is going to feel colder and there is milder weather on the horizon. more on that in half an hour. sport now, and for a full round up, from the bbc sport centre, here's mike bushell. we have just been watching your antics in snowdonia. amazing fun in the end. lots of fun ahead in the rugby union, one of the biggest days in the six nations calendar, as wales try to take england down to size, and our correspondent is at the municipality stadium. so much in this build—up has been about eddiejones and his comments, but it is a massive occasion for wales, isn't it? really good point. we have got the

trophy here. i thought we would use that to point out that it is a six sided redesigns trophy, and all six sides do have a chance of lifting it. if ireland lose in italy this afternoon, their chances have gone. eddiejones, so afternoon, their chances have gone. eddie jones, so much afternoon, their chances have gone. eddiejones, so much the talking point in the build—up. he knows what he's doing, he is so experienced. he makes his comments to take the pressure off his players. rob howley, far less experienced. this is an experience for him to show that he is the permanent welsh coach. we will hear from that he is the permanent welsh coach. we will hearfrom him in a moment. all the focus and history in the build—up to this game. england came here last year with an inexperienced side and came back to win. there are some elements of that tea m win. there are some elements of that team who will be playing this afternoon, notably george ford at fly—half. it was a good night for us. we

managed to come away with a great result. it was a great place to play, and as a player, you would back on games like that —— look back, and they stick out in your memory. and building up to it like this, you can only be excited about it. they have gone 15 games unbeaten, they play with confidence, a huge amount of self belief, and they have got across the line against france. i think that in the first games of the weekend, there is a rustiness about you, and certainly we saw elements of that. but i have no doubt that they will be ready for this game. if you are a fan of welsh rugby union, this might be a moment for a few seconds to cover your eyes and ears. we will bring you date with the women' international. england at

half—time were winning by 38—0. we should remember that england for the first time going to this six nations isa first time going to this six nations is a fully professional female team, and that extra concentration, fitness, skill certainly showed in the first—half. it is an artificial pitch, giving an opportunity for fast flowing, free running rugby. some of their tries coming from the wing. interesting, being professional must make the world of difference will stop. to football, and there is confusion over the future of the latest rangers manager, mark warburton. rangers issued a statement that he had resigned, at warburton says he was not aware of

that and is consulting his legal team. rangers are playing morton tomorrow in the scottish cup, and the under 21 coach is leading rangers. celtic are playing inverness today, and it is currently goalless. and dundee are playing kilmarnock. in the english premier league, arsenal zero, kilmarnock. in the english premier league, arsenalzero, hull kilmarnock. in the english premier league, arsenal zero, hull city zero. that is all the sport for now, it is time for click now on bbc news. this week, swan eats fish, cat ignores mouse, and mt moves mt. —— 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 it's founder described as nightmare inducing. rolling on with the wheel thing, piaggio has revealed a new robot servant. this robotic suitcase follows at owners' every move using cameras in its body and the user's belt. sometimes it is good to look where we have come from. the robot 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 have met before. and this amazing swa n have met before. and this amazing swan made from silver is all the more incredible because it was made over 200 years ago in 17 73. it is incredibly fragile inside. we have had two weeks of conservation collea g u es have had two weeks of conservation colleagues piecing things back together. what you have got is a whole series of the silver rings, stacked on top of the other, they are designed to move as well. the earliest robots worked in a kind of clockwork fashion. yes, cox worked in a self—regulating fashion, so they are robots effectively —— clocks. you could also argue that the earliest robots were clocks. it was

these mechanical marvels that made 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 an efficient machine. the industrial revolution was also the catalyst for massive social change across the world. bringing about the rise of the working class and sparking ideas like capitalism and marxism. 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 have been living in a state enforced digital wilderness. a decade ago you needed a permit just digital wilderness. a decade ago you needed a permitjust about digital wilderness. a decade ago you needed a permit just about a digital wilderness. a decade ago you needed a permitjust about a pc. today if you're lucky enough to own a smartphone, the chances are it is off—line. there is no mobile data so local cuban apps are designed to work without connection. until recently, even basic internet access could only be found in desktop computers inside state communication centres. long queues persist, but people are coming to buy internet scratchcards, which can finally get them online elsewhere. in this havana park, small gatherings of cu ba ns havana park, small gatherings of cubans are enjoying the internet. but getting online is slow, unreliable, and perhaps unsurprisingly, censored. this man

