#Delivery by drone: New algorithm lets drones monitor their own health during long package-delivery missionsin the near future the package that you ordered online may be deposited at your doorstep by a drone:
Last December online retailer Amazon announced plans to explore drone-based delivery suggesting that fleets of flying robots might serve as autonomous messengers that shuttle packages to customers within 30 minutes of an order.
To ensure safe timely and accurate delivery drones would need to deal with a degree of uncertainty in responding to factors such as high winds sensor measurement errors or drops in fuel.
But such what-if planning typically requires massive computation which can be difficult to perform on the fly.
The team first developed an algorithm that enables a drone to monitor aspects of its health in real time.
With the algorithm a drone can predict its fuel level and the condition of its propellers cameras and other sensors throughout a mission and take proactive measures--for example rerouting to a charging station--if needed.
The researchers also devised a method for a drone to efficiently compute its possible future locations offline before it takes off.
The method simplifies all potential routes a drone may take to reach a destination without colliding with obstacles.
In simulations involving multiple deliveries under various environmental conditions the researchers found that their drones delivered as many packages as those that lacked health-monitoring algorithms--but with far fewer failures or breakdowns.
With something like package delivery which needs to be done persistently over hours you need to take into account the health of the system says Ali-akbar Agha-mohammadi a postdoc in MIT's Department of Aeronautics and Astronautics.
Interestingly in our simulations we found that even in harsh environments out of 100 drones we only had a few failures.
Agha-mohammadi will present details of the group's approach in September at the IEEE/RSJ International Conference on Intelligent Robots and Systems in Chicago.
In this regard he and his colleagues used POMDP to generate a tree of possible health outcomes including fuel levels and the status of sensors and propellers.
which drones were tasked with delivering multiple packages to different addresses under various wind conditions and with limited fuel.
They found that drones operating under the two-pronged approach were more proactive in preserving their health rerouting to a recharge station midmission to keep from running out of fuel.
Even with these interruptions the team found that these drones were able to deliver just as many packages as those that were programmed to simply make deliveries without considering health.
The researchers have attached electromagnets to small drones or quadrotors enabling them to pick up and drop off small parcels.
The team has programmed also the drones to land on custom-engineered recharge stations. We believe in the near future in a lab setting we can show what we're gaining with this framework by delivering as many packages as we can
while preserving health Agha-mohammadi says. Not only the drone but the package might be important
and if you fail it could be a big loss. This work was supported by Boeing.

#Bionic liquids from lignin: New results pave the way for closed loop biofuel refinerieswhile the powerful solvents known as ionic liquids show great promise for liberating fermentable sugars from lignocellulose
and improving the economics of advanced biofuels an even more promising candidate is on the horizon--bionic liquids.
Researchers at the U s. Department of energy's Joint Bioenergy Institute (JBEI) have developed bionic liquids from lignin and hemicellulose two by-products of biofuel production from biorefineries.
Our concept of bionic liquids opens the door to realizing a closed-loop process for future lignocellulosic biorefineries
The JBEI researchers tested the effectiveness of their bionic liquids as a pre-treatment for biomass deconstruction on switchgrass one of the leading potential crops for making liquid transportation fuels.
After 73 hours of incubation with these new bionic liquids sugar yields were between 90-and 95-percent for glucose and between 70-and 75-percent for xylose.
and reused to make more bionic liquid says lead author Socha who is now the Director of the Center for Sustainable Energy at The bronx Community college in New york city.
The current batch of bionic liquids was made using reductive amination and phosphoric acid but Socha says the research team is now investigating the use of alternative reducing agents
Our results have established an important foundation for the further study of bionic liquids in biofuels as well as other industrial applications he says.

#Silicon oxide for better computer memory: Use of porous silicon oxide reduces forming voltage, improves manufacturabilityrice University's breakthrough silicon oxide technology for high-density next-generation computer memory is one step closer to mass production thanks to a refinement that will allow manufacturers to fabricate devices at room temperature with conventional
production methods. First discovered five years ago Rice's silicon oxide memories are a type of two-terminal resistive random-access memory (RRAM) technology.
This memory is superior to all other two-terminal unipolar resistive memories by almost every metric Tour said.
The basic concept behind resistive memory devices is the insertion of a dielectric material--one that won't normally conduct electricity--between two wires.
RRAM is under development worldwide and expected to supplant flash memory technology in the marketplace within a few years
For example manufacturers have announced plans for RRAM prototype chips that will be capable of storing about one terabyte of data on a device the size of a postage stamp--more than 50 times the data density of current flash memory technology.
and even used it for exotic new devices like transparent flexible memory chips. At the same time the researchers also conducted countless tests to compare the performance of silicon oxide memories with competing dielectric RRAM technologies.
and a performance standpoint for nonvolatile memory Tour said. It can be manufactured at room temperature has an extremely low forming voltage high on-off ratio low power consumption nine-bit capacity per cell exceptional switching speeds and excellent cycling endurance.
and multi-bit capacity--are extremely appealing to memory companies. This is a major accomplishment and we've already been approached by companies interested in licensing this new technology he said.
Meteorological conditions and landscape complexity as factors for variationthe scientists fixed RFID microchips onto the thorax of nearly a thousand bees.
These microchips were able to check on the return to the hive of individuals thanks to a series of electronic sensors.
Exposure to low doses of pesticide thus appeared to alter their ability to call upon their spatial memory.

