Researchers mounted a “parasitic robot” on the carapace of a turtle. The robot is able to guide the turtle along specific paths by using LED lights and food rewards.
The South Korean team, led by Professor Phill-Seung Lee, head of KAIST’s Computational Mechanics and Structural Systems lab, designed their parasitic robot to physically attach to its host animal and use a combination of stimuli and rewards to produce specific behaviors.
They chose a turtle in part due to its inherent capabilities: It’s amphibious, has good eyesight and a long term memory, and comes equipped with a convenient shell, ideal for mounting parasitic hardware. Also, it’s slow enough that it was easy for the researchers to observe and control.
