Drones learn to navigate by imitating Cars and Bicycles Autonomously

CADDZOOM

The commercial drones these days make use of the Global Positioning System (GPS) to traverse. Such a method works fine when the drones fly at a high altitude. But the real hurdle arises when these drones navigate autonomously at a lower altitude. At such low altitudes, there are several issues such as

  • More density of building
  • Unstructured stress with the movement of several vehicles and humans.

The drones at this level have not reached to such a stage where they can react to an unforeseen event quickly. There are ways to enhance the functionalities of these drones.

Integration of autonomous navigation in drones

The development of DroNet by researchers at the National Centre of Competence in Research (NCCR) Robotics and the University of Zurich shows that autonomous navigation of drone is possible. It is an algorithm that helps the drones to fly through the busy streets of a city safely. With the help of one input image, it produces two outputs:

  • A steering angle and
  • A collision probability

The former helps the drone to avoid accidents, while the later helps it to identify the dangerous situations and react to them.

Powerful artificial intelligence algorithm

A team of Swiss researchers sought the help of a powerful algorithm and a normal smartphone camera to make the drones smarter. The combination helped the drone interpret the real-time situation and react accordingly. The algorithm used, consisted of Deep Neural Network.

Teaching the Drones through Cars and Bicycles

The collection of training examples is one of the biggest issues in Deep Learning. The drones can learn by imitating the driving behavior in the examples. Thus, Prof. Scaramuzza, along with his team collected the data from cars and bicycles driving in urban areas.

Fully autonomous drones – The Future

Through this research, the doors are open to several applications such as parcel delivery, surveillance and much more. The drones can drive within the clustered roads, with ease and save a lot of time. However, the team cautions from expecting too much from cheap drones.

Four Key Advanced Manufacturing Technologies Used in Aerospace

CADDZOOM

Advanced Manufacturing technologies have become one of the most important parts of the Aerospace industry. This is because of the unique challenges that the aircraft designers deal with. The aircraft designs need to consider the environmental conditions using strong materials that are both lightweight and temperature resistant. Such designs require micro and Nano- machining techniques. Here are four advanced machining technologies that are used in the Aerospace industry.

Additive Manufacturing  

The Aerospace industry was quick to identify the benefits and potential of Additive Manufacturing to design its planes. The technology uses Power-Bed laser printing systems to build its most components. Additive manufacturing technology is used to build structures that work within the fuselage with features such as reduced weight and reduce heat. An additive manufacturing technique, commonly known as the Fused Deposition Modeling, is used to create semi-hollow parts of the aircraft wings by both adding strength and reducing weight.

Composite Materials

Composite materials are widely used to design aircraft. Aerospace engineers prefer using these materials because of their favorable characteristics of flexibility, strength, temperature and chemical resistance. Composite materials and advanced polymers in the design help to improve performance and reduce lifecycle costs. These materials also reduce the overall weight of the aircraft cutting short their fuel consumption and carbon emissions.

Robotics

Robots are used in the aerospace industry to manage the labor-intensive process, particularly when lifting and handling tasks are to be done. The industry is using powerful robots in its manufacturing plants to move and join aircraft parts. Robotics is also taking care of manufacturing process that is hazardous to people such as painting and welding.

Laser Beam Welding

This technology offers rapid and high precision work as compared to the traditional welding techniques. Laser welding is, therefore, a preferred solution for handling materials when repeatability and high accuracy is required. The most advantageous property of this technique is that it transfers very little heat to the material that is welded. This way it does not create a heat affected zone around the weld, ultimately not compromising the strength and performance of the material.

With the widespread use of these technologies, the aerospace industry has also inspired several other industries to use these technologies in the manufacturing process. These techniques have undoubtedly simplified the manufacturing processes and reduced costs to a greater extent. Their accuracy and precision have reduced the number of failure points in the manufacturing process.
