20140826 Test of Protei 011.1 at sea

Original post :

A few days ago, we had a great time testing Protei 011.1 at sea thanks to Alex Li, Helen Yau and David Biddlecombe. The boat was prepared by Guillaume Dupont, Jessica Louie, Cesar Harada, Bianca Cheng Costanzo and documented by Kwok Wah and Chris Butler.
The test was a success, no leak, very good manoeuvrability. Unfortunately there was no much wind.

Happy Wah

We also had some damage. We bent a boom in the MTR (train) and broke one mast when Protei 011.1 went under our big boat. So we are working on making a stronger mast, bigger diameter and full aluminium rod (instead of hollow).

A big thank you to Alex Li for letting us get on board of his boat for testing in beautiful Sai Kung, Hong Kong.

20140728 Protei Scoutbots Progress Report

20140728 Protei Progress Report

How can I answer a simple question such as “How is Protei doing?”. We have come a long way. From a small garage in New Orleans during the BP oil spill, through the storm in the Pacific ocean and now in Hong Kong since last year. It has been 4 years. We are finally about to deliver all our Kickstarter rewards, as we promised. We are turning the page and starting a new chapter of this great adventure with Open Technologies, to explore and protect the oceans, together. This report should give you a good overview of our current situation, future strategies and hopefully make you want to engage more with us, as a sponsor, investor, partner, buyer, community or team member.

This is a google doc, please ask questions and add comments on it to help us improve, thanks a lot.

Scoutbots & Protei core values published!

originally posted on

It’s a big step I feel. I just published our company licenses, documentation, core values, order of priorities and our people’s page. It is a long overdue and these documents will change but we are really growing as a company and myself as a leader. I am grateful to our supporting partner SOW Asia incubating i2i program because they have greatly contributed to formalise these documents that will help us grow.

Below is a video of Tony Hsieh, Founder and President at Zappos, explaining how they came about and what their core values mean.

Our values are a mix of The Maker’s bill of Rights, Zappos core values, the seven virtues of the bushido  and the scout rules and methods – which make total sense to me :D When talking to potential investors / sponsors, we had sent them hints about our values but now it’s on our website, “it is official” :)

Our licenses has actually been decided long ago when we published our first big report back in 2011. At the time we had been very much influenced by Arduino intellectual property setup and business model. We have decided to upgrade for the CERN Open Hardware license for that it looks like it is the most “mature” Open Hardware license we can find out there and that it is actively being updated.

The documentation has been one of the main problem in defining the standard of the young Open Hardware movement (first Open Hardware Summit was in 2010 in Queens NY). There have been a lot of discussions, but there is no set standard yet, more a recommandation list. We follow that trend even though at some point we would want to define a minimum of set required documents to qualify as an Open Hardware project.

The adventure continues!

What is a windtrain?

Original post on Scoutbots here.

Maybe you have heard through social media that we have been working on a new type of terrestrial sailing machine we call “Windtrain” – we also have now the domain. Now you must be wondering “how is this going to help the oceans?” – and you are right to ask. Well, let me explain : a few weeks ago, we were testing Protei “Rationale” in Hong Kong and we left the workshop with a good wind forecast. By the time we arrived, there was no more wind. Bummer. It happened a few times and I started to feel frustrated. So I thought it might be a clever idea to build a sail testing platform on wheel that I could use on the parking lot next to our workshop. Windtrain was born! I also realised that many people have a hard time understanding how Protei – the shape shifting sailing robot – works, because it is in the water ; while a land-based equivalent would be understood by a greater number of people. Also many things that we would learn from Windtrain can be transposed to Protei.

windtrain first test

Let’s face it, Windtrain Zero was not spectacularly mobile :) It moved a little bit but… not something to be hugely proud of :)

Followed a sleepless night : Windtrain “Mister T” was born, for that it is based not on an “+ frame” but on a “T frame”. And it sailed beautifully on Kam Sheung Road MTR parking lot.