isa unsurprisingly, censored. this man is a self—proclaimed activist, and asa is a self—proclaimed activist, and as a former government it ministry to, knows the system well. everything in cuba is restricted. it might be pawn, or political. it is mostly political things. the biggest barrierfrom locals is the price. a single hour of web access costs $2, three days' salary. they do not have the time to see what is the internet, because of the price of the internet, and they push them to do what they need to do, which is facebook, communicate with families, and a foam core. the government says expanding the internet is a priority in central havana. it boasts of a growing

number of public wi—fi hotspots, around 300 in total and growing. still, not exactly blanket coverage for a country 700 miles wide. cuba blames it ageing mean occasions network on the six decade old trade embargoes the us. critics say that asa embargoes the us. critics say that as a convenient excuse for a communist state that fears losing control over its mission. relations with america are now at best uncertain in the post—0bama era. in the aftermath of the president's historic visit to years ago, the prospects for american companies doing digital business on the island have improved. amongst them, google, and company boss eric schmidt inked and company boss eric schmidt inked a deal in september that gives cu ba ns faster access to a deal in september that gives cubans faster access to content from services like youtube. when you're running an internet business, the last thing you want to do is trade is half way across town to find a connection. some cubans are fed up, and have come up with inventive

solutions. the result is to be found on solutions. the result is to be found o n roofto ps solutions. the result is to be found on rooftops in towns and cities across the nation. pole mounted antennas which appointed towards the local communities and centre, bring them internet access and even wi—fi. the practice is not exactly legal, but that minor detail does not deter cu ba ns but that minor detail does not deter cubans from getting their information fix. this is literally the weekly packet, referring to a highly organised service in backstreets and front rooms across the country, giving locals content downloaded of —— often only hours earlier via satellite. it is hugely popular with customers, who can fill their usb drives with an entire tera byte, their usb drives with an entire terabyte, hundreds of hours, for the price of a single hour online. and the rise of this 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, because the need for information, it is a hunger, people need information and people will get information no matter if you're going to provide it or not. there is a political need to understand differently what the inference —— intranet meet —— intranet means. recent overtures to at least give some people here cause for hope. welcome to the week in tech. factory supplying batteries for the galaxy seven suffered a blaze. safe search, potentially troubled replies being quashed, and youtube launching live streaming from their mobile app.

goober have employed a former nasa engineer, and they are working on a flying car. they say it could be ready in five years, although there area ready in five years, although there are a few obstacles to overcome, like the authorities allowing them to actually fly. we have seen a few ideas of how to take quad copter drones out of the sky, but here are some things are heavier duty drones. project sidearm has been developed by the pentagon's research wing. it is to grab unmanned vehicles from space. finally, there is a new way of finding love, by shearing —— schering hate. it matches users by topics that rile them, including bad pavement etiquette, rent costs, and even politicians. that first date will be a laugh a minute! there are plenty of friendly faces

at the robot exhibition at london's science museum. there are some which are different enough to look threatening and lovable. —— unthreatening. and there are some, some which are really quite unnerving. currently, the european commission is considering the ethical issues that robots raise, including whether they should have a kill switch, whether they should have rights, and whether they should be considered as an electronic person. and what about those ethical, or even life or death decisions? this is a representation ofan decisions? this is a representation of an experiment in which one robot was programmed to save one of two smaller robots from falling down a hole. if one was in more danger than the other, then big brother would save it. however, if both smaller robots were equally in danger, big

