Small flying devices that can change their movement in the air using an origami folding technique could revolutionize micro-sized flying robots. Researchers at the University of Washington have developed these robots that use the Miura-ori origami fold to transition between different flight states. The robots are thrown from the drone and land on the ground after walking through the air. This unique folding technique allows the robots to mimic different types of leaf movements, ensuring stability during landing.
The microplanes weigh about 400 milligrams and can travel the length of a football field when dropped from 40 meters in a light breeze. They feature essential technologies, including a built-in batteryless actuator, a solar-harvesting circuit, and a programmable microcontroller. These devices may also have built-in sensors to monitor environmental conditions such as temperature and humidity during flight.
In tests, the microplanes demonstrated the ability to change shape in mid-air, going from a falling position to a falling position in just 25 milliseconds. They wirelessly transmitted data up to 60 meters away, demonstrating their capabilities.
While current microfliers can only go in one direction, future designs will have the ability to go in both directions. This will allow you to land more accurately in choppy wind conditions.
This research opens up new opportunities for micro-sized flying robots using environmental monitoring and surveillance. The energy efficiency and innovative design of these robots show promise for the future of aerial robotics.
