A yellow robotic named “ECHO” helps scientists in Antarctica to maintain tabs on among the continent’s penguin residents.
At Antarctica‘s Atka Bay, researchers on the Woods Gap Oceanographic Establishment (WHOI) are monitoring a colony of about 20,000 emperor penguins (Aptenodytes forsteri) with the assistance of a hybrid rover that is partly autonomous and partly remote-controlled.
The four-wheeled robotic is a part of a 30-year-long WHOI program that launched in 2017, known as “Monitor the well being of the Antarctic marine ecosystems utilizing the emperor penguin as a sentinel,” or MARE for brief. The MARE challenge screens emperor penguins and makes use of them as indicators of total ecosystem well being in Antarctica. The challenge paperwork how effectively the penguins adapt to local weather change and its affect on the abundance and distribution of the fish they eat, WHOI representatives mentioned in a press release
ECHO’s objective is to take away any human presence from penguin surveys, as counting and cataloging hundreds of birds is time-consuming and might stress the animals, in line with WHOI.

To make ECHO the proper penguin monitoring car, scientists outfitted the 3-foot-tall (0.9 meter) rover with lidar (gentle detection and ranging) and GPS know-how to navigate autonomously. ECHO carries sensors that assist researchers monitor the penguin colony’s numbers and observe people’ motion and habits.
For instance, a radio frequency identification (RFID) antenna scans tiny RFID tags that WHOI researchers implanted in penguin chicks when the kids had been about 5 months outdated. For the reason that MARE challenge started, researchers have tagged round 300 penguin chicks annually, in line with WHOI. As soon as ECHO is in vary of a penguin’s RFID tag — about 34 inches (86 centimeters) away — the robotic can retrieve details about total health and breeding standing, in addition to oceanographic knowledge from when the penguin was within the sea. A 360-degree digital camera allows scientists to establish particular person penguins that ECHO encounters, and GPS knowledge reveals the extent of the penguins’ distribution and their habitat hotspots.
Researchers at WHOI modified ECHO from a Husky robotic equipment created by the robot-manufacturing firm Clearpath Robotics. The robotics firm awarded WHOI the Husky equipment in 2020, Clearpath representatives mentioned in a assertion. Previous to ECHO, MARES challenge knowledge was collected utilizing handheld RFID scanners and human observations.
The information ECHO collects is transmitted over WI-FI to the Single Penguin Commentary and Monitoring Observatory (SPOT) analysis middle. Situated close to the German Antarctic analysis base Neumayer Station III, SPOT may also perform penguin observations, utilizing 16 high-resolution cameras able to pinpointing particular person penguins inside the colony, in line with WHOI.
Emperor penguins haven’t any pure predators in Antarctica, so they’re good examine topics for scientists trying to perceive how animals are affected by ecosystem fluctuations attributable to local weather change.
Nevertheless, the birds’ survival in a warming world is unsure. A examine printed in 2021 within the journal World Change Biology reported that the speedy decline of Antarctica’s ice might trigger that emperor penguins to develop into “quasi-extinct” by 2100 — which means that though there may nonetheless be particular person penguins alive, the species as an entire could be doomed to extinction.
“Biodiversity within the Southern Ocean is so small, in comparison with extra temperate areas of the world, that dropping any species there’s sort of devastating,” Daniel Zitterbart, an affiliate scientist at WHOI, informed CNN.
WHOI researchers plan to increase ECHO’s knowledge assortment efforts to incorporate the penguins’ foraging and reproductive behaviors, in addition to what occurs inside a penguin huddle — a social habits wherein the colony huddles collectively to remain heat and preserve power. To infiltrate the penguin huddle, researchers plan to place ECHO inside a 3D-printed duplicate of a block of ice. ECHO and its icy disguise would then be positioned within the path of a forming huddle, which generally occurs in winter after the breeding season, whereas the male birds are brooding their eggs. This disguise would allow ECHO to gather penguin knowledge whereas the birds are in shut contact with one another, in line with WHOI.
