Minihelicopter Flies Autonomously

12.12.2011
Siemens uses a minihelicopter equipped with onboard sensors to collect and interpret videos.

Known as the quadrocopter, the aircraft uses the data to create a 3D digital model of its immediate surroundings.


As reported in Pictures of the Future magazine, computer scientists working for Corporate Technology in Princeton and Munich have teamed up with robotics experts from the Massachusetts Institute of Technology near Boston to develop this sophisticated eye in the sky.

The aim of the project is to create a system capable of producing digital models of complex interiors and inspecting inaccessible installations.

For researchers working in artificial intelligence, the development of a system with visual competence remains, even after 50 years, a major challenge. When it comes to looking at the real world, computers are still remarkably primitive. Whereas a young child has no problem distinguishing a tree from an antenna, computers are incapable of reliably matching such images to the relevant object. Research groups from both science and industry are therefore working hard to enhance the visual capability of artificial systems.

At Siemens, researchers are progressively teaching the quadrocopter how to see. The unmanned system measures almost one meter in diameter and is equipped with four rotors. When in flight, it uses lasers to scan its surroundings. Optical sensors and video cameras record every detail.

In a process known as "supervised learning," such systems are initially primed with hundreds of thousands of images, thereby imitating the process whereby a child learns to distinguish, say, a tree from an antenna mast on the basis of having already seen a countless number of objects. Intelligent algorithms then search these images for characteristic features. On this basis, the quadrocopter is able to compile a precise 3D digital model of its surroundings in areas such as baggage-handling facilities, factory buildings, or event venues for the purposes of construction planning or building inspection. In the future the aircraft can fly routine operations to inspect largely inaccessible installations such as wind power plants and electricity pylons.

In other projects at a number of its research and development facilities, Siemens is also developing systems that are able to scan aireal images for complex patterns such as industrial sites, buildings, or roads; examine X-ray images of baggage and shipping containers for suspicious objects; identify and read road signs; and monitor crowds.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
