Six electrodes are connected to the beetle's optic lobes and flight muscles. The entire device is powered by a 3. 9-volt micro lithium battery
"During test flights, signals were transmitted to the beetle backpack every millisecond, directing the beetles to take off, turn left or right,
or even hover in mid-flight. The beetles were untethered but in a closed room equipped with eight 3-D motion-capture cameras."
"In our earlier work using beetles in remote-controlled flight, we showed excellent control of flight initiation and cessation,
but relatively crude control of steering during free flight,"said Maharbiz.""Our findings about the flight muscle allowed us to demonstrate for the first time a higher level of control of free-flying beetles.

#Bio-inspired eye stabilizes robot's flight without need for an accelerometer Biorobotics researchers at the Institut des Sciences du Mouvement-Etienne-Jules Marey (CNRS/Aix-Marseille
All aircraft, from drones to the Ariane launcher, are equipped currently with an inertial measurement unit,
This allows these aircraft to stabilize their roll and pitch with respect to the horizon or rather with respect to its perpendicular:
An accelerometer measures all the accelerations of the aircraft including gravity, which is directed always toward the center of the Earth.
3) An inertial reference system is used an instrument in navigation that is able to process the measurements of a device's motion (acceleration and angular velocity) in order to estimate its orientation (angles of roll, pitch and heading.
Potential applications already exist for this emerging technology, such as medical imaging, the improvement of navigation systems or even for searches based on images rather than on text.

"Galli's team found that these defects enhance the transport of electrons. But more interestingly, they found that the nitrogen that had been incorporated into the compound increased the transport of electrons independent of the defects.
Finally, that nitrogen lowered the energy needed to kick electrons into the state in which they were available to split water.

#The UK is trialling a new road surface that charges your electric car as you drive One of the problems with being on the cutting edge of electric car technology is you're not as sure of being able to find a filling station as all the petrol-burning drivers around you.
If a new road surface being trialled in the UK finds wider use, that sort of'range anxiety'could be gone for good-the roads actually charge your car as you drive.
Highways England, the government organisation responsible for road infrastructure maintenance, is beginning tests later this year.
A select number of cars will be fitted with the requisite wireless charging technology and a test road will be built to show how smaller substations, AC/AC converters,
and power transfer loops can provide inductive charging built into the road itself. The exact details of the technology and how it works won't be confirmed until a contractor is appointed to set up the test route,
but the aim will be to simulate motorway conditions as closely as possible. It's not yet clear how much of a charge the tarmac is going to provide,
but it would certainly increase the amount of time cars could last between full charges at home or a designated charging station."

#London is now recycling energy from train brakes to power their stations London has just finished testing a new system that can collect
and recycle energy generated by their Tube trains when they brake, and it already powering their stations completely for more than two days per week.
which reportedly transports 1. 2 billion passengers across a total of 76.2 million km every year, with some stations catering to 89 million people.
"The trial puts London at the cutting edge of this kind of technology and clearly demonstrates how energy from trains can be recovered to power Tube stations,
"This complements our wider work to make other forms of public transport cleaner and greener, including our buses,
which has been installed at the Cloudesley Road substation on the Victoria line. The system works by collecting energy generated by the trains
when they brake before feeding it back into the power mains as electricity.""In hybrid and electric cars, such recovery systems can help improve range,
but in large heavily-packed passenger trains running regularly in one of the most heavily traveled cities in the world,
According to the London transport authority, it collected an average of 1 Megawatt hour (MWH) of energy each day,
