Parrot’s new ‘follow me’ feature keeps drone eyes on you

Parrot has launched a new ‘follow me’ in-app feature for its drones that makes use of visual tracking to allow the Parrot Bebop 2 to follow you everywhere, keeping you in frame for all those times you absolutely need to have footage as you scale a mountain.

The new feature is used from within the FreeFlight Pro app and combines the new visual tracking with your smartphone’s GPS and barometer.

Your smartphone handles all of the positioning, though you may lose some of the accuracy if your phone is without a barometer for vertical tracking, while the visual tracking supposedly mimics the human eye with algorithms to better differentiate between user and environment.

The feature provides two different modes of operation: auto follow and auto framing. The auto follow mode is essentially designed for getting the perfect footage of you whether you’re walking, running or climbing a mountain. Once you’ve set the flight altitude, distance from subject and video angle, you’re ready to go and the drone will follow along with you centrally framed.

Within the auto follow mode itself there are multiple functionalities that allow you to customise the shot to get the perfect shot. Perfect Side allows you to set a shooting angle that the Bebop 2 will follow by determining your position in regards to the angle, while Magic Dronies offers the choice of several pre-programmed movements including a 360 degree orbit around you or a ten metre high parabola over the subject.

The second mode, auto framing, is about turning you into a drone film director.

Using the advanced visual tracking algorithms, the Bebop 2 drone consistently keeps its target at centre of frame. The mode has you piloting the drone while its camera works without intervention to adjust the drone’s camera and keep your subject perfectly framed.

dditionally, while managing a stationary flight the drone will readjust on its axis and readjust its camera angle to follow the subject and maintain the framing.

Across both modes of operation the intention seems to be to open up the range of drone filming and give users the ability to film from perspectives that would otherwise be unavailable. The follow me feature seems to sort of act as a third-person Go Pro, giving pilots the chance to film themselves at their most eventful without having to strap a camera to themselves.

The ‘follow me’ feature is currently available for iOS within the FreeFlight Pro application as an in-app purchase for £14.99 after a 15 day trial period. The Android version will be made available in December.

Elon Musk isn't so keen on flying cars

"Obviously, I like flying things, but it’s difficult to imagine the flying car becoming a scalable solution,” Musk told Bloomberg Businessweek. “If somebody doesn’t maintain their flying car, it could drop a hubcap and guillotine you.”

Is the woolly mammoth about to come back from extinction?

Scientists from Harvard University say they are just two years away from creating a hybrid embryo, in which mammoth traits would be programmed into an Asian elephant. The embryo would essentially grow to be an elephant with a number of mammoth traits.

IMAX unveils first virtual reality center

The IMAX VR center, which opened this week, houses 14 different pods, each containing different VR experiences that allow users to temporarily escape real life. One of the pods takes users to the desert planet of Tatooine, which will be familiar to Star Wars fans.

Dwarf planet Ceres emerges as a place to look for life in the solar system

Pockets of carbon-based organic compounds have been found on the surface of Ceres. The identity of the tar-like minerals have't been precisely identified, but their mineral fingerprints match the make-up of kerite or asphaltite.

Beyond biomimicry: Scientists find better-than-nature run style for six-legged robots

Researchers have found a running style for six-legged robots that significantly improves on the traditional nature-inspired method of movement.

The research, conducted by scientists at the École Polytechnique Fédérale de Lausanne (EPFL) and the University of Lausanne (UNIL) in Switzerland, found that as long as the robots are not equipped with insect-like adhesive pads, it is faster for them to move with only two legs on the ground at any given time.

Robotics has in the past few years made heavy use of biomimicry – the practice of mimicking natural systems – resulting in six-legged robots being designed to move like insects. In nature, insects use what is known as a tripod gait, where they have three legs on the ground at a time, so it had been assumed that this was the most efficient way for similarly legged robots to move.

However, by undertaking a series of computer simulations, tests on robots and experiments on Drosophila melanogaster – better known as the common fruit fly – the scientists found that the two-legged approach, which they have dubbed the bipod gait, results in faster and more efficient movement.

The core goal of the research, which is published today in the journal Nature Communications, was to confirm whether the long-held assumption that a tripod gait was best was indeed correct.

“We wanted to determine why insects use a tripod gait and identify whether it is, indeed, the fastest way for six-legged animals and robots to walk,” said Pavan Ramdya, study co-lead and corresponding author.

Initially, this involved the use of a simulated insect model based on the common fruit fly and an algorithm designed to mimic different evolutionary stages. This algorithm simulated different potential gaits to create a shortlist of those that it deemed to be the fastest.

This, however, shed light on why insects have a tripod gait – and why it may not be the best option for robots. The simulations showed that the traditional tripod gait works in combination with the adhesive pad found on the ends of insects’ legs to make climbing over vertical surfaces such as rocks easier and quicker.

Robots, however, are typically designed to walk along flat surfaces, and so the benefits of such a gait are lost.

“Our findings support the idea that insects use a tripod gait to most effectively walk on surfaces in three dimensions, and because their legs have adhesive properties. This confirms a long-standing biological hypothesis,” said Ramdya. “Ground robots should therefore break free from only using the tripod gait”.

To for always corroborate the simulation’s findings, the researchers built a six-legged robot that could move either with a bipod or tripod gait, and which quickly confirmed the research by being faster when moving with just two legs on the ground at once.

However, they went further by confirming that the adhesive pads were in fact playing a role in the insect’s tripod movement.

They did this by equipping the fruit flies with tiny polymer boots that would cover the adhesive pads, and so remove their role in the way the insects moved. The flies’ responses confirms their theory: they began moving with a bipod-like gate rather than their conventional tripod-style movement.

“This result shows that, unlike most robots, animals can adapt to find new ways of walking under new circumstances,” said study co-lead author Robin Thandiackal.

As bizarre as the research sounds, it provides valuable new insights both for roboticists and biologists, and could lead to a new standard in the way that six legged robots are designed to move.

“There is a natural dialogue between robotics and biology: Many robot designers are inspired by nature and biologists can use robots to better understand the behavior of animal species,” added Thandiackal. “We believe that our work represents an important contribution to the study of animal and robotic locomotion.”
