Envirobot, robotic eel to track source of water pollution

A robotic eel called Envirobot is designed to track the source of water pollution. Researchers at the École Polytechnique Fédérale de Lausanne (EPFL) along with other agencies developed robotic eels to swim in contaminated water to find sources of pollution. Water drone robot equipped sensors to be controlled remotely and able to produce conductivity map and measure water temperature.

The EPFL researchers as part of an ambitious project funded by the Swiss NanoTera Program have developed water robots to detect sources of water pollution. The 1.5-meter long envirobot equipped with chemical, physical, biological sensors and moves like an eel, without stirring mud or disturbing water life.

This robot is regularly tested on Lake Geneva which involves simulating water pollution by spreading salt to a small area offshore that thus alters the conductivity of water. The researchers launched robot to swim in contaminated areas and successfully mapped the conductivity variations and produced a temperature map.

"Many advantages to using swimming robots, they perform measurements and transmit data in real-time, much faster than the measuring stations installed around the lake," said Auke Ijspeert, head of Bioobobics EPFL Laboratory (BioRob).

"Conventional propeller-based robots tend to get trapped in algae while moving, while Envirobot produces less wake, so they do not spread the pollutants at all, following the programmed track and independently making own decisions to track sources of pollution," Ijspeert said.

The robot consists of many modules that each contain small electric motor to change the curvature. The modular design allows the engineers to change the composition and vary the length as needed. Some modules contain conductivity and temperature sensors.

"Robots are easily separated and carried away, then reassembled to start testing," said Behzad Bayat, BioRob researcher. Envirobot, robotic eel to track source of water pollution

The small rooms contain biological sensors that accommodate bacteria, small crustaceans or fish cells. The sensor works by observing how the organism reacts when connected with water to provide an indication of whether there are certain key pollutants and water toxicities in general.

"For example, we develop bacteria that produce light when exposed to very low mercury concentrations. We detect these changes using luminometer and transmit data in form of electrical signals," said Jan Roelof van der Meer, Project Coordinator and Head of the Department of Fundamental Microbiology at University of Lausanne.

European Union and ASEAN to restart Free Trade Agreement

Tinuku - European Union (EU) and ASEAN have agreed to restart the process of forming Free Trade Agreement (FTA). Singapore Prime Minister Lee Hsien Loong as ASEAN coordinator for EU-ASEAN relations said on Saturday to build a framework to identify potential sectors to finalize the deal.

Lee also said the EU and ASEAN had agreed to restart the process of establishing a free trade agreement between the two blocs. The EU and ASEAN launched talks towards a pact in 2007 but ignored the process two years later as the EU voted to negotiate bilaterally with each country.

"As coordinators, we look forward to forming a framework to identify where areas where we have the potential to make a deal," Lee said.

"Working on a deal may take longer than the end of the year. But if we can identify where the big opportunities are, our trade-offs, then I hope we will have better success," Lee said.

"One of the things we expect is that European nations are able to manage their soci…

Rolls-Royce plans for flying taxi service

Tinuku - Rolls-Royce Holdings plc has designed a propulsion system for flying taxi and is starting search for partners to help develop a project it hopes could take to the skies as soon as early next decade. British jet engine maker said on Sunday it had drawn up plans for an electric vertical take-off and landing (EVTOL) vehicle which could carry to five people at speeds of up 250 mph for approximately 500 miles.

The company joins a variety of companies racing to develop flying taxis, which could revolutionize the way people travel. Aviation and technology leaders are working to make electric-powered flying taxis a reality, including Airbus, U.S. ride- sharing firm Uber and a range of start-ups including one backed by Google co-founder Larry Page, called Kitty Hawk.

Rolls-Royce’s design will be showcased in digital form at the Farnborough Airshow, which starts on Monday. The company is looking for an airframer and a partner to provide aspects of the electrical system to help commerci…

Britain announced its first launch site for the space market

Tinuku - UK on Monday ran an important leap for the construction of the first vertical launch space launch site. The proposed space port at Sutherland in the north of Scotland has been awarded US$3.3 million in funding by the government-owned UK Space Agency to develop a ground-breaking launch site.

Government Business Secretary Greg Clark Monday launched the start of a Great British Space Age that will see vertically-launched space rockets and satellites take off from the new spaceport. UK Space Agency said it selected the Sutherland site because Scotland is the best place in Britain to reach highly sought-after satellite orbits with vertically launched rockets.

The initial funding will go to Scotland's Highlands and Islands Enterprise agency to develop the Sutherland site which will use a combination of proven and innovative rocket technologies to pave the way for a world-leading spaceflight market.

The UK Space Agency is also making available a new 2.65 million U.S. dollar fund…