#Whats the role robotics could play in future food production? A team of computer scientists from the University of Lincoln UK is co-organising an international workshop on recent advances in agricultural robotics.
Academics from the Lincoln Centre for Autonomous Systems (L-CAS) will be attending the 13th International Conference on Intelligent Autonomous Systems (IAS-13) from 15th to 19th july 2014.
Recent results confirm that robots machines and systems are rapidly achieving intelligence and autonomy mastering more and more capabilities such as mobility and manipulation sensing and perception reasoning and decision making.
and industrial communities to discuss recent advances in robotic applications for agriculture and horticulture. The world's rapidly growing population brings new challenges for global food security.
Agricultural robotics is one of the promising technological solutions for addressing these problems. Dr Grzegorz Cielniak senior lecturer in the School of Computer science said:
The workshop will provide a forum to present the state-of-the-art technical solutions in agricultural robotics
and new exciting robotics platforms but also to encourage future collaborations between the participants. Recent examples have shown agricultural robotics autonomously performing a number of different agricultural tasks from monitoring soil
and crop properties and harvesting fruit in orchards to mechanical weeders eliminating the need for herbicides to produce affordable safer food.
Using teams of small specialised agricultural robots instead of the currently used heavy machinery can result in lower soil compaction leading to energy savings but also in more robust systems in the case of technical failures.
Projects involving L-CAS include a 12-month feasibility study funded by a £132000 grant from the Technology Strategy Board to create a system of laser sensors to accurately control agricultural sprayers.
#Drones give farmers an eye in the sky to check on crop progressthis growing season crop researchers at the University of Illinois are experimenting with the use of drones--unmanned aerial vehicles--on the university's South Farms.
Dennis Bowman a crop sciences educator with U. of I. Extension is using two drones to take aerial pictures of crops growing in research plots on the farms.
Watch the drone in action. We're also looking at doing some scans over our herbicide studies to see
if the drone photography can help us identify where crops are stressed by postemergence herbicide applications.
For farmers aerial photographs taken by drones offer a quick and easy way to check on the progress of crops
To get a bird's-eye view of your crop the drones offer a handy way to do it.
Both drones Bowman is using are multirotor helicopters or quadricopters. Bowman bought the first drone last fall.
It's a remote-controlled Phantom manufactured by the company DJI. This spring he bought a second aircraft an A r. Drone 2. 0 with GPS produced by The french wireless electronics manufacturer Parrot.
Using rechargeable lithium polymer batteries each drone can make flights of about 10 to 15 minutes.
The computers in the drones are similar to those used in smartphones. The Phantom which cost about $500 was a ready-to fly model equipped with a mount for a Gopro camera.
With the addition of the mount a camera and a gimbal to keep the camera level Bowman's total investment was about $1000.
When the Phantom is turned on its computer starts the GPS and the flight control system runs through a one-to two-minute process of locating
and locking on to GPS satellites to establish the drone's home position. If launched properly by allowing the flight control system to orient itself with the satellites the Phantom drone will return to within 1 meter of its home position
When I'm running the Parrot drone during a conference I pick somebody that looks scared when
'and the drone pops up 3 feet in the air hovers and waits for you to take over flying it.
Standard pictures and video taken with drones can tell us a lot Bowman said. But what we're looking to give us even more information is multispectral cameras that can give us imagery in other wavelengths such as near-infrared to help us identify areas of crop stress.
The drones also may be deployed in the battle against Palmer amaranth an invasive weed that is spreading across the Midwest
although growing numbers of hobbyists have been toying with the use of drones particularly for aerial photography.
However facing mounting pressure from agribusiness retail and other industries the FAA is expected to release new policies by 2015 that will enable businesses to integrate drones into their operations.
The agriculture industry is expected to be one of the largest market segments for drone usage.

Feeding acute and chronic doses to honeybees--beyond the levels they would ever experience in the field--the team found it had only a very slight effect on the bees'survival and no measurable effect at all on their learning and memory.
Throughout the study period the team carried out a series of memory tests and recorded any changes in behaviour.
This is an oral pesticide so unlike some that get absorbed through the exoskeleton the spider/snowdrop recombinant protein has to be ingested by the insects.
and memory in bees so it's vital that any pesticide targeting them does not interfere with this process explains Erich.