brother would often freeze with indecision. in that split second, where the robot is going, 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 make —— might need saving, we are drawing on maybe a set of moral beliefs or values, we are not entirely sure what is going on, but we can do what feels right. so, for now, robot ethics raise more questions than answers. but while robots are learning how to avoid causing harm, some humans seem more ahead in causing virtual harmony video games at least. sword fighting game for honour is an unusual mash up game for honour is an unusual mash up which pits vikings, romans and samurais against each other. this

castle is the best place to come to get your hands on the video game all about swordplay. there isjust get your hands on the video game all about swordplay. there is just one thing preventing that from happening, though. at six foot nine, and weighing 30 stone, this icelandic strongman is the closest thing the game creators could find toa thing the game creators could find to a viking warrior. fans of game of thrones will be familiar with him as the mt. in order to play the game, it is going to be up case of mark versus the mountain in a series of challenges. the game allows you to play a different series of characters. but in the real world, how important is brute strength? if i warrior cannot even lift their weapon, how are they going to fight with its question at a test of strength against a guy who competes in the world strongest man. sure, i

can do that. let's get into position. hold it as long as possible. street in neurons. —— straighten your arm. come street in neurons. —— straighten yourarm. come on! hold it, come on! excuse me while i go and have a lie down, i think i have pulled something. you captured zona a. next up, combat. medievalwarriors did not have to worry about health and safety. fortunately, my opponent is made of straw. my task is to do as much damage to this dummy with the sword as i possibly can. 0n guard! that's not bad.

i will show you how it is done. so the second round belongs to the mountain, but the tide may turn with round three. this is my arena, welcome to my dojo. we're going to have a one—on—onejewel, his character is of course a viking. mine isa character is of course a viking. mine is a medieval knight. the match will be best—of—5. when it comes to getting hands—on with the game, there is 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. he we call, this is a bit

more like it. —— here we go. the thing about this game, you cannot just button bash. the thing about this game, you cannotjust button bash. it has 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. 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, that was a

very challenging game indeed. we are in the middle of nowhere, and i could ask you for one favour, can a lift back to london? sure, why not? jump on. that is a slightly different sort of lift, there you go. ever wondered what cats get up to when no one is there? meet roxy and zara, who seemed agreeable to taking pa rt zara, who seemed agreeable to taking part with some gadget testing. sorry! if you have ever wanted to watch, talk to, or even play with your cat

when you're not with them, then this could help. 0nce when you're not with them, then this could help. once the device is connected to your home wi—fi, you can login via the app anyway you can get your phone online. there is a laser game to play, snacks at the top ofan laser game to play, snacks at the top of an icon, and the function to proudly make and share videos and cat snaps. this rather unusual looking set up works in quite a similar way. the is a camera so you can see the cat remotely, also the ability to give them food wherever you are, plus this type which is apparently something that cats might like to play with. zara and roxy were possibly slightly intimidated by the jilting of the feathery thing, and the app was extremely temperament,

making set up a rather tedious experience. but when it came to the cat‘ reaction, maybe as being there was a distraction for them, so there isa was a distraction for them, so there is a chance the devices could have fared better if they were home alone. the food dispenser, if they had been hungry, might have attracted more interest. i think they found the whole thing a little bit unsettling. the smart collar has been allowed a little while now, and is available for cats and dogs, allowing owners to keep an eye on temperature, pulse, breathing rate, heart rate variability, and even the position the pet is in, so it 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 friends' cats are not willing to wear any sort of colour, and this one is actually pretty large. look at how much bigger than a cat i am, and my activity tracker is only the

size. i can see how it can be a bit intimidating. meanwhile, there seems to be a game of cat and mouse going on here. the latter played by a motor control rodent. although it actually consists of the mouse chasing the cat, which probably says it all about my day's filming. that was lara, and this is maria. the first to post a robot from the ground—breaking 19 —— 1927 film, metropolis. all the more astonishing because that film is 90 years old. we're going to continue our look at some of the visual effects behind the latest blockbuster movies. adam is here to tell us more about the visual effect he used to bring back to life thejungle book. a lot of people have asked me, why

