missile with no threat to america. this has been the first missile launch by north korea since donald trump took office. the american president held a joint press conference with japanese prime minister shinzo abe. mr abe said the missile launch was absolutely intolerable and mrtrump said he stood by japan. clashes in the iraqi capital baghdad have left at least five people dead. the trouble broke out between the security forces and supporters of the shia muslim cleric muqtada al—sadr. tens of thousands of demonstrators at the rally denounced government corruption and demanded electoral reform. now on bbc news, it's time for click. this week, swan eats fish, cat ignores mouse, and mountain moves man. few things say the future

better than robots. we seem to be in an era of massive advances at the moment. this week, a leaked video from boston dynamics shows off its latest machine, called handle, something its founder described as "nightmare—inducing". rolling on with the wheel theme, piaggio, known for its vespa motorcycles, has revealed a new robot servant called gita. this robo—suitcase follows its owner's every move, using cameras in its body and in the user's belt. but sometimes it's good to look

at where we've come from. the robots exhibition at london's science museum is a 500—year history of humanity's attempts to create robots that resemble us and our behaviours. there are more than 100 robots here, including some old friends that we've met before. and this amazing swan, made from silver, is all the more incredible because it was made over 200 years ago, in 1773. it's incredibly fragile inside. one of the issues is, how do you get a machine that old to work. so we've had two weeks of highly esteemed conservation colleagues piecing things back together. how does it work? what's inside? you've got a whole series of these silver rings, almost stacked one on top of the other. they are designed to move as it moves as well. the earliest robots worked in a kind of clockwork fashion.

yes, clocks are the earliest self—regulating devices, so they're robots effectively. if you accept that these clockwork creations are indeed robots, then you can also argue that the earliest robots were clocks. it was these mechanical marvels that made the industrial revolution possible, mobilising hundreds of workers to be at the same place at the same time, enabling goods to be transported, trains to run accurately, and allowing industry to become change across the world, bringing about the rise of the working class, and sparking ideas like capitalism and marxism. now, in the west, cuba found itself at the epicentre of this shift. it was the poster child for communism in the west, right in the back garden of the us, the heart of capitalism. richard taylor has been to cuba

to see how the island is now moving with the times. the iconic images are strikingly familiar. cuba today still feels in some ways otherworldly, stuck in a 50s time warp. life for most of its 11 million citizens is simple. they've been living in a state—enforced digital wilderness. a decade ago, you needed a permitjust to buy a pc. today, if you're lucky enough to own a smartphone, chances are it's offline. there's no mobile data, so cuban apps are designed to work without a connection. until recently, even basic internet access could only be found at desktop computers inside state communication centres. long queues persist but now people are coming to buy internet scratchcards which can finally get them online elsewhere.

in this havana park, small gatherings of cubans are all enjoying the internet. but getting online is slow, unreliable and, perhaps unsurprisingly, censored. luis rondon paz is a self—proclaimed hack—tivist, and as a former government it administrator, knows the system well. everything in cuba is restricted, filtered, as the rest of the world. basically, they censor everything that might threaten government power. it might be porn, gay, or political things. basically, most political things. but the biggest barrier for locals — the price. a single hour of full web access costs $2, three days‘ salary. they don't have the time to see what's the internet, really, because of the price of the internet. and they push them to do what they need to do, which is facebook, communicate with their families and make a free phone call.

the government says expanding the internet is a priority and central havana is now conducting trials of in—home net access for 2,000 properties. and it boasts of a growing number of public wifi hotspots, too, around 300 in total, and growing. still, not exactly blanket coverage for a country 700 miles wide. cuba blames its ageing communications network on the six—decade—old trade embargo with the us. critics say that's a convenient excuse for a communist state that fears losing control over information. relations with america are now at best uncertain in the post—0bama era. in the aftermath of the president's historic visit here two years ago, prospects for american companies doing digital business on the island have improved. amongst them, google. company boss eric schmidt inking a deal in december that gives cubans