That was too exciting to stop there, so I kept going!
For the next version, I decided to bet everything : build a giant Windtrain, 6m, still controlled by the same tiny servomotor : will it work? We had no idea, so we called it “Heads or tails” :) Guillaume Dupont helped me test this one at the Hong Kong Science Park.

To me, what is really beautiful about the Windtrain is that the huge machine is still controlled by a tiny servomotor that uses about the same energy than an iphone ringing.

We only had 24 hours before I would fly to Estonia and demo this new concept when we realised that transporting the Windtrain “Heads or tails” that is 6m long + , would be a problem – oops. So, in a situation of total emergency, we had to develop, build and pack Windtrain “Baltic”, which is the one at the very top of this post. Windtrain was presented for the first time publicly at TEDxTallinn with this slideshow commenting about the history of transportation.

So what’s next? We’ll keep developing the Windtrain until we have a first stable version that is easy to manufacture and ship. So everyone can buy, improve and share :) In other words, you will soon see the Windtrain in our shop and you will be able to buy it online :) We cannot say exactly when or how much it is going to cost but stay tuned :) Exciting !!!

Skype in the classroom : Develop Innovative Open Ocean Technology

Develop Innovative Open Ocean Technology - skype in the classroom

Next week I am going to be teaching a class on the theme of “Develop Innovative Open Ocean Technology” on skype, for free. You can attend, but please do let me know when you want it to happen here by voting your preferred time : The pool will be closed this friday nov 9th.

About this Skype lesson
In 2010, when the BP Oil Spill was pouring in the Gulf of Mexico, Cesar Harada left MIT and moved to the Gulf to develop an Open Source robot to clean up oil spill. From a friend’s garage he developed “Protei” the revolutionary shape-shifting sailing robot that would sail upwind pulling a long oil sorbent to clean up the oil slick. After a successful Kickstarter campaign the newly-assembled Protei team embarked on building Protei_006 in Rotterdam (NL), the largest shape shifting sailing robot to date. In 2013 CEO Harada and COO Gabriella Levine sailed around the world testing Protei technology and developing a business strategy for an innovation that has the potential to drastically lower the cost of surface exploration and cleaning the ocean with an open technology. Protei aims at manufacturing it’s first batch of commercial autonomous sailing robots by the end of 2013 from their newly built Hong Kong Headquarters with their manufacturing partner Seeedstudio in Shenzhen.

In this class, Harada would briefly explain Protei concept, history and future development and will invite you for questions. The themes that we would talk about are ocean robotics, open hardware for the environment, ethics of business for ocean healthy future.

The videos the participants should watch before the class are :
And imagine what a swarm of highly maneuverable robots could do for the oceans (as maneuverable as these flying quadrotors):

Participants should also read

The places are limited, so looking forward to see you there :)
For questions, you can join me here cesarminoruharada – knock knock : do not call during the class  :p

2013 Lamma Island Oil Spill needs more Research & Cleaning

On July 14th, my girlfriend and were hiking on Lamma Island (Hong Kong) for her birthday. I was told there had been a small oil spill recently, but I did not expect to see it when we arrived in Tung O Wan, Shek Pai Wan (22.196649, 114.139827).

“June 21, a 10m x 15m slick was reported in waters off Tung O Wan, and a 100m x 15m slick was seen on Tung O Wan beach. The department cleaned small oil patches off Tung O Wan on June 22 and 23, and will send samples of the oil to the Government Laboratory for analysis.”

We made this video with our mobile phone that day, thanks to Nadege Nguyen.

Oil Spill at Shek Pai Wan, Lamma Island
That’s how we saw the beach on the July 14th 2013. All the black slug you see on the rocks is oil.

I guess that’s the oil as it was reaching shore a fews days after June 21st 2013 (Aerial photography).

That was before the oil spill. It would be good to get back to this state.

Proposal for further Research & Cleaning

Shek Pai wan site needs more research and more cleaning.

