch the 3 minutes video under to understand the detail of how it works :

The technology is really exciting beyond the fact that it could help for ocean study and cleaning.
Have a lovely TED2011!

Presenting Protei @ TEDxMidAtlantic

A few days ago, I was lucky to be on stage of TEDxMidAtlantic to present Protei, a technology in development I am working on with a bunch of brilliant people (especially Open_Sailing, randomwalks and V2_ folks).
Protei would be a Fleet of Oil Collecting Sailing drones. I just made this 7 minutes video that explains how it works (also on youtube if you want to share / embed / rate). I am now working on the collaborative website and the documentation to meet Open Hardware standards - long way to go :) The video of the talk may come up sometimes, meanwhile you have my explanation here :)

Test of Protei-003 (3m long, 6.5 meter high, 25kg total, 18kg ballast) didnt go that well ... hum hum... The mast feet broke, not enough triangulation I guess... the ballast didn't affect the direction enough (too flexible keel) ... and there was no wind (HAHAHA) just enough of a beautiful sun to make really romantic pictures, the best one below by Hunter Daniel. BUT we learnt a lot and Protei-004 will be Übercool! Can't be bingo every time, right :) For those who don't know about Protei : it is a fleet of semi-autonomous sailboat that are specifically designed to pull long heavy loads, long oil-absorbant booms to collect oil spill. http://protei.org You can also check out the previous test machines that led us to this design : Protei-002 (entirely articulated RC boat), Protei-001 (front-steering boat).

And now time travel : from the navigation back into the making :

Based on the T37 of Tippecanoe Boats : http://modelsailboat.com

Protei is an unmanned articulated sailboat designed to pull heavy loads upwind, in particular oil absorbent boom as a "long tail", to clean up oil spill in remote areas or in bad weather. Protei is needed to replace human labor exposed to toxic pollutant and in hurricane time.

Protei-002 is an articulated robot, the test went OK. I had to trim the sail smaller, add weight at the ballast, make the electronic access higher to allow more lateral tilt. The fact that the electronic is not well protected is a big problem : as soon as there is too much wind, the boat tilts a lot and fills with water, so I was not able to conduct extensive testing, quickly I had shortcuts on the machine. For those who didn't see, Protei-001 was a super cool front-steering robotic sail-boat. Time is running out, instead of working more on Protei-002, I'm building Protei-003, inflatable, bigger, stronger, faster, more powerful, coming soon !

Protei-001

Yesterday went testing Protei-001 on Lake Pontchartrain (New Orleans LA).
What's so special for Protei-001? It is a Front-Steering Remote Control Sailing Boat (the rudder is right a the front of the boat).
First tested without a tail, and with the tail (about 4 meters). Without the tail, the maneuverability is amazing ; with the tail, the control is pretty good, much better than with a classical back rudder sailing boat. The aim is to make a powerfull yet simple semi-autonomous sailing boat with a high pulling capacity - in the case of Protei it is a long oil-absorbing tail that cleans an oil spill.

Bay Jimmy, post-oil spill observation

Second post but first large map using the techniques of Grassrootsmapping.org for LA Bucket Brigade – thanks guys for putting this wonderful DIY technology together. So! In the late morning 22nd of July 2010, Hunter Daniel and myself went to map out of Port Sulphur, on these funky boats :

With 2 boats we took this route (see google map) :

I traced this route with my mobile phone Google Nexus One and the fantabulous Open GPS tracker for Android – 4 stars rating!
This is what we could see from the boat, kinda boring :

Soon after I launched a balloon and Hunter a kite out there, kinda exciting :

we captured nice pictures, here 6 details :

These 6 pictures were made using 270 stills… that was a 12 hours work on photoshop sincehugin (an open-source photo mosaic software) didnt do the trick – yet :/ Still working on it to automate the process and spend more time sipping mango juice
In addition to what we had a bad GPS trace – my bad, I mean, it is good but I did’nt know where we started taking pictures on that route… Also the GPS time-stamp and the camera time-stamp did not match… So, here is the trick I found:

1. stitch approximately consecutive images with multiple layers on photoshop, when your shape takes shape you may guess where you are on the map. If you only have pictures of water, you can make a great water map … USELESS! BOOO! When your balloon/kite is up there, make sure it is flying over what you want to see, for us, the coast line – land and water. Wind is crucial, and because of the sun you want to avoid taking pictures when the sun is too high (reflection of the sky in the water).

