Human taught Robot to Fight Back

An amazing video of a robot dog fighting off a human as it tries to open a door is not only creepy, but it also has raised the question: Why are we teaching a robot to fight back against humans?

The "dog" in question is the SpotMini, a 66-lb. (30 kilograms) robot designed to fit comfortably in a home or an office. In the video, the dog is shown attempting to open a door—when a human comes with a hockey stick and shoves the robot's grasping arm away from the door knob. The robot manages to open the door anyway, and even continues standing when a human tries to pull "him" away from the door using a huge leash.

It turns out, any successful robot assistant for the home needs to be good at dealing with "disturbances," according to the company ­— and that may sometimes include pesky humans. [Robots on the Run! 5 Bots That Can Really Move]

                

Robot dog

Unlike some of Boston Dynamics' other robots, such as the humanoid Atlas, SpotMini isn't designed to help people in a disaster situation. Instead, he's meant to be a vaguely cute home or office assistant. But that means he actually needs extra capabilities that a disaster robot might not.

For instance, to be useful, a fetching robot would need to be able to pick up objects of different sizes and bring them to its "master," which many battlefield robots aren't designed to do. And the home environment also involves challenges, such as doorways, stairs and slippery obstacles, which earlier versions of the robot struggled with. So far, Boston Dynamics has shown that progressive iterations of SpotMini can do these tasks: The company  has posted videos of this little dog climbing stairs, crawling under tables, loading a dishwasher, filling the trash and bringing someone a Diet Coke.

And of course, many homes have children, who are not known for their restraint when dealing with pets and other moving objects, as this video montage of babies riding Roombas reveals.

Boston Dynamics doesn't explicitly mention the hazards of small children, but its tersely-worded description of the robot in the YouTube video does hint at that type of challenge.

"The ability to tolerate and respond automatically to disturbances like these improves successful operation of the robot," the company wrote in the caption.

Get ready for a 5G Internet of the Sky

By Jamie Carter  World of tech  

Drones like the Ehang 184 will usher in a 5G-powered autonomous airspace

Autonomous cars will need 5G to avoid crashing into each other. But what about drones? Pilots hate drones. Airports hate drones. So do prison guards, wary of the airborne smuggling of drugs, smartphones, and even weapons (no kidding). Drones are evil, bad and need to be banned … that’s been the knee-jerk reaction of some. So, what’s the answer? The mobile phone network, of course.

Tracking drones

Can’t we use radar to track drones? Nope – commercial civilian drones are way too small. Cue the humble 4G SIM card, which the Global System for Mobile Communications Association (GSMA) – the hosts of the Mobile World Congress (MWC) – believes can make drones great again. 

Tracking drones will give them an identity, avoid drone-on-drone collisions, and make drone incursions and misuse impossible at airports and prisons. 

The first ‘drone taxi’

So, something for the mobile industry’s maybe-next-year to-do list? The arrival at MWC 2018 this week of the Ehang 184 is bringing drone regulations and technology into sharp focus. 

Ehang 184 autonomous passenger drone

As we’ve reported on before, this one-seater autonomous aerial vehicle, or ‘drone taxi’ (OK, flying car) should have already begun ferrying people between Dubai’s airport and the city's major hotels. Delayed it may be, but this electric, four-blade drone looks destined to soon become part of ‘the world's most intelligent transportation system'. 

Dubai’s Roads and Transport Authority wants a quarter of all trips in Dubai to be via self-driving vehicles, including by ‘drone taxis’, by 2030. “It’s fully automated, and remotely monitored and controlled by a human operator,” says Andrew Parker, Programme Marketing Director, Internet of Things at GSMA. “The technology in the Ehang 184 will fly itself, but for safety reasons it’s monitored remotely to make sure it’s flying correctly in the right place.” 

Room for one

Parker adds that a two-seater model will be available shortly, so people will have the reassurance of a pilot. People do love some reassurance, and that’s partly what’s behind the GSMA’s plan to network all drones. 