fast access to content from services like youtube and gmail. the thing is, when you're running an internet—based business, the last thing you want to do is traipse across town to find a connection. so some cubans who are fed up with the government strategy on access have come up with their own rather inventive solutions. the results are found on rooftops in towns and cities across the nation in the form of pole—mounted antennaes which are pointed towards the local communications centre, giving them internet access and even wifi. the practice isn't exactly legal but as i discovered that minor detail doesn't deter cubans from getting their information fix. this is the paquete semanal, literally the weekly packet. it refers to a highly organised service in back streets and front rooms across the country, giving locals content downloaded often only hours earlier via satellite. there's pirated movies, news shows, documentaries, dramas, magazines and mobile apps. it's hugely popular with customers who can fill their usb drives with an entire terabyte,

hundreds of hours, for the price of a single hour online. and the rise of the paquete is the price the cuban regime itself is paying, a reaction to the state dogma of keeping its people restricted. cuban authorities should be less afraid of the free flow of information because the need for information functions as a hunger. people need information and people will get information, no matter if you are going to provide it or not. there's a political need to understand differently what internet means. progress is undoubtedly too slow for many cubans. but recent overtures do at least give some people here cause for hope. hello and welcome to the week in tech. it was the week that samsung's chinese factory supplying batteries for the ill—fated galaxy note 7 suffered a blaze. luckily no one was hurt. twitter announced its new anti—abuse

policy, which will introduce safe search, collapse potentially troubling replies and aims to prevent abusive accounts being reopened. and youtube is launching live video streaming from their mobile app but only for channels with over 10,000 subscribers. uber have employed a former nasa engineer and are working on a flying car. yes, a flying car, that they say could be ready in five years. although there are a few obstacles to overcome, like the authorities allowing them to actually fly. we've seen a few ideas of how to take quad copter drones out of the sky but here is something for heavier duty drones. project sidearm has been developed by darpa, the pentagon's research wing. it aims to safely grab unmanned aerial vehicles from airspace using a crane type setup. and finally, there's a new way of finding love, by sharing hate. new dating app hater matches users by the things that rile them,

with topics including bad pavement etiquette, rent costs, and even politicians. i'm sure that first date will be a laugh a minute! there are plenty of friendly faces at the robots exhibition at london's science museum. there are some which are different enough to look unthreatening and lovable. and there are some, well, some really quite unnerving. currently, the european commission is considering the ethical issues switch, whether they should have rights, and whether they should be considered as electronic persons. and what about those ethical, or even life or death decisions? this is a representation of an experiment in which one robot was programmed to save one of two smaller bots from falling

down a hole. if one was in more danger than the other, their big brother would save it. however, if both smaller robots were equally in danger, big bro would often freeze with indecision. in that split second where the robot is going, "oh, no, there is an equal chance of both dying, i don't know what to do", something kicks in, in the human brain. we are drawing on our attachment to the things that might need saving. we're drawing on maybe a set of moral beliefs or values. we're not entirely sure what's going on in there but we can do what feels right in that moment. so, for now, robot ethics raise more questions than they answer. but while robots are learning how to avoid causing real harm, some humans seem way ahead in causing virtual harm. in video games at least. sword fighting game for honour

is an unusual medieval mash up which pits knights, vikings and samurais against one another. this is bodiam castle. what better place to come and get hands—on with a video game all about swordplay than here? there's just one thing preventing that from happening, though. at 6ft ‘9, and weighing nearly 30st, icelandic strongman thor is this closest thing the game creators could find to a viking warrior. fans of game of thrones will be familiar with him as sir gregor, better known as the mountain. in order to play the game, it's going to be a case of mark versus the mountain in a series of challenges. the game allows players to assume the role of a range of different characters, from heavy hitting, muscle—bound warriors, to nimble lightweight assassin—type characters. but in the real world,

how important is brute strength? well, if a warrior can't even lift their weapon, how are they going to fight with it? so a test of strength against a guy who competes in the world's strongest man. sure, i can do that. all right. hold on. i've got to hold it here, yeah? right, get into position. fantastic. like this. hold it as long as possible. ok, i think i'm doing all right. straighten your arm. straight. oh, my word. that is really... straighten your arm. come on! hold it. it's gone. excuse me while i go and have a lie down. i think i've pulled something. oh, my word. you captured zone a. next up, combat. medieval warriors didn't have to worry about health and safety. we do, so plastic goggles are on.

