A new flying robot inspired by insects
September 15, 2018
A new creepy flying robot, created by TU Delft specialists from the Micro Air Vehicle Laboratory (MAVLab), is presented in Science (14 September 2018). Trials with this first independent, floating and free wing robot, completed in team with the University of Wageningen and Research, have improved our understanding of how natural product flies control the movements of animals. forced escape. In addition to its additional potential for scary flight study, the robot's extraordinary flight characteristics open up new applications for the robot.
Flying creatures are both powerful and controlled by flapping their wings. This allows small tractors features, for example, crawling animals to float near a flower, while quickly escaping the threat, which everyone has seen while trying to steal a fly. The flight of creatures has constantly attracted the attention of scientists, who have not only looked at their examples of confusing wing movements and their simplified features, but also their tangible and neuromotor frameworks in the middle such light movements. In recent times, flying creatures have become a source of motivation for the autonomy specialists, who are trying to create light, clever, efficient and versatile flying robots for scary sizes.
TU Delft scientists at MAVLab have come up with a new scary and lively flying robot. until here unmatched in its execution, but then with a basic outline simple and easy to create. As in flying creatures, the swinging wings of the robot, beating 17 times per second, are not limited to the expected lift load, but also control the flight by slightly changing the movement of the wings. Driven by flies of natural products, the robot's control systems have been deeply viable, allowing it not only to drift on the spot and fly to any trajectory, yet be extremely skilled.
"The robot has a top speed of 25 km / h and can even perform energetic movements, such as 360-degree, circle-like rollovers," says Mat. J Karásek, the main creator of the robot examination. "The 33 cm wingspan and the 29-gram robot have excellent energy efficiency for their size, allowing 5 minutes of flying adrift or more than 1 km of flight on a fully charged battery."
In addition to being a new miniaturized self-sufficient scale walk, the robot's flight displays, combined with its programmability, also make it suitable for scary flights. To this end, TU Delft is associated with the University of Wageningen. "When I saw the robot flying for the first time, I was amazed at how much its flight was like scary creatures, especially in motion. I quickly realized that we could really use it to examine scary flying elements and controls, "says Professor Florian Muijres of the University of Wageningen's Experimental Zoology and Research Meeting. Because of Professor Muijres' previous work on natural product flies, the group chose to program the robot to mimic the theoretical control activities of these critters in the midst of escape movements, for example those used to crush them.
The movements made by the robot closely resembled those seen in natural product flies. The robot was even ready to show how flies of organic products control the pivot point to boost their performance. "As opposed to creature tests, we fully controlled what was going on in the robot's" brain ". This allowed us to recognize and represent another streamlined system that helps flies, but perhaps at the same time other flying creatures. guiding their heads throughout these quick silver turns, "adds Karásek.
The MAVLab has been creating creepy flying robots for more than 10 years at DelFly. Professor Pido Guido de Croon, logical pioneer of MAVLab, says: "PLCs have a high potential for new applications because they are lightweight, safe for people and can fly more efficiently than conventional PLCs, especially in the little ones. Balance. In any case, until now, these flying robots had not understood this potential because they were not sufficiently flexible – for example, our DelFly II – or required a process to do it. assembly too complex. The robot in this review, called the DelFly Nimble, which extends to assembly techniques, uses spare parts and its flight perseverance is long enough to arouse the interest of genuine applications.
The DelFly Nimble will also be created within the TTW company, "As Able Bee", which is a joint effort of TU Delft and the University of Wageningen, funded by the Dutch scientific establishment NWO.
