A 15-year-old Canadian teen built a robot turtle, which could help scientists spot reef damage earlier and transform ecological threats underwater

A 15-year-old Canadian teenager developed a robotic turtle capable of sensing ecological hazards in water. This creation is unique because it involves both an existing species and a developing environmental issue. Specifically, the robotic turtle created by Evan Budz is able to sense signs of stress and damage to corals underwater.

On the surface, this creation may seem like entertainment. However, the concept behind it touches on an urgent problem in science. Nature Machine Intelligence highlights the need for new technology in order to facilitate reef monitoring on a large scale because of its vast coverage and expensive fieldwork. According to this publication, automated technologies may help researchers monitor changes in the area that cannot be observed by a human team.

Coral reefs all around the world face environmental hazards due to global warming, pollution, and deforestation. For this reason, researchers are trying to develop innovative technologies that will help monitor those environmental changes. Specifically, scientists believe that robots may assist conservationists in collecting information faster and more regularly than traditional divers would.


Significance of the turtle-shape structure

A turtle shape is not just a cosmetic choice in this case. Robots inspired by nature and real-life animals are used in marine technology more frequently nowadays because they offer more subtle movements in fragile environments. Coral reefs are sensitive ecosystems that contain tight spaces and require gentle movement. Large submarines can disrupt marine creatures and cause damage to the coral reefs' structure. It can be helpful to create a small turtle robot that moves around more gently.

According to Nature Index, today's coral reef science increasingly utilizes autonomous underwater vehicles, optical sensors, and artificial intelligence to monitor coral reef systems and track environmental changes. They reported in an article discussing automated monitoring of reef systems that future reef protection will largely rely on monitoring technologies.

Therefore, Budz's research is not merely a school experiment but rather a reflection of the current developments within this sphere.

It is increasingly difficult to protect coral reefs

For many years now, the scientific community has sounded the alarm regarding coral reefs’ vulnerability in light of the warming up of our oceans. Bleaching happens when corals release the algae responsible for sustaining life. A particularly bad case of bleaching leaves the reef in ruins for decades afterwards.

According to the National Oceanic and Atmospheric Administration, also referred to as NOAA, coral reefs provide homes for at least 25 percent of all marine species even though they cover less than one percent of the ocean floor. Hence, the significance of reef monitoring cannot be understated. Early detection of stress allows taking timely action and prioritizing certain parts of the reef.

The idea behind Budz’s turtle robot is precisely that. What matters is to recognize the signs of trouble before it is too late and not really to do anything about them right away.

A teenage inventor tackling an important issue

This kind of robot falls under an emerging category in which the two disciplines of engineering and environmental science meet. There are already attempts at using autonomous vehicles in the fields of coral research, fish stock assessment, and ocean mapping.

As far back as 2011, Professor Mark Patterson of the Department of Marine and Environmental Sciences at Northeastern University observed that there was a need to create autonomous underwater robots since humans simply cannot monitor marine ecosystems at the scale needed today.

Another reason why researchers are constantly looking for ways to develop efficient underwater robots is to make this process easier and cheaper than it is now. The creation of such a robot is another example of democratization of technology in the field of environment monitoring.

Why this project is important to the audience

To begin with, the robot looks attractive from a design standpoint. A machine resembling a turtle will evoke sympathy and understanding in the minds of ordinary people. This way, one will be able to easily imagine the turtle monitoring reefs for signs of damage.

In terms of environmental education, an object-oriented image of something complex can be helpful. This particular initiative is also indicative of trends in conservation. The observation of ecosystems is not restricted to scientists using notepads and boats anymore, with an ever-growing tendency for monitoring environmental changes through drones, sensors, cameras, and artificial intelligence tools.
