Researchers from top universities—MIT, Harvard, and City University of Hong Kong—have created insect-like drones. These tiny robots, weighing just about 0.6 grams, look and act like insects with their agile wings. They are powered by a soft actuator made of thin rubber cylinders in carbon nanotubes. When you apply voltage to these nanotubes, these insect-like drones get the capacity to fly. Unlike the previous drones, these can work in tight spaces and withstand collisions. Researchers hope that these robots can help humans in pollination or assist in search and rescue missions in the future. Watch this MIT video to learn more.
