  • "Parasitic" robots are now riding turtles to get where they need to go. Dae-Gun Kim at the Korea Advanced Institute of Science and Technology in Daejeon and his colleagues glued small box-like robots to the backs of five red-eared slider turtles. The robots included a frame that stuck out in front of the turtle's head holding five red LEDs spaced 30 degrees apart, and a food-delivery tube. The robots had to ride their turtle through five checkpoints in a tank filled with water. The turtles were conditioned to associate a lit-up LED with food--so the robots 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.