fortunately, my opponent is made of straw. my task is to do as much damage to this dummy with this sword as i possibly can. en guard. that's not bad. no good. i'll show you how it's done. so the second round belongs to thor, but i think the tide may turn in round three. thor has bested me in a test of strength and in martial skills. however, this is my arena. welcome to my dojo. so we're going to have a one—on—one duel. his character is, of course, a viking. mine is a medieval knight. the match will be best of five. when it comes to getting hands—on with the game, there's not a chance that the big fella is going to beat me. or is there?

this is not filling me with confidence here. game face. game face on. here we go. this is a bit more like it. the thing about this game is you can'tjust button bash. you won't get very far at all. it's got a very fluid combat system. at the heart of it is matching the stance of your opponent and countering it. you have to think a little bit more tactically. how do you like the taste of them apples? bring it. flipping heck. he did me in about two hits. i've got the upper hand, i've got the upper hand!

i actually won. i will see you, sir, in valhalla. thank you, thor, that was a very challenging game indeed. we are in the middle of nowhere and if i could ask you for one favour, that would be great. can i get a lift back to london? sure, why not? come on, jump on. i had thought of a slightly different sort of lift, but there you go. ever wondered what cats get up to when no one's there? meet roxy and zara, who seemed agreeable to taking part

in some gadget testing. sorry. if you've ever wanted to watch, talk to or even play with your cats when you're not with them, then this could help. once the device is connected to your home wifi, you can login anywhere you can get your phone online. there's a laser game to play, snacks at the tap of an icon, and a function to proudly make and share videos and cat snaps. this rather unusual looking setup works in quite a similar way. there's a camera so you can see the cats remotely. also the ability to give them food wherever you are. plus this toy, which is apparently something that cats might like to play with.

zara and roxy were possibly slightly intimidated by the jolting of the feathery thing, and the app was extremely temperamental, making setup a rather tedious experience. but when it came to the cat reactions, maybe us being there was a distraction for them, so there's a chance the devices could have fared better if they were home alone. i think the food dispenser, if they'd been hungry, might have attracted more interest. they found the whole thing a little bit unsettling. this smart collar has been around a little while now and is available for cats and dogs. it allows owners to keep an eye on temperature, pulse, breathing rate, heart rate variability and even the positions a pet is in, so could be particularly beneficial if there are health concerns or an injury to keep an eye on. don't worry, it's ok.

i know my friend's cats are not willing to wear any sort of collar and i have to say this one is pretty large. look how much bigger than a cat i am, and my activity tracker is only this size, so i can see it could be a little bit intimidating. meanwhile, there seems to be a game of cat and mouse going on here, the latter played by a remote control rodent. although it actually consists of the cat being chased by the mouse, which probably says it all about my day's filming. that was lara, and this is maria, the first blockbuster robot from the ground—breaking 1927 film metropolis. the visual effects in that movie were absolutely stunning, given that it is actually 90 years old. next, we are going to continue our look at some of the visual effects

behind the latest blockbuster movies. we have adam valdes, bafta and oscar nominee, to tell us more about the visual effects he used to bring back to life thejungle book. a lot of people have asked me, "why would you do a movie in the jungle and not just go to the jungle, or some jungle, some set that plays for a jungle"? and i think the real answer is, you can't find the place in reality that we've made, you know. we made something special. every time you see the world injungle book, someone has fabricated plants, trees, the dead twigs and leaves on the floor, all of it. and it's only really when this around around him makes him feel present within it that the magic trick comes off, that you believe that this is just a photograph, that we went somewhere and shot it. so we take a shot like mowgli saying goodbye to his mother and we say, john really wants some sort

of physical contact. it needs to be an intimate moment, their eyes need to be locked onto each other. we can't have a feeling that he's acting to a tennis ball, a stick or some marker. we really need to feel the scene emotionally. you can locate the positions of his hands, the puppet for the mother wolf. and we can track it really carefully in three dimensions with our computer software. that way we make sure the contact is correct, and then we simulate the fur on the mother's neck. and we actually replace the better part of his hand with the digital double of his hand, so that the cg

