Ocean Alliance, like the city of Gloucester, Massachusetts, has its origins in the bounty and fauna of the sea. Headquartered in the historic Tarr and Wonson Paint Factory, Ocean Alliance, Inc. is a 501(c)(3) not-for-profit organization that was founded in 1971 by renowned biologist Dr. Roger Payne. Ocean Alliance strives to increase public awareness of the importance of whale and ocean health through research and public education. Led by Dr. Payne, CEO Dr. Iain Kerr , Ocean Alliance works with scientific partners to collect a broad spectrum of data on whales and ocean life. Ocean Alliance uses this data to advise educators, policy makers, and the general public on wise stewardship of the oceans to mitigate pollution, prevent the collapse of marine mammal populations, and promote ocean and human health.
Innovation In Conservation
CEO Dr. Iain Kerr has spent years researching whales, and explained that the best way to understand the ocean and its inhabitants is through biological data. In the past, the only approach to attain physical samples from whales was through a biopsy crossbow. This method provided valuable specimens, but proved to be a large undertaking. Dr. Iain Kerr explained,
“It seemed to me that there had to be an easier way to do this. Having been a hobbyist and a Maker for most of my life, and in watching the direction in which the hobbyist drone industry was going, I realized that there was a real opportunity to use drones to benefit whales and humanity.”
Dr. Kerr’s overall goal was to develop a research drone that could be used to collect non-invasive biological and photographic data from marine and terrestrial mammals. Using the collected samples of DNA, viruses, bacteria, stress and pregnancy hormones from whale blows, researchers could gather data to better understand whales, the oceans, and humanity’s effect on them in a benign manner. The team at Ocean Alliance believed that the drone design should be easily replicable and scalable, so that it could be adopted as a research tool around the globe. Using their design skills, Ocean Alliance created the first SnotBot.
What Is SnotBot?
SnotBots are custom-built drones created in partnership between Ocean Alliance and students from Olin College of Engineering. Guided by a remote driver, they hover in the air above a surfacing whale and collect the mist (blow) exhaled from its lungs on petri dishes. SnotBot then returns that “snot” sample back to researchers a significant distance away. This non-invasive technique not only collects substantial physical data from each specimen, but also leaves the whales undisturbed, allowing for a more accurate biological picture of the animals.
With over a dozen iterations of SnotBot, the designs evolved with the team’s better understanding of the machine capacity and payloads. The more they learned, the more they were able to push their designs and plans. With a natural hobbyist inclination to make, break and test things, Dr. Kerr believed in 3D printing as a tool to help further their ideas.
“I like to think of Ocean Alliance as an ocean innovator. I sometimes joke with my friends and say we’re not on the cutting edge; we’re on the bleeding edge. It’s tough to be an innovator. And often it’s tough to express an idea, or realize an idea, and test an idea. It can be very expensive. And this is where I think 3D printing is changing the world.”
Using 3D Printing To Advance The Design Process
January of 2015, CAPINC donated a MakerBot Replicator Mini 3D printer to Ocean Alliance to help further their SnotBot and robotics designs. The addition of the 3D printer has allowed Ocean Alliance to brainstorm multiple iterations of designs, enabling them to test their ideas in the field.
“This is where a company like CAPINC comes in because you can’t go down to Home Depot and say I need something to attach a FLIR camera to a drone that is light weight, adaptable, and adjustable. So the capacity for us to even build prototypes of what we think we need, or actually build the real thing, is very exciting.”
The MakerBot Replicator Mini is an entry-level 3D printer, ideal for new users interested in 3D printing, with minimal investment required. Dr. Kerr and his team have enjoyed having an in-house 3D printer.
“The unit that we have, that CAPINC has been supporting us with, has been a MakerBot, which, I must say, has been a lot of fun. And I think as an entry-level machine it’s worked very well for us. I will admit we’ve done our prototyping with the MakerBot and then we’ve gone to a next-level machine to do the final products.”
One of the projects 3D printing was heavily used in was designing the SnotShot. The SnotShot was created by Olin students to simulate various whale blowholes & blow patterns, allowing Ocean Alliance to test the different types of blows they might encounter with the SnotBot. This gave the team a better understanding of how to capture the most snot possible, before they even set sail on the open ocean. By 3D printing simulated blowholes for different whale species, they were able to test their SnotBot designs and make updates, saving them valuable time on their expeditions & avoiding prototype testing over live animals.
Along with their ocean and whale research, Ocean Alliance has spearheaded the development of an on-site robotics program. The Applied Robotics Club meets every Wednesday evening, providing an opportunity for people in the community young and old, to learn and explore anything from coding to design & construction, giving them to get hands-on experiential learning. Dr. Kerr has not only enjoyed the MakerBot 3D printer for SnotBot prototyping, but with the robotics club.
“The 3D printer has been invaluable! Not only in building unique parts that we need, and silly things that we might not need, but were fun to do, it has also helped us develop our thought and design process. It also encouraged both students and staff to explore ideas of building components that otherwise would almost be unimaginable.”
Since it’s first iteration, the SnotBot has been thoroughly tested and went on its first expedition this past fall in Peninsular Valdez, Patagonia. Ocean Alliance chose this location due to its enormous biodiversity. Since the 1970’s, they have been studying in Patagonia, with this last expedition being a great success.
“We have just completed the first successful SnotBot expedition to Patagonia. We have proved the viability of these drones as useful and adaptable research tools. In the course of the next year we plan to run a minimum of two more expeditions, one to the Sea of Cortez and one to Frederick Sound, Alaska, to build up our data sets, get as many flights over whales and work with as many whale species as our budget will allow.”
These future locations were specifically chosen based on the species that frequent the habitat and drawing from the experience of Ocean Alliance’s previous research expeditions.
The Future Of SnotBot
Formulating innovative and new ideas like the SnotBot takes brainpower and a determination to try multiple iterations. Traditional manufacturing methods cost extensive time and money, two things that are precious to not-for-profit organizations like Ocean Alliance. Luckily, 3D printing breaks down manufacturing barriers by allowing intricate designs to be built in-house for a substantially lower cost. CAPINC is a proud sponsor of Ocean Alliance and their 3D printing needs.
The future is big for SnotBot and its upcoming designs. With the next two expeditions already funded through their Kickstarter campaign, Ocean Alliance is still in need of donors to help create future SnotBot iterations for new data sets.
