Nearly indistinguishable from their real-life counterparts,
newly-developed robotic bottlenose dolphins could save hundreds of
dolphins from the cruelty of captivity.
Working with America’s top animatronics experts, New Zealand-based
Edge Innovations hopes to help people swim with “dolphins” without
stealing these majestic creatures from the wild or breeding them in
captivity.
“The marine park industry has had falling revenues for over a decade
due to ethical concerns and the cost of live animals, yet the public
hunger to learn about and experience these animals is still as
strong as ever,” California-based designer Roger Holzberg told The
Guardian. “We believe that it’s time to reimagine this industry and
that this approach can be more humane, and more profitable at the
same time.”
The remote-controlled, 600-pound prototype bears an uncanny
resemblance to a live dolphin and convincingly interacts with
humans. Test audiences couldn’t tell the difference between the
robot and the real animal, according to developer and reality gaming
expert Melanie Langlotz, who came up with the idea of using
animatronics in aquariums after a Chinese company asked her to
design an aquarium containing live animals. Uncomfortable with
animal captivity, Langlotz and her business partner, Li Wang,
brainstormed for alternatives.
The robotic dolphins last longer than live dolphins and cost far
less to upkeep, making it an appealing prospect to aquariums
currently losing revenue. Red Star Macalline Group sponsored the
first development phase and is considering implementing the robotic
dolphins into its aquariums in China. Other Chinese companies have
expressed an interest in the faux dolphins as a potential way to
accommodate the country’s marine park industry amid the
newly-imposed nationwide ban on the wildlife trade, RNZ reported.
As animal captivity falls increasingly out of favor, the development
team is focusing on ways to mass-produce the robotic dolphins and is
looking to replicate other creatures, such as sharks and whales, in
hopes of coming one step closer to upending the zoo and aquarium
industries.
