… bringing scalability to the quantum cloud. The new development is scalable and suitable for use in photonic quantum computers. An international team of researchers from Leibniz University Hannover (Germany), the University of Twente (Netherlands), and the start-up company QuiX Quantum has presented an entangled quantum light source fully integrated for the first time on a chip. “Our breakthrough allowed us to shrink the source size by a factor of more than 1000, allowing reproducibility, stability over a longer time,…
In order to achieve optimum product quality, precise control of the production process is necessary. For this purpose, the relevant parameters must be continuously recorded. In this context, the Fraunhofer Institute for Surface Engineering and Thin Films IST from Braunschweig will be presenting its most recent developments for the optimization of cotter rolling processes at this year’s Hannover Messe: Thin-film sensor inserts which enable precise in-situ detection of the temperature distribution on the tool surface. In collaboration with the Institut…
The Fraunhofer Institute for Digital Media Technology IDMT will present a novel monitoring method for industrial production at the most important international industrial trade fair from April 17 to 21, 2023 in Hannover. At the booth of the Fraunhofer-Gesellschaft (Hall 16, Booth A12), the Ilmenau-based research institute invites all visitors to test the reliability of the acoustic monitoring method for themselves at an interactive demonstrator. Based on artificial intelligence (AI), acoustic monitoring can be used for the quality assurance of…
Virtual 3D models of real objects offer numerous advantages – be it for digitization or in the quality control of industrial manufacturing. But the more complex an object, the more difficult it is to measure its shape and transfer it to a 3D model. Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF, in collaboration with MTU Maintenance, have now developed a portable sensor that enables particularly flexible 3D capture, for example of aircraft engines. The handheld…
Energy-efficient robot hand learns how not to drop the ball. Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects – and not drop them – using just the movement of its wrist and the feeling in its ‘skin’. Grasping objects of different sizes, shapes and textures is a problem that is easy for a human, but challenging for a robot. Researchers from the University of Cambridge designed a soft, 3D printed robotic hand that…
The three-fingered robotic gripper can “feel” with great sensitivity along the full length of each finger – not just at the tips. Inspired by the human finger, MIT researchers have developed a robotic hand that uses high-resolution touch sensing to accurately identify an object after grasping it just one time. Many robotic hands pack all their powerful sensors into the fingertips, so an object must be in full contact with those fingertips to be identified, which can take multiple grasps….
… and act in challenging environments. UCLA-led team built chip-free, autonomous OrigaMechs with conductive materials. Roboticists have been using a technique similar to the ancient art of paper folding to develop autonomous machines out of thin, flexible sheets. These lightweight robots are simpler and cheaper to make and more compact for easier storage and transport. However, the rigid computer chips traditionally needed to enable advanced robot capabilities — sensing, analyzing and responding to the environment — add extra weight to…
Conventional concepts from the manufacturing industry are increasingly being pushed to their limits. This is often due to a combination of current challenges like volatile markets, supply crises and rising energy prices. Researchers at the Fraunhofer-Gesellschaft have developed an innovative production architecture that addresses these challenges. This architecture relies on modular production rather than rigid process chains. Orders are issued in a newly developed production language and carried out autonomously by machine tools or robots. This way, manufacturers can adapt…
The technology of “the glasses that replace the guide dog” has just been patented in the USA. The European Union patent will follow, and it could well be introduced to the market during the course of next year. Cornel Amariei, a graduate of Bremen’s Constructor University and founder of the start-up .lumen, is convinced that these glasses will give people with blindness and visual impairments a whole new level of mobility and self-determination. Around 40 million people worldwide are affected…
Carlo D’Eramo is new at the University of Würzburg. The computer science professor works in the field of artificial intelligence. He is an expert in a special form of machine learning called reinforcement learning. An intelligent camera surveillance system is supposed to autonomously detect stray pieces of luggage or other suspicious objects at a railway station. To do this, it has to know what suitcases and bags look like. To achieve this, humans have to feed the system with training…
Researchers create a trajectory-planning system that enables drones working together in the same airspace to always choose a safe path forward. When multiple drones are working together in the same airspace, perhaps spraying pesticide over a field of corn, there’s a risk they might crash into each other. To help avoid these costly crashes, MIT researchers presented a system called MADER in 2020. This multiagent trajectory-planner enables a group of drones to formulate optimal, collision-free trajectories. Each agent broadcasts its…
Will enable powerful AI in your portable devices. Everyone is talking about the newest AI and the power of neural networks, forgetting that software is limited by the hardware on which it runs. But it is hardware, says USC Professor of Electrical and Computer Engineering Joshua Yang, that has become “the bottleneck.” Now, Yang’s new research with collaborators might change that. They believe that they have developed a new type of chip with the best memory of any chip thus…
“Seven, one, nine, …”: A human voice pronounces digits, a physical material recognizes them with about 97 percent accuracy. This pattern recognition system was developed by physicists at the University of Duisburg-Essen (UDE) in collaboration with Ghent University (Belgium). The development enables multidimensional problems to be solved quickly and without energy-consuming training. The scientific journal Advanced Intelligent Systems published the results. Is it possible for an inanimate material to recognize patterns quickly and efficiently? That was the question asked by…
… in an important step for the quantum internet. Researchers have discovered a way to “translate” quantum information between different kinds of quantum technologies, with significant implications for quantum computing, communication, and networking. The research, published in the journal Nature on Wednesday, was funded by the Army Research Office (ARO), the Air Force Office of Scientific Research (AFOSR), and the NSF Quantum Leap Challenge Institute for Hybrid Quantum Architectures and Networks (HQAN), which is led by the University of Illinois Urbana-Champaign. It represents…
Hannover Messe 2023: At the booth of Fraunhofer-Gesellschaft (Hall 16, A12) at Hannover Messe (April 17–23, 2023), Fraunhofer FIT will provide insights into the Industrial Metaverse. The demonstrator for remote maintenance and training in mechanical engineering and production uses high-speed wireless Internet, remote rendering of CAD data, and mobile mixed reality / virtual reality headsets. The system is being implemented and tested in a real-life setting in the 5G Troisdorf IndustrieStadtpark project. The Industrial Metaverse promises a range of benefits…
Researcher awarded for the development of compact high-power EUV source. The future has a color: it is extreme ultraviolet. With the help of EUV light it is possible, for example, to produce smaller and more powerful microchips than ever before. But further research faces a problem: Experiments with laser-like EUV light can usually only be conducted at expensive large-scale research facilities. Jena scientist Robert Klas wants to change that. He has developed a compact EUV laser module that can be…
