This robotic dolphin could replace captive ones, via Gizmodo
You don’t need to have seen documentaries like The Cove to feel uneasy about whales, sharks, and dolphins being held captive in tiny tanks at aquariums and theme parks. But instead of eliminating those experiences completely, which can help educate the public about these creatures, robots, like this self-contained swimming dolphin, could instead be the star attractions.
Theme parks like SeaWorld have always posed ethical concerns because, unlike zoos, the captive creatures are often trained and required to perform for visitors several times a day. And while zoos raise similar ethical concerns, there have been efforts to make outdoor exhibits larger so they can more closely resemble an animal’s natural habitat. Recreating the vast scale of the ocean just isn’t possible in a theme park where aquatic exhibits are competing for real estate with rides and other attractions.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
