The first cyber-roach goes back to 1997, when Shimoyama Isao of Tokyo University sent electrical signals to a cockroach’s antennae, causing it to turn either left or right depending on which antenna was stimulated. Others have built on this approach by recruiting extra sense organs, such as the rear-facing cerci. They have also begun fitting the insects with instrument packs that might let them do a useful job: searching collapsed buildings for survivors. What is your take on using robots in this course?