2. produce a very high resolution map of the area. I didn’t want to do it all manually and I wanted to figure out a hack that would work on every platform (OSX, Windows, Linux), so here we go :
- find your point of interest on any map system, write down the coordinates of the top left hand corner of the tile you want to produce.
- go to http://pallit.lhi.is/bigice/bigpic.html , from here enter your Lat and Long (me : 29.468400, -89.911300), the zoom, number of tiles etc… hit “submit”. It will produce a huge map with a static URL. In my case the URL that produced the map (everything is in the URL PHP request) you see here :
http://pallit.lhi.is/bigice/supergooger.php?lat=29.468400&lon=-89.911300&zoom=18&x_tiles=40&y_tiles=40

– now you have this huge picture, you need to capture it from your browser, download theScreenGrab! add-on for firefox only – but working on all platforms (download Firefox NOW if you don’t have it, you…!). Now, grab that huge picture with the tiny ScreenGrab! button at the bottom right corner of your browser, save as png or jpg.

3. Now, it is much easier to map with a support map! just keep adding layers on photoshop of all the pictures you took, adjusting, stretching, so it matches roughly google maps – you will often find that land shape changes, trees, rivers, buildings etc… that’s very exciting, this is why we are mapping : everything changes !

Ok, so now we have this huge empty map :

That’s another 6 hours work adjusting 700 pics layer by layer on photoshop ; hey, 270 images in 12 hours VS 700 images in 6 hours => see, it is much faster with a support map! We got that :

Don’t forget to put a scale and cardinal orientation + legal mentions.
So, under your eyes that’s a 17000 x 17000 pixel map, made of 970 pictures taken at 1000ft altitude, depicting about 5 linear km of damaged coastline. Combining the 6 details views and the general map we could observe that the south side was much more exposed to the spill (more dark brown brrrrr). Using this map we could also establish that on the exposed side, even the inland waterways are strongly affected by the spill : we can use these maps to quantify the surface affected by the oil spill, and the mass of crude attached to the surface coastline. Now even cooler, you can see these maps on google earth, download the KMZ file here (dont worry it is a tiny file – all the content is online). FLY !

Apart from mapping this catastrophe – which is very useful for scientific study and for lawsuits against BP- why am I personally learning aerial photography? Well, because I am currently designing an oil collecting robot called “protei“.

Protei is a sailing semi-autonomous robot with a long oil absorbing tail. Surface oil drifts downwind, so Protei sails upwind, taking and taking, intercepting oil sheens. Imagine many many of these cheap machines out there in the ocean collecting oil

After some research …

I built a steampunk test machine that is pretty promising with a flexible hull front-steering :

We are also testing at sea the behavior of a long tail, and same, going pretty well …

See these little balloons on the surface of the water? And this is when aerial photography comes handy : to evaluate the efficiency and behavior of Protei, seeing everything from above helps a lot, I can see the trajectory, the movement of the tail, the interaction with oil. Also having a highly visible “flying flag” in the sky is amazing to optimize safety and long range communication (flying antenna)… Exciting no? And the challenge is here, millions of liters of crude oil gushing in the Gulf of Mexico, in the Niger Delta, in Latin America, the middle east, in Asia… Protei_Oil_Spill has a busy future!

Of course, just like grassroots mapping, Protei is developed open-source and collaboratively, so I hope that sometimes soon, Protei will come back to land with a lot of amazing pictures for LA Bucket Brigade and its amazing oil spill map, GrassrootMapping,Cartagen and Open_Sailing! I received most electronic parts for the next prototype of Protei_Oil_Spill this morning (YAY!), I am building in New Orleans, so if you are around, or if you want to help the project remotely, do get in touch – cesar@protei.org – thanks!

Grassroots mapping

A couple of days ago, we went with the folks of LA Bucket Brigade (again!) to do some grassroots mapping (aerial photography actually) in the Bay Jimmy & Wilkinson Bayou (29.45193, -89.89812), and it was superb ~ and dystopic :/

> 1.
> 2.
> 3.
> 4.
> 5.
> 6.

Seen from up there is so different from what you see from the water :

We went in those super cool (noisy though) boats :

Boat seen from the balloon (!!!) :

This is how it works :

So we do the same but with a helium Balloon flying at ~1000ft, with a camera attached to it, looking down, taking a picture automatically every 5 seconds or so :

I took a chance to try to enhance the "photography cabin" with Sue Stoessel, Bennie Gregory and Hunter Daniel (in a previous mapping trip though):

You see, it is just a bottle of soda and some duct tape, you can DIY it!

