Imagine a robot so small that it fits in the palm of your hand, resembling a bee. Researchers at the University of California, Berkeley, have developed a tiny flying robot that measures just 1 centimeter in diameter and weighs only 21 milligrams. This innovative creation is designed to mimic the flying and navigation abilities of bees, making it useful for tasks like search and rescue operations. The robot operates wirelessly, using a magnetic field to control its movements, allowing it to fly and change direction.

The robot's design includes two small magnets that enable it to take flight by responding to the magnetic field. While it can navigate towards specific targets, it currently lacks the ability to perform active maneuvers, which means it can be easily affected by sudden changes in its environment. However, future versions of this robot may incorporate active controls to enhance its flying capabilities, potentially allowing it to adjust its altitude and position in real-time.

In addition to the bee-like robot, researchers are also experimenting with a cockroach-inspired robot that can crawl on the ground. These tiny robots could work together in swarms to accomplish complex tasks that are challenging for individual robots. As technology continues to advance, the possibilities for these miniature robots are exciting and could lead to significant breakthroughs in various fields.
