Keeping your robot invasions under control.

September 28, 2015 Andrew Thaler

It’s been a big week for papers here at Southern Fried Science. This morning, Amy, myself, William (of Bomai Cruz fame), and Dominik and Erika of OpenROV published our guidelines on minimizing the potential for microROVs to act as invasive species vectors in Tropical Conservation Science. The abstract: Remotely operated vehicles (ROVs) present a potential risk … Read More “Keeping your robot invasions under control.” »

Ocean Kickstarter of the Month: The OpenROV Trident

The future of ocean exploration is here.

OpenROV Trident – An Underwater Drone for Everyone by OpenROV

I’ve been watching, exploring, and working with the folks at OpenROV since their last Kickstarter, way back in 2012. Today they announce the launch of Trident, the next generation underwater vehicle, and one of the most capable microROVs that I’ve ever seen. I had the rare pleasure to join them in Lake Tahoe this May to test fly one of the earliest prototypes, and it surpassed all of my expectations.

You don’t need to hear me sing the praises of one of the most important emergent technologies in marine science and conservation. The rise of affordable, capable, portable underwater robots will fundamentally change the way we think about exploring the ocean and monitoring ocean health.

Onward to the Ocean Kickstarter criteria!

1. Is it sound, reasonable, and informed by science? You bet. OpenROV have been building underwater vehicles for upwards of four years. I use their robots in my research and education programs. The first peer-reviewed publication using OpenROV as a research platform will be coming out at the end of the month.

How to NOT get ahead in advertising – what many conservation NGOs are doing wrong

This year’s International Congress for Conservation Biology had a special double symposium on conservation marketing. What is conservation marketing I hear you ask? Well it’s using the tried and tested techniques from the advertising field, behind which there is a significant amount of research, to increase public awareness and especially change public behavior to aid conservation. Conservation marketing is already being used by several NGOs and initiatives – RARE for example. The Society for Conservation Biology has recently set up a working group for Conservation Marketing and Engagement* as it’s believed that this technique could help highlight many endangered species and highlight important conservation issues.

In this symposium myself and several colleagues had a presentation on why the advertising campaigns of conservation NGOs are doing things wrong – specifically these campaigns are often geared towards fundraising, telling members and especially donors what a great job they’re doing, launching surveys or petitions that do little to help conservation, oh and more fund- raising. The general public has a dire understanding of the need for biodiversity conservation or endangered species, and instead of increasing awareness and getting the public to change their behavior to act in a more pro-conservation manner, NGOs are instead concentrating on …hey did I mention fund-raising?!

As the result of many requests for copies of the presentation slides, I’ve decided to make them available for Southern Fried Science. Most of the slides are self explanatory. Feel free to copy and steal memes you like and count up the number of geeky references ….

A 3D-printable, drone and ROV-mountable, water sampler

The Niskin bottle, a seemingly simple tube designed to take water samples at discrete depths, is one of the most important tools of oceanography. Coupled with a CTD, an array of Niskin bottles fit into the rosette, a Voltron-esque amalgamation of everything an oceanographer needs to profile the ocean. Niskin bottles are neither cheap nor particularly easy to use. A commercial rosette requires a decent-sized winch to launch and recover, which means you need a vessel and a crew to deploy. For Rogue Ecologist and citizen scientists, getting a high-quality, discrete water sample is a perpetual challenge. With tools like the OpenROV and the soon-to-be-completed EcoDrone, I wanted a Niskin bottle that was light weight and capable of being mounted on both underwater robots and quadcopters with ease.

Until now.

After a few months of brainstorming and planning, I sat down this Friday and began building a 3D printable Niskin bottle that could be hand deployed or mounted on an OpenROV or drone. While this version is designed around a 1.25 inch acrylic tube, the trigger mechanism can be expanded to fit any size pipe. The trigger is driven by a waterproof servo developed by the good folks over at OpenROV. Everything else can either be purchased off-the-shelf or printed on you home 3D printer. Later this month, I’ll be taking my prototypes out on the RV Blue Heron for field testing in Lake Superior.

Print your own Mighty Megalodon Tooth for #SharkWeek (or #JacquesWeek)

Carcharocles megalodon is the largest shark that ever lived. It roamed the oceans from 15 to 2.5 million years ago. Its teeth can be found at fossil beds around the world, but especially in Yorktown and Pungo River formations in the coastal Eastern United States. Megalodon teeth are incredibly useful teaching tools, allowing educators to convey just how massive these animals were and open up discussions about evolution, extinction, and ecology while instilling a sense of wonder.

Now you can print your own piece of prehistory with this 3D printable Megalodon tooth!
