MIT scientists are developing robotic insects that could revolutionize pollination by boosting crop yields without harming the environment.

Previous designs lacked endurance, speed, and agility, but a new version detailed in Science Robotics on Jan. 15 flies 100 times longer, is lighter, and has improved wing flexibility.

Unlike earlier eight-wing models, the new design features four single-wing units, enhancing lift and stability while allowing room for batteries, Live Science has reported.

Researchers aim to further refine the robots by integrating sensors and computing capabilities within five years.
