About five years ago, experts from Harvardfor the first time the university introduced the world's first bee robot called RoboBee, which, as technology improved, was able to safely go through several upgrades, learning how to plan, sit on tree leaves and even swim. Equipping the device with a mechanism with soft actuators, RoboBee also acquired the ability to fly independently using artificial muscles.
A robot that can fly
According to news.harvard.edu, Robobee - the first microrobot in the world capable of flying controlled flights. Equipped with a special material that plays the likeness of soft muscles, the robot practically does not receive significant damage when it collides with walls or accidentally falls. At the same time, the possibility of a significant breakthrough in robotics using soft actuators has long been discussed by experts as a rather dubious idea due to some difficulties encountered in controlling the micro-camera.

In order to increase the chances of success withIn the operation of the apparatus, researchers from the United States modernized the production technology of a soft actuator driven by conventional electric energy. Having significantly improved the device by using dielectric elastomers, which are special soft materials with good insulating properties, researchers from Harvard obtained Robobee's effective work at a frequency of 500 Hertz, which is comparable with the necessary parameters for hard actuators.

One of the problems that occurs when creatinga new generation of robotic devices, it is considered strong fragility and instability of the microrobot during operation. In order to ensure effective use of soft artificial muscles by the robot, researchers at Harvard decided to use a lightweight frame, which provides, among other things, the ability to relatively easily fly into the air. The tested model with two wings showed its ability to successfully overcome obstacles and continue flying even after a collision with a similar device. This ability can help researchers improve flight technology and teach miniature robots to penetrate even the most limited space, making them indispensable assistants in search and rescue operations.
