The new technology guarantees robots a microcontroller with Bluetooth, radio, sense, does not come with a battery and is only 12cm long
Researchers at the renowned University of Washington present an impressive technological innovation: flying robots that do not require batteries and use an origami-inspired technique to change their shape during flight. These small devices, approximately 12 cm long and a few grams in weight, although compact, are packed with cutting-edge technology, according to the R7 website.
They are equipped with a programmable microcontroller, Bluetooth radio communication, solar energy capture circuit, pressure sensor to estimate altitude and a temperature sensor – all contained in an incredibly small structure. However, these robots cannot initiate flight on their own, depending on drones or other high-altitude objects to be launched and the wind to move.
Inspired by nature: flying robot technology with origami design
When it is time to begin the descent, each microdevice receives a signal via Bluetooth, containing timing and altitude information. At this point, they resort to a technique origami fold called Miura-ori, which is a specific geometric pattern. This allows the robots to reduce their size, helping them quickly dive towards the ground.

Scientists found inspiration for this technology design in the way leaves fall from trees. “We combined Miura-ori folding, inspired by geometric patterns found in leaves, with energy harvesting and small actuators to allow our flyers to mimic the flight of different types of leaves through the air,” explained Vikram Iyer, assistant professor at Paul G School Allen of Computer Science and Engineering at the University of Washington.
Surprisingly, these tiny devices have the ability to travel more than 100 meters in a straight line and withstand drops from heights of approximately 40 meters without sustaining damage. But his skills don't stop there.
Versatile Applications for Battery-Free Flying Robots
Microflyers are not just a marvel of technology, they also have practical applications. They can be used to collect crucial environmental data such as temperature, humidity and other conditions. This data collection capability makes these robots particularly useful in a number of areas, such as environmental monitoring and scientific research.
However, scientists also recognize the need to consider the ethical implications of this technology that It is not necessary of emerging battery. They express concern that in the future, these flying robots could be used for less noble purposes, such as espionage or harmful activities.
The future of technology-free flying robots: challenges and opportunities
While the technology behind these battery-free flying robots is impressive, it also raises ethical and safety challenges. Responsible development and appropriate regulation are essential to ensure that these innovations are used in ways that are beneficial to society.
As research advances and new applications are discovered, the potential of these wireless flying robots drums inspired in origami is vast. They can revolutionize the way we collect data in challenging and inaccessible environments, opening doors to new discoveries and scientific advances.
However, the responsibility lies with society and researchers to ensure that these battery-free technologies are used for the common good, balancing innovation and ethics for a better future.
