Given that the battery life of most multicopter drones typically doesn’t exceed 30 minutes of flight time per charge, there are many tasks that they simply can’t perform. Feeding them power through a hard-wired tether is one option, although that only works for applications where they’re hovering in place. Scientists at Imperial College London, however, are developing an alternative – they’re wirelessly transferring power to a drone as it’s flying.
For their study, the scientists started with an off-the-shelf mini quadcopter. They proceeded to remove its battery, add a copper coil to its body, and alter its electronics.
The researchers also built a separate transmitting platform that uses a circuit board, power source and copper coil of its own to produce a magnetic field. When placed near that platform, the drone’s coil acts as a receiving antenna for that magnetic field, inducing an alternating electrical current. The quadcopter’s rejigged electronics then convert that alternating current to direct current, which is used to power its flight.

Verizon has joined the likes of Facebook, Google and fellow telecommunications giant AT&T in exploring the potential of internet-connected unmanned aircraft. While its vision involves expanding 4G coverage across the US, it has an immediate focus on shoring up communications for first responders in emergency situations, and recently carried out trials to that effect.
Verizon has dubbed the initiative Airborne LTE Operations (ALO) and says it has actually been in the pipeline for around two years. The company has been working to integrate internet connectivity into unmanned aerial vehicles and hook them up to its 4G network, daisy chaining coverage and beaming it down to unconnected areas in the process. This is similar to how Facebook hopes its Aquila drones will work.
Verizon recently teamed up with company American Aerospace Technologies to see how using drones as gliding cell towers could have an impact in disaster relief scenarios. In a simulated mission in New Jersey, the team set a drone with a 17-foot (5.2 m) wingspan in flight to put the onboard technologies through their paces.

Got a bee shortage? No problem, DARPA has you covered.
Following the news that the honeybee is now officially an endangered species as “colony collapse disorder” accelerates, it seems that a Harvard research team has the solution – robotic honeybees. Instead of attempting to save the bees by reducing the use of pesticides or revising safety standards for cell phone radiation, the focus has shifted to replacing the bees altogether. Harvard University researchers, led by engineering professor Robert Wood have been tweaking “RoboBees” since their initial introduction in 2009. The bee-sized robots made of titanium and plastic represent a breakthrough in the field of micro-aerial vehicles. The size of the components needed to create flying robots were previously too heavy to make a such a small structure lightweight enough to achieve flight. Current models weigh only 80 mg and have been fitted with sensors that detect light and wind velocity.
Researchers claim that the bees could artificially pollinate entire fields of crops and will soon be able to be programmed to live in an artificial hive, coordinate algorithms and communicate among themselves about methods of pollination and the locations of particular crops. In addition, RoboBees have been suggested for other uses including searching disaster sites for survivors, monitoring traffic, and “military and police applications.” These applications could include using RoboBees to “scout for insurgents” on battlefields abroad or allowing police and SWAT teams to use the micro-robots to gather footage inside buildings.
The RoboBees project originally began at the University of California at Berkeley in 1998 when neurobiologist Michael Dickinson, electrical engineer Ron Fearing, and then-grad student Rob Wood received a $2.5 million grant from DARPA to create an insect drone. Dickinson now continues his work at the University of Washington while Wood heads the principal RoboBee micro-robotics lab at Harvard. DARPA, the Defense Advanced Research Projects Agency of the US military, is best known for its role in helping create the internet, but a vast majority of their taxpayer-funded projects paint a decidedly dystopian picture of humanity’s future. Most of DARPA’s projects involve transhumanism, the merging of humans and machines to create a technologically governed populace.

Cool new story in the San Francisco Chronicle about the robotics conference. I gave a speech at it yesterday.
At the two-day RoboBusiness Conference, about 2,000 people were serenaded with lullabies and Disney tunes, including “Let It Go” from the hit film “Frozen,” by a human-like robot designed to comfort senior citizens and autistic children.
And next to a man-size robot that can drive a motorcycle 190 mph around a race track, a half-dozen ant-size robots quickly scurried about a miniature factory floor.
“In five years, could you imagine what this conference is going to look like?” Transhumanist Party presidential candidate Zoltan Istvan asked the crowd. “There are going to be 8-foot robots walking all around us, talking to us, some of them maybe being smarter than us.”
