La Libra, Facebook's digital currency, announced for 2021 in reduced format

The launch of Facebook's digital currency, Libra , could take place in 2021. The project may benefit from favorable factors in the global economy, but regulators will have to be convinced first.  Facebook could launch Libra, its digital currency in 2021, we learn from the British media Financial Times, which quotes people close to the process. The product is expected to arrive in a limited version, after the project has met with great aversion from regulators, including in the United States, the country where the headquarters of the social media management company are located. The stakeholder association behind this digital currency project is now planning to launch a single version of Libra that will itself be pegged to the dollar, at the rate of one unit of US currency for each Facebook digital currency . “The other forms of currencies will be deployed at a later stage,” the FT source added. The exact launch date will depend on when the project

Astronauts adopt Mozilla voice technology to control lunar robots

Technology: The text-to-speech engine will allow astronauts to find their hands free to perform complex tasks.

Mozilla’s Deep Speech learning engine leaves planet Earth to help astronauts. This week Mozilla, the creator of the Firefox web browser, revealed a new project with the German Aerospace Center, also known as Deutsches Zentrum für Luft- und Raumfahrt (DLR), to integrate Mozilla's voice technology into the lunar robotics.

 
Astronauts adopt Mozilla voice technology to control lunar robots


Robots are often used in space applications to increase the capabilities of astronauts who work on tasks including maintenance, repair, carrying out experiments, and collecting samples. While robots are also being considered for mining on the surface of the Moon, for now, they are useful in helping astronauts.

But the challenge that astronauts face in space is to effectively control the robots while performing tasks that require the use of their hands. According to Mozilla, the Deep Speech automatic speech recognition (ASR) engine and the speech-to-text device make it possible “to control the voice of robots when astronauts have their hands busy”.

“Deep Speech is composed of two main subsystems: an acoustic model and a decoder. The acoustic model is a deep neural network that receives audio input characteristics, and produces character probabilities. The decoder uses a beam finder algorithm to transform the probabilities of characters into text transcripts which are then returned by the system. "




The German space agency is working hard to integrate Deep Speech, and the organization also plans to contribute to the Mozilla project - potentially through tests, speech examples and recordings that could improve the accuracy of the program. It is not yet known which robots will receive the voice recognition upgrade. But DLR was responsible for the design of a robotic mobile unit, Rollin ’Justin, created to test collaboration between astronauts and robots on difficult terrain.

The DLR Institute of Robotics and Mechatronics also conducts research on the performance of robotics using the European Multipurpose End to End Robotic Network (METERON) on the International Space Station. In 2015, DLR launched the SpaceBot Cup, a robotics competition bringing together 10 German universities and research centers, to create robots capable of mapping difficult terrain, collecting samples and going to a base without using the GPS positioning.