hand and the cg fur of the mother wolf are actually in the computer together, and when we put our lighting on that and create the final images, they really look connected. the magic trick is blending the hand into his arm. it's easy to focus on the fact that we pulled off two main things, these talking animals that people felt emotions from and this complete 3d world we had to create, and that those two things are really major accomplishments. starting off, i did not know if either of them were going to work. the very first time i combined photography of mowgli with a digital background, the background was grey, not even photo realistic. but it was just seeing an image come together where we had planned a shot, filmed it, brought it home, put it together with the digital world. the kid was walking along this curvy branch. and he looked like he was there. and i thought to myself, "0k, maybe this is going to work". you know, "maybe he's really going to look like he's

in this world". the render power required to generate a movie like this, i think it was 240 million renderer hours, or something like that. which means if it was one computer it would have taken 3000 years, some number like that. these individual frames that you see can be 40, 50, 60 hours on a computerjust rendering one frame. the difference between a video game and our imagery is that the video game uses hardware on your computer to generate in real—time an image. and they are amazing, what they are doing. to go from there, however, to complete fool your brain, fool your eye realism, requires quite a lot more computation, because you're simulating the behaviour of materials and light. and that has come so far in the last five years. i think we'll see more and more imagery where we really start to not be able to tell the difference

between something that's computer—generated and real. and that can be a little spooky in one sense, but it's pretty fascinating for creative people. that was adam valdes on the magic behind the jungle book. and that's it from robots at the london science museum. i'll put a load of photos up on twitter for you to browse through at bbc click. thanks for watching and, yeah... we'll be back. most of the snow that we've seen build up so far over the last 2a

hours has been over high ground. for example, near the pennines and west yorkshire, near leeds, a good covering of snow in the last 2a hours. thanks to our weather watcher for sending that picture. generally a fine line between rain and snow. a lot of what you can see on the charts at the moment is rain coming in, but there is the prospect of seeing a centimetre or two of snow maybe in east anglia and maybe across the hills of central southern england through the night. the chilterns and downs at risk of seeing that. for most of us it will be another grey, cloudy and cold start to the day, quite damp too, with outbreaks of rain at lower levels. across the pennines there will be ongoing heavy snow through sunday morning. we could see up to ten centimetres of snow above 300 metres elevation. some disruptive weather. further west a lot of cloud around.

yes, we will have patches of rain. into the hills of east wales it's more likely we will see a bit of snow here. but for west wales it's a largely dry start, perhaps with a few glimmers of brightness. starting off cloudy, perhaps with patchy rain, sleet over the hills. through the rest of sunday it stays grey and gloomy. the cold wind with us again. temperatures really struggling. the snowiest weather is continuing to affect the pennines, but elsewhere there will tend to be a transition from snow back to rain as we go into the afternoon. the temperature just begin to rise a little bit. highs reaching between 4—6, but feeling colder than that due to the strength of the east, north—easterly winds. rugby union takes place again on sunday. the match between france and scotland probably dry. temperatures about seven degrees, so it should be warmer in france than it is here in the uk. things will get a little bit milder over the next few days, as the wind switches more to a south—easterly direction.

the winds won't be as cold. so overnight sunday night the temperatures not as low for most of us, 3—4 typically for england and wales. still cold enough for a sharp frost in northern scotland. perhaps down to minus five, minus seven here. monday will be especially windy around some of our western coasts and hills. that's something to watch out for. but there should be more sunshine across england and wales. temperatures climbing, but still feeling cold in that easterly wind. further north, grey and gloomy, with patches of rain and drizzle. the trend is that things will turn milder towards the middle part of the week, as we lose the easterly winds. temperatures in london hit 12 by wednesday. welcome to bbc news, broadcasting at home and around the globe. i'm ben bland. our top stories: north korea fires a ballistic missile into the sea ofjapan — the latest military test by pyongyang. side by side with president trump — japan's prime minister says the launch is absolutely