would you do a movie in thejungle, and not just would you do a movie in thejungle, and notjust go to the jungle or somejungle, and notjust go to the jungle or some jungle, sunset that plays through jungle? and i some jungle, sunset that plays throughjungle? and i think the real a nswer throughjungle? and i think the real answer is, you cannot find the place in reality that we made. we made something special. every time you see the world in thejungle book, someone has fabricated planted trees, the dead twigs and leaves on the floor, all of it, and it is only when the surround around mowgli makes him feel present and in it, that the magic trick comes off, that you can believe that this is just a photograph. we ta ke photograph. we take a shot like mowgli saying goodbye to his mother, and we say, ok, goodbye to his mother, and we say, 0k,john goodbye to his mother, and we say, 0k, john really wants some sort of physical contact, it needs to be an intimate moment, their eyes need to be locked into each other, we cannot

have a feeling that he is acting to a tennis ball on a stick or some sort of marker. we need to feel the scene emotionally. we can locate the positions of his hands, the puppet for the mother wolf, and we can track it very carefully in three dimensions with our computer software. that way, we make sure the contact is correct, then we simulate the further on the mother's neck, and we actually replace the better pa rt and we actually replace the better part of his hand with a digital double of his hand. so that the cg! and at the cg! fur of the mother wolf are in the computer together, and when we put the lighting on that we create the final images, and they look connected, and the magic is blending the hand into mowgli's arm. it is easy to focus on the fact that we put off two main things, talking

animals that people felt emotions from, and this complete 3—d world we had to create, and that those two things were the major accomplishments. starting off, i did not know the if you —— either of them were going to work. it was the very first time i combined photography of mowgli with a digital background, and the digital background, and the digital background was just great, it was not photorealistic. 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, like he was there. and i thought to myself, ok, maybe this is going to work. maybe he is really going to look like he is in this world. the render power required to generate a movie like this, i think it was 240 million render hours, something like that. which means if it was one

computer, it would have taken 2000 yea rs, computer, it would have taken 2000 years, some number like that. these individualframes years, some number like that. these individual frames that you see can be 40, 50, individual frames that you see can be 40,50, 60 individual frames that you see can be 40, 50, 60 hours individual frames that you see can be 40,50, 60 hours on a computer, just rendering one frame. the difference between a video game and our imagery is that the video game is hardware on your computer to generate in real—time and image, and they are amazing, what they are doing. to go from there to complete filling your brain, your eye, realism, requires quite a lot more computation because you're simulating the behaviour of materials and late, and that has come so far in the last five years that i think we will see more and more imagery where we really start to not really be able to tell the difference between something that is computer—generated and real, and that can be little spooky in one sense, but it is fascinating for creative people. that was adam valdes on the magic

behind the jungle book. that was adam valdes on the magic behind thejungle book. and that is it from robots at the london science museum. i will put photos up on twitter for you to browse through. thanks for watching, and, yes! look out the window, and this is what you will have for the rest of

saturday. 0utbreaks what you will have for the rest of saturday. 0utbrea ks of what you will have for the rest of saturday. outbreaks of rain, sleet and snow around. some of us getting blues guys, —— blue skies. temperatures just a few degrees above freezing, factor in the wind and get stronger through the weekend, it feels even colder. tonight, it is a similar picture. 0utbreaks tonight, it is a similar picture. outbreaks of rain, sleet and snow. snow piling up in the highest ground of the pennines and the peak district. a few centimetres elsewhere. going into sunday morning, the lowest bridges overnight, —— temperatures, severe frost in parts of scotland. 0utbreaks is —— of sleet and rain and snow. it will not feel any warmer, particularly as the wind tomorrow stronger. good afternoon. president trump says he may rewrite his travel ban, after his initial attempt to bar travellers from seven mainly muslim countries was blocked by the courts. but he said he hasn't ruled out an appeal to the supreme court over his original directive.

it's unclear what his new immigration plan might look like. david willis sent this report. after a federal appeals court backed a stay of his executive order,
