Researchers at the Korea Advanced Institute of Science and Technology attached small robots to the back of turtles and enabled the machine to steer the animal by delivering it snacks. Eventually, they hope to use similar systems to control fish and birds. The technology could lead to parasitic robot/animal "teams" for surveillance, exploration, and disaster response. From New Scientist:
The robots comprised a processor, a frame that stuck out in front of the turtle’s head holding five red LEDs spaced apart, and a food-ejecting tube. They then had to ride their turtle through five checkpoints in a tank filled with water...
The turtles were first conditioned to associate a lit-up LED with food. The robot then simply guided it using the LEDs and fed it snacks as a reward for going in the right direction. Using this process, five robot-turtle pairs successfully completed the course, and each sped up with practice.

Archaeologists uncovered the skeleton of this neolithic dog more than a century ago in a 5,000 year old tomb on on the island of Mainland, Orkney, Scotland. Now, forensic scientists and artists have reconstructed the animal’s face. According to Historic Environment Scotland researcher Steve Farrar, this dog and 23 others found in the “Cuween Hill […]
Marvin Hajos, 75, of Gainesville, Florida, fell in his backyard and was then attacked by his pet cassowary, a giant bird from ratite group that also includes emus and ostriches. Native to northeastern Australia and tropical forests of New Guinea, cassowaries have three-toed feet with long, sharp claws. From CNN: The Florida Fish and Wildlife […]
From Deep Look: The quills of North American porcupines have microscopic backward-facing barbs on the tips. Those barbs make the quills slide in easy but very difficult to remove. Researchers at Harvard are looking to porcupine quills for inspiration in designing a new type of surgical staple that would also use tiny barbs to keep […]