  1. Biological analysis. Sampling crabs, fishes, turtles, shells and study their respiratory, digestive, endocrine and reproductive systems. 
  2. Aerial Photography & Mapping with visible and infrared spectrum.
  3. Underwater photography and mapping with visible and infrared spectrum
  4. Water sample Spectrography to detect traces of oil  (and perhaps other chemicals) in water

All research would be done using Open Source technology and the findings published as we go.

I am looking for Hong Kong residents to collaborate, please get in touch :

Open Hardware for the Environment Questions


Thanks to Andrea Grover, I got these highly relevant questions about Open Hardware for the Environment from Hiroyuki Hamada. With his permission, I am transferring these questions here on my blog, to perhaps integrate the FAQ of Protei new website.


>> Have you met any resistance from governmental organizations or industry people for not conforming to the traditional business model or simply be seen as a threat?
I think we have been too small to be seen as a threat to anyone for now, but we hope that as we grow, this will not happen. We really want to serve government, industry, academia and residents (environmental activists) as a neutral technology platform for science and environmental remediation. Our technology is very new, in comparison flying drones have attracted much more serious and deserved criticism, it is a matter of time I guess. Any technology can be used for malicious ends, we need to work on best practice and I personally will not support military applications of our technology.
Our business model is based on an Ethical Order of Priority that puts the environment first. This is the shift that our civilisations need to take if they are interested to continue existing in the future. Joi Ito puts it very well here :

One hundred years from now, the role of science and technology will be about becoming part of nature rather than trying to control it.

So much of science and technology has been about pursuing efficiency, scale and “exponential growth” at the expense of our environment and our resources. We have rewarded those who invent technologies that control our triumph over nature in some way. This is clearly not sustainable.

We must understand that we live in a complex system where everything is interrelated and interdependent and that everything we design impacts a larger system.

My dream is that 100 years from now, we will be learning from nature, integrating with nature and using science and technology to bring nature into our lives to make human beings and our artifacts not only zero impact but a positive impact to the natural system that we live in.

I agree with this statement, and I believe is that this way of thinking should not be postponed to a hundred years from now, but put in practice immediately to re-think our philosophical, economic, industrial and social models. I am lucky enough to start a project from a blank slate and incorporate these into my group strategy, vision and daily operations.

>> How do you enforce the conditions for the open hardware partnership? Patent issues? And most importantly, how do you make sure that the ethical concerns–the environmental concerns–to be the central to the projects? Have there been any legal cases involving open hardware?
Any technological device that’s complex enough, comes with a user agreement and some sort of disclaimer limiting the liability from the manufacturer in case of misuse of the technology / accident incurred. If it was expensive enough it might even come with a warranty. If the technology is recent and occupies a significant market segment, it is likely that the technology will be licensed / patented in order to guarantee the industrial an exclusivity on the intellectual property, the manufacturing, distribution, branding and marketing of a technology. Each person in this traditional chain protects their interests, monopoly, maximise their own profit with a reduced transparency.

It is in the interest of everyone in the Open Hardware community (makers and users are the same people) that the technologies progresses fast. That’s even more clean when it is to address environmental issues. When we publish our work, we publish it as alpha or beta on the public web under an open licence.   So far we have been using :

We are in the process of developing our own “flavour” of Open Hardware license that we are calling Open Hardware H2O, that will be maintained by the non Profit organisation Open-H2O specifically for aquatic applications, similarly to how the CERN developed their own “Open Hardware CERN” license.
To date and in my knowledge, the Open Hardware license that we are using has not yet been challenged at the court (it is only 2 years old license). Of course, we do not want to see any Open Hardware company being abused but we are looking for our license to be validated through winning a litigation, making a case.