The drone explosion

By 2050, drones will log more than 250 million flying hours per year over densely populated areas of the European Union, according to the Single European Sky Air Traffic Management Research (SESAR) project. That’s seven times the cumulative annual flying hours of conventional crewed aircraft.

Although it may stand-out on the show floor in Barcelona this week, the Ehang 184 will likely be the first of many, many commercial drones of all kinds. “This kind of commercial drone is going to explode in number,” says Parker. “From people-carrying drones to delivery drones to parcel-carrying drones, we’re going to see a huge array of applications.” 

What Parker and the GSMA thinks is required to make the drone era a reality is to address the concerns of governments and regulators head-on. “If we can show that drones have an identity, and if we can put certain controls on drones to keep them away from sensitive places, and from each other, governments will be a lot happier to deploy them,” says Parker. 

There’s already a group in the GSMA looking at the regulatory challenges surrounding the mass-deployment of drones. But the answer is becoming obvious; an Internet of the Sky.

What is the Internet of the Sky?

Though he admits that the Ehang 184 is an extreme example, Parker thinks that to encourage trust in the technology, every drone needs a SIM card inside it. The Ehang 184 already has a network need; it requires 100Mbps upload and download to serve its 4K cameras and LiDAR scanners. 

A SIM means that if a drone drops out of the sky, it will be easy to tell who it belongs to, which is important for liability. “What we are looking at now is tuning the mobile network so we point it upwards as well as down, and by developing mobile networks like this we can use SIM cards for three things,” says Parker. “Drone navigation for crash-avoidance, drone geofencing so they can’t enter sensitive areas, and drone identification so we know the identity of the owner of the drone.” This is the Internet of the Sky. 

Put simply, the Internet of the Sky will require exactly the same technology as autonomous vehicles will

Why drones have a 5G future

“The Internet of the Sky is an entirely new application for mobile networks, but it’s needed because the skies could become crowded, and will need advanced communication,” says Parker. “4G will lead to 5G, allowing decisions to be made much faster for collision avoidance.” Put simply, the Internet of the Sky will require exactly the same technology as autonomous vehicles will. “Mobile networks are uniquely placed to help in this kind of space,” says Parker.

The first drone-tracking trials

It seems he’s right on the money. Exactly what Parker is talking about is about to happen in Europe thanks to Vodafone, which announced last week a trial of the world’s first air traffic control drone-tracking and safety system. 

Obviously it doesn’t yet use 5G, instead using 4G-powered Internet of Things (IoT) tech to develop a Radio Positioning System (RPS) for drones. Using 4G modems and a SIM embedded within each drone, Vodafone’s project enables real-time tracking, operator control, protective geofencing, emergency remote control, and SIM-based e-identification and owner registration.

Trials of Vodafone’s drone tracking and safety tech are scheduled for Spain and Germany through 2018, and it’s planned for commercial deployment next year. “This groundbreaking innovation by Vodafone will help to ensure the skies stay safe as drones become ubiquitous, everywhere,” said Johan Wibergh, Vodafone Group Chief Technology Officer. 

Eyes in the sky

In Barcelona the MWC was also showing a model of an existing fixed-wing drone, the XSun, which has a 4.5m wingspan covered in solar panels. 

Capable of staying in the air for 14 days at a time – cue surveillance and air-sea rescue. “This could find lost people,” says Parker. “All you need is connectivity and you could keep it in the air for a very long time,” he says, stressing how much better a solution drones are than launching satellites. “You get a better view, better video, it’s cheaper, and you get a much lower footprint … it’s an eye in the sky that runs itself.”

MWC (Mobile World Congress) is the world's largest exhibition for the mobile industry, stuffed full of the newest phones, tablets, wearables and more.

Arsenal Hambar

3 Pemain Terburuk Arsenal Musim Ini

Momen saat Arsenal kehilangan gelaran Piala Liga Inggris 2017/2018 setelah dikalahkan Manchester City 3-0.

      Satu kesempatan bagi Arsenal untuk meraih gelaran juara di musim 2017/2018 telah hancur. Ini kerana The Gunners tumpas 0-3 di tangan Manchester City saat menyertai final Piala Liga Inggris di Wembley Stadium.

