A world first: A robot able to “hear” through the ear of a locust

EurekAlert  March 2, 2021 During hundreds of millions of years of evolution, insects have evolved some of the most efficient and robust sensing organs, often far more sensitive than their man-made equivalents. Researchers in Israel integrated a locust tympanic ear with a robotic platform using hybrid bio-technological approach. Using an Ear-on-a-Chip method, they created a long-lasting miniature sensory device that operates as part of a bio-hybrid robot. The neural signals recorded from the ear in response to sound pulses, are processed and used to control the robot’s motion. This work is a proof of concept, demonstrating the use of biological […]