Now you may wonder why we take these pictures :

- for science study and evaluation of the impact of the oil spill on the coast and the marsh lands.

- for legal purposes, so we have evidences of the impact of the oil spill at the court of justice ;)

I'm in love with this technique Gonzo Earth and Grassrootsmapping keep on improving, also because I really need it to assess the efficiency of the oil spill collecting robot I am working on : protei.org. Here we were testing to see how well we can sail the robot upwind with a long tail :

that's the robot I am prototyping this week :

If you want to help on the making of the protei robot, or do some aerial photography of the oil spill, get involved at LA Bucket Brigade, contact Shannon Dosemagen <shannon@labucketbrigade.org>, or Hunter Daniel <hunterdaniel@gmail.com> 901-550-7667 directly by phone to arrange a trip in the sun :)

TEDxBoston : the Gulf of Mexico Oil Spill

This is NOT an Official TED video, it is simply an archive of the TEDxBoston Adventure.

What academic light can two Boston College professors shed on the nation’s largest environmental disaster?
What lessons for oil extraction, transport, crisis prevention, and response can be drawn from this present calamity? Meanwhile, can a 2010 TED Fellow on the frontline in the Gulf contribute to the design of autonomous robots that collect oil?
Join Boston College Professors Noah Snyder of the Geology and Geophysics department and Zygmunt Plater of the Law School for an interactive briefing on the situation in the Gulf. Professor Snyder is the Director of BC's interdisciplinary Environmental Studies program. Professor Plater served on the State of Alaska Oil Spill Commission during the Exxon Valdez crisis; he has been involved with Alaskan efforts to assist Gulf communities in the aftermath of the BP Gulf blowout and attempts to draw systemic lessons for the future from the Exxon Valdez and the BP blowout. We also will be joined via Skype by Cesar Harada, a former MIT researcher in New Orleans. Ask critical questions about environmental science and law, as well as some of Harada’s other ambitions, from creating the International Ocean Station as an open-source architecture project to crowdsourcing environmental data on the web.

Thanks to John Werner and Grier Tumas.

Contemporary slavery

Before yesterday, 2010/07/21 with the folks of LA Bucket Brigade, we went on the "1811 Slave Revolt Tour" by Leon Waters of the Louisiana Museum of African American History.

I highly recommend this tour (original map on google maps) if you are around New Orelans, 20$/ person for half a day, worth the money. Tel +1 504 432 9901 | history.hidden@gmail.com. The tour took us walking in the steps of the slaves that rebelled in 1811 in Louisiana, marching on New Orleans for their freedom, shouting "freedom or death". This march also called the 1811 German Coast Uprising is the largest slave revolt in the United States and the one of the least known, due to an underlying revisionism according to Waters.

We were able to visit graveyards were black heroes of the civil war came back to build entire communities around churches. Back in 1811 the life of the slaves was cruel, exploited to death, working in the plantations, sexually abused, lodging in miserable huts, forced to manipulate toxic materials, exposed to mortal gases in the early industrial era. The cruelty black people were exposed was proportional to the wealth of their owners, often reflected in the surface of their lands and the magnificence of their master house.

Historical researches have permitted to locate accurately large slave cemeteries, now abandoned and invisible, buried under the sediments, especially since the area his used as a gigantic spillway.

The Louisiana Museum of African American History has been working for a long time to get access to make archeological study of the hidden cemetery. Permission to study this site of historical importance has been denied, and even the marking of the site with a public banner has not been allowed. History hidden.

In 1811 white landlords were forcing black slaves to manipulate fatal toxic, such as the one required in the fabrication of Indigo (pigment). Today, the swamps owned by the former slaves children has been bought by major energy companies at an unfair price to host multi-millions polluting facilities. The descents of the slaves still live on the "fence lines" of these industries. The inhabitants suffer severe health issues (cancers, asthma) and the fancy playgrounds built by corporations have no children playing.

La Bucket Brigade has been working since 10 years to support the local communities in front of merciless corporations which are stronger than the federal government itself. There is so much secrecy and lies, about the current DeepWater Horizon Oil Spill, we have been informed that several oiled beaches were just covered with sand, hiding oil instead of collecting it.

Today, most of BP cleaning staff on the beach is black american and BP does not allow them to wear respirators, to avoid "spreading hysteria". We do not have access to health reports of BP cleaners, many secretly report they are suffering, they are all under pressure and agreement of non-disclosure... When will the next rebellion happen?

Cruel chapters of history are being written today, strangely familiar.