The licensing of the work cannot enforce that the technology will be used for environmental good ; as it is an open source technology, anyone can use it for whatever they want, we do not want to declare any use of our technology illegal, the user is responsible. In our company, we have decided to make decisions according to the ethical principles mentioned above, that means that : to economic growth we will prioritise environmental growth, social growth and technological growth. We found that not only people or companies can work like that, but a new generation of stock exchange such as “Impact Investment Exchange” value the environment and social good as well as economic trade . This is not a purely an uninterested ideological statement -as we do need to make money to operate- it is also going with the assumption that environmental resources are more precious than economic resources : “When the Last Tree Is Cut Down, the Last Fish Eaten, and the Last Stream Poisoned, You Will Realize That You Cannot Eat Money” (I found it hard to find a reliable source to quote, I apologize). We believe that technology is to serve the environment, not to dominate it, and that on the long term, we will see greater economic returns as we protect and promote precious “environmental assets” ; this goes without mentioning water wars, Environmental migration and other impacting socio-economic events …


>> I see that the successful operations of open hardware depends on openness, equal rights and fairness. There might be additional challenges if the market/operation to be global because of the differences in governmental regulations or restrictions possibly imposed by corporate based international treaties (NAFTA, upcoming TPP and so on). Has there been any global initiatives to enforce and protect the basic rules of open hardware? 
I believe in equal opportunities, but I personally believe in meritocracy to run a community and a company – to me that’s fairness, and that’s encouraging efficiency to serve the purpose of the company : explore and protect the Environment.
There will be challenges inherent to the space we are evolving in (international and national waters) and the questions of liability of sailing drones is a relatively new subject for everyone, as autonomous journeying just found a new record a few days ago. I must admit that we do not have the answer to this today. The “Open Hardware H2O” license version 0.1 that we are working on is meant to draft what would be the inventor, manufacturer, ship-owner, user/operator responsibility in respect to all the NAFTA, TPP, Governmental regulations and treaties. As our organisation grows and we get more funding, we will be able to support more lawyer’s time and upgrade this license from Version 0.1 to 0.2 etc.

>> Are the big industries catching up to incorporate the open hardware? 
Big industry players are starting to understand that Open Innovation is where future big money is, with the rise of the Prosumer, the long tail and other economic paradigm born in recent years with the internet, mobile technologies and globalisation. The question is “can they adapt?”, “can they re-invent themselves?”, or will they collapse under their own weight as most empire do? We are in discussion with several large companies, because they are interested to understand how we innovate so fast, and how we thrive ignoring boundaries between governments, industries, academia and residents -namely- the entire market. Think about automotive Industry that may be one day taken over by groups such as wikispeed, think about agriculture with Open Ecology, and us for ocean technologies.
One of the most emblematic Open Hardware technology is Arduino and you can now find it in every RadioShack. In 2010 Lady Ada and P Torrone presented “Million dollar baby – Businesses designing and selling open source hardware, making millions“, and that was 2010, now we are talking about hundreds of Open Hardware projects and businesses.

Open source hardware $1m and beyond – foo camp east 2010 from adafruit industries on Vimeo.

At the occasion of Iran Army intercepting a US drone, Chris Anderson of 3D Robotics made fascinating comments of how the US Army is interested to tap into Open Hardware to accelerate technology development. You would be surprised how many open source technologies are used for national security and intelligence.

I personally believe that the Open Hardware movement is at the heart of the Next Industrial Revolution. What I am interested in is : how can we can make sure that this industrial revolution does not perpetuate even more harm to the environment than the previous one did, hence my extreme interest in the “Open Hardware for the Environment”.
I am now :

  • writing my PhD Thesis about the topic
  • starting a business of ocean robotics based on these premises, Protei INC.
  • contributing to a non-profit that develops such technologies, Open-H2O.

This is an unchartered territory and we need to make our own way through the unknown. It is certainly exciting, the stakes are high with huge environmental challenges, and we will make many mistakes, stumble and get back up, each of us contributing an un-recognisably microscopic part to the transformation of our human culture. But what I love about this movement is how many shoulders one can find, how many helping hands are joining this effort, how many friendships are built. It is a technological adventure, but it is also a philosophical one, a financial one, an environmental one. Yes, one day big industries will capture the spirit of Open Hardware and market it, some of it will be controlled by us, some not, and some of us will continue to explore always further, dreaming and fighting for environmental justice.