Pada pertandingan tersebut, Arsenal bolos  tiga gol tanpa balas dari Manchester City. Tiga gol The Citizens disempurnakan oleh Sergio Aguero di minit ke-18, Vincent Kompany ke-58, dan David Silva ke-65.

Padahal, Piala Liga Inggris adalah salah satu dari dua kompetisi yang paling mungkin dijuarai Arsenal. Itu karena kesempatan mereka di dua pertandingan lain sudah nyaris tertutup. Di Piala FA, mereka sudah dikalahkan Nottingham Forest di babak ketiga.

Di Liga Inggris, Arsenal tak tersenarai dalam 4 pasukan teratas. Sampai saat tim didikan Arsene Wenger itu masih tertahan di kedudukan keenam, terpaut 10 poin dari urutan keempat. Keterpurukan mereka pun tak lepas dari penampilan buruk beberapa pemain.
Menurut Liputan6.com, setidaknya ada tiga pemain yang penampilannya di musim ini gagal memenuhi ekspektasi. Hal itu yang menjadi penyebab mereka gagal tampil kompetitif di semua kompetisi.

---

1. Alexandre Lacazette

Penyerang Arsenal, Alexandre Lacazette gagal memenuhi ekspektasi di musim ini.

Ekspektasi Arsenal kepada Lacazette jelas sangat besar. Apalagi, Arsenal harus merogoh kocek hingga 53 juta euro untuk membelinya dari Olympique Lyon pada musim panas 2017. Tingginya nilai Lacazette jelas sangat wajar.
Selama di Lyon, pemain asal Prancis itu memiliki jumlah gol yang memukau di setiap musim. Sejak musim 2013/2014, minimal ia mampu menyumbang 22 gol dalam semusim. Bahkan, di musim 2016/2017 ia bisa melesakkan 37 gol.
Anehnya, Lacazette tak mampu mengulangi penampilan terbaiknya di musim ini. Meski sudah dimainkan dalam 29 pertandingan, baru sembilan gol dan empat assist yang disumbangkan pemain berusia 26 tahun tersebut.

2. Shkodran Mustafi

Pemain Manchester City, Kevin De Bruyne berebut bola dengan pemian Arsenal, Shkodran Mustafi dalam laga final Piala Liga Inggris di Stadion Wembley, Minggu (25/2). Manchester City menghancurkan Arsenal dengan skor telak 3-0.

Salah satu penyebab keterpurukan Arsenal di musim ini juga tak lepas dari buruknya sistem pertahanan mereka. Di Liga Inggris, mereka menjadi tim dengan jumlah kebobolan terbanyak di antara penghuni tujuh besar.
Dalam 15 pertandingan terakhir di semua kompetisi, gawang Arsenal hanya dua kali terhindar dari kebobolan. Alhasil, mereka juga hanya bisa mengukir empat kemenangan dalam 15 laga terakhir.
Salah satu bek dengan penampilan mengecewakan adalah Mustafi. Padahal, bek berusia 25 tahun itu dianggap memiliki potensi besar. Ia juga sudah menjadi bek andalan Timnas Jerman. Sayang, dari 23 penampilan di musim ini, ia gagal menciptakan kolaborasi hebat bersama Laurent Koscielny.

3. Mesut Ozil

Pemain Arsenal, Mesut Ozil.

Menyandang gelaran sebagai salah satu pemain tengah terbaik di dunia, penampilan Ozil justeru tak konsisten sepanjang musim. Terkadang, ia mampu tampil memenuhi ekspektasi, tapi tak jarang pula performanya sangat mengecewakan.
Padahal, Ozil menanggung harapan besar dari segenap pendukung Arsenal. Terlebih, gelandang Timnas Jerman itu juga telah memperpanjang kontrak yang akan membuatnya tinggal di London hingga Juni 2021.
Secara keseluruhan, Ozil sudah melakoni 25 pertandingan di semua kompetisi. Kontribusinya hanya berupa torehan lima gol dan tujuh assist. Musim lalu, Ozil mengoleksi 12 gol dan 14 assist dari 44 laga.
