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: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Studying fundamental particles in materials

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
