IT之家 3 月 31 日消息，據美國加州大學伯克利分校官方媒體消息，該校研發團隊成功開發出了世界最小的可控制飛行的無線機器人，該機器人翼展僅 9.4mm，重量僅有 21mg。

IT Home learned that the miniature robot is not equipped with a battery, but has two built-in miniature magnets.Under the action of an external magnetic field, the magnet drives the fan blades to operate, which provides lift for the robot。 By adjusting the strength of the magnetic field, the researchers were able to precisely control the robot's flight trajectory.

However, the microrobot is not equipped with position/trajectory sensors, so it can only fly passively, and it is not possible to adjust the movement route in real time, and sudden changes in the external environment such as strong winds may cause the course to deviate.

The R&D team saidThe robot was developed inspired by the way bees moveIn the future, more complete flying wireless robots are expected to be used in scenarios such as microchannel detection and even plant pollination.
