Today's robots are far smarter and more capable than the clumsy and awkward robots of the 1980s and 1990s. And although we have a long way to go before autonomous robots reach the sophistication of TV science fiction, we do seem to be getting closer. Engineers, entrepreneurs and academics from the US and UK met this week to think out loud about the past, present and future of robotics during a conference hosted by the British Consulate General, a short walk from the Massachusetts Institute of Technology (MIT) in Cambridge. The robotics and artificial intelligence sectors will be a 2.6 trillion industry by 2020, according to the consulate, with robots playing an ever-larger role in healthcare, military and autonomous systems such as self-driving cars, unmanned aerial vehicles and surface/underwater drones. I went to the conference to investigate a simple question: are the robots we're researching, designing and building today secure against hackers?

The Pentagon, the world's largest user of drones, has posted a new policy on signs outside the mammoth five-sided building: No Drone Zone. The signs, complete with a red slash through an image of a quadcopter drone, reflect America's growing concern about the proliferation of the small, inexpensive remote-controlled devices and the risk they pose to safety, security and privacy. Federal law prohibits flying a drone anywhere in and around Washington, an area known as the National Capital Region. Other communities and institutions across the country are wrestling with the potential threat from more than 400,000 private and commercial drones now registered to operate in the skies. The pilot of a commercial jetliner said his plane nearly collided with a drone while approaching Los Angeles International Airport on Friday afternoon, sparking a search by L.A. police and sheriff's officials for the owner of the unmanned aircraft.

A drone flies Feb. 27, 2015, over Reims, northwestern France. SAN FRANCISCO -- The national group that represents companies that make and sell drones has split, with those focused on consumers leaving to form their own organization. Four drone companies left the Small UAV Coalition on Thursday. While still tightly aligned with the coalition on big issues, the break-away companies plan to create a still-unnamed group to very specifically focus on consumer issues, said GoPro spokesman Jeff Brown. As the drone market matures, a shifting of needs was inevitable. Larger companies such as Amazon's Prime Air, Alphabet's Google X and others are looking more at drones for delivery, cargo and more commercial uses.

Students who created a record-breaking remote-controlled multicopter drone say they hope to get permission to fly a person in its structure. The University of Oslo team built the large unmanned aerial vehicle (UAV), dubbed the Megakopter, over an 18 month period. It contains 13 propellers and eight hexacopters powered by a total of 48 motors that reside on a frame built from aluminum and plywood. Students who created a record-breaking remote-controlled multicopter drone say they hope to get permission to fly a person in its structure. The drone cost more than 200,000 Norwegian kroners ( 21,600 or 15,000) to make and took two years.

Child care is a hard job, but somebody, or something, has got to do it. Japanese researchers have developed androids to meet that need, which includes happily reading that fairy tale again and again and again. The androids, which were created by a team of education and robotics specialists at a research facility in Abiko, Chiba Prefecture, are part of a larger system called RoHo Care. Short for Robotic Hoikujo (day care center), RoHo is being touted as a high-tech solution to the staffing crisis that forced the Health, Labor and Welfare Ministry to announce emergency measures this week. "I never thought I'd see this day, but we're now confident that RoHo could blaze a trail for child care worldwide," said team leader Makoto Hara.

State Farm is the first insurer to gain FAA approval for commercial drone use which may help pave the way for widespread commercial use of unmamed aerial vehicles.

A team of Nevada scientists have been using a drone to control the weather. Engineers and meteorologists say they have created the first autonomous cloud seeding platform that could increase rainfall by 15 per cent. Cloud seeding involves spraying fine particles of silver iodide into a cloud system in an effort to boost the amount of rain that falls. A team of Nevada scientists have been using drones to control the weather. Microscopic particles of silver iodide are shot into existing clouds using land based generators or aircraft.

Tsetse flies feast on animal blood. When they do so, humans can get Trypanosomiasis, or sleeping sickness, which starts as exhaustion and fever, and can lead to death if left untreated. In animals, the tsetse's bite can develop into paralysis. Tsetse flies are limited to sub saharan Africa, where they infect at least 10,000 people a year. It's a mess of an insect, but an organization in Spain thinks they have a solution, and they're going to use drones to deliver it. "Drones Against Tsetse" is a project by spanish dronemaker Embention, together with the International Atomic Energy Agency.

It may not be good news for anyone who finds insects creepy. Scientists have proved they can control how beetles fly and walk by turning them into cyborgs. Researchers fitted giant flower beetles, which measure two inches long and weigh around 0.3 ounces, with radio transmitter backpacks and wired them to their limbs. This allowed them to electrically stimulate muscles in the insects' legs so they could control their walking speed, gait and direction. Scientists have shown they can control the movement of giant flower beetles by inserting tiny electrodes into their muscles.

Delivery by drone may be legal within two years. Just don't expect many pizzas or packages to wing their way through your neighborhood by then. Despite huge interest in unmanned aerial vehicles (UAVs), and considerable hype around the idea of using them to deliver goods, experts say significant challenges still need to be solved for drone delivery to get off the ground. Google and Amazon are leading the development of delivery drones, while UPS, FedEx, and a host of startups are also researching the technology. Earlier this month, the U.S. Senate Transportation Committee drafted a bill that paves the way for regulation of delivery drones within two years.
