"As hard as we’re trying, it’s going to be a very long time before we’re able to build a robotic insect that’s anywhere near as capable or versatile as a real one."

spectrum: So for now, we rely on a cybernetics approach to get real insects to do our bidding instead. By Evan Ackerman

'Over the past several years researchers have managed to steer large insects using electrical implants, a sort of brute-force method with limited real-world usefulness.

'Now engineers at Cambridge, Mass.,-based R&D company Draper are hoping to overcome those limitations by creating a cybernetic dragonfly that combines “miniaturized navigation, synthetic biology, and neurotechnology.” To steer the dragonflies, the Draper engineers are developing a way of genetically modifying the nervous system of the insects so they can respond to pulses of light. Once they get it to work, this approach, known as optogenetic stimulation, could enable dragonflies to carry payloads or conduct surveillance, or even help honey bees become better pollinators.'
