:00:00. > :00:00.Hi, everyone. You're live with me, Leah, and on today's Newsround,
:00:00. > :00:10.we're looking at how robots will change the way we live at home.
:00:11. > :00:11.And the amazing story of how elephants can tell the difference
:00:12. > :00:21.between human languages. First, it's straight to the slopes
:00:22. > :00:23.of Sochi, where after her gold medal in the super-G yesterday, Kelly
:00:24. > :00:27.Gallagher took a tumble today midway through the slalom event of the
:00:28. > :00:33.super-combined, and couldn't add to her medal tally. Conditions were
:00:34. > :00:35.tricky for all skiers, but team-mate Jade Etherington, who finished
:00:36. > :00:41.fourth, was promoted to second after another skier missed the final gate.
:00:42. > :00:44.It means if Jade does well in Friday's super-G event, she'll be
:00:45. > :00:47.guaranteed her third medal of the Games.
:00:48. > :00:51.Next, they say an elephant never forgets. Now researchers have shown
:00:52. > :00:54.just how much they remember. Scientists reckon just by hearing a
:00:55. > :00:57.voice, African elephants can tell men from women, adults from kids,
:00:58. > :01:03.and even tell the difference between our languages. Martin has more.
:01:04. > :01:06.Just how intelligent is an African elephant? Researchers in Kenya's
:01:07. > :01:13.National Park used a camouflaged loudspeaker to play the same phrase
:01:14. > :01:18.in different voices and languages. CHILD SPEAKS IN FOREIGN LANGUAGE.
:01:19. > :01:22.They found that elephants were more frightened and moved away from the
:01:23. > :01:26.sound of adult men, who were more likely to be hunters, rather than
:01:27. > :01:30.women or children. To protect themselves, elephants get into a
:01:31. > :01:33.tight group - babies in the middle right up with their grandmother -
:01:34. > :01:38.and you see them putting their trunks up to check by smell who is
:01:39. > :01:41.out there. They can also tell the difference between the dialects of
:01:42. > :01:44.different tribes. They reacted when they heard the language of the
:01:45. > :01:47.Maasai cattle-rearing tribe, who they compete with for land, food and
:01:48. > :01:54.water, but remained still for other tribes they don't come into conflict
:01:55. > :01:57.with. These gentle giants may be known for their memory, but it turns
:01:58. > :02:01.out they are pretty good listeners too.
:02:02. > :02:05.Next, we're talking robots. You've already sent us loads of amazing
:02:06. > :02:09.robot designs - too many to mention here - but check them out on the
:02:10. > :02:10.website. Today in our special series, Ricky checks out how robots
:02:11. > :02:23.could change our lives at home. This may look like a normal house on
:02:24. > :02:25.the outside, but what is going on inside could change the way we live
:02:26. > :02:32.our lives in the future. ROBOT: Hello, Ricky. Welcome to the
:02:33. > :02:44.robot house. This property in Hertfordshire comes
:02:45. > :02:50.with two robots that are programmed to help us out with everyday tasks.
:02:51. > :02:54.There are lots of sensors in this house. They are in the sofa, in the
:02:55. > :02:57.cupboards, on the doors, in the microwaves. They are all over the
:02:58. > :03:00.place. They are also on the ceiling, and detecting our every single move,
:03:01. > :03:04.our daily habits, where we spend most of our time, and it is feeding
:03:05. > :03:08.all that information into the computer. We have indeed more than
:03:09. > :03:13.60 sensors here, which is quite a lot. What we try to do is find out
:03:14. > :03:16.what a person is doing, and then use the technology we have here, with
:03:17. > :03:20.the robots included, trying to help the person - reminding the person of
:03:21. > :03:28.certain appointments, or to call a friend. So this is the type of help
:03:29. > :03:34.that we have in mind. The sensors are in tune with this computer here.
:03:35. > :03:39.We can see the layout of the house. If somebody opens the microwave, we
:03:40. > :03:44.will see the colour change. It's gone red. It's gone red. Perhaps if
:03:45. > :03:47.it was open for too long, it might alert us to close the door. Yes,
:03:48. > :03:50.absolutely. This technology might also allow old people to stay in
:03:51. > :03:54.their homes for longer. The robots can remind them when to take their
:03:55. > :04:00.medicine, and even when to watch your favourite TV programme. Please
:04:01. > :04:05.remember to watch Newsround. Time for me to put this house to the
:04:06. > :04:10.test. I'll see you in the morning. And head to the website to see how
:04:11. > :04:14.Ricky got on in the robot house. And there's a gallery of your robot
:04:15. > :04:22.designs, from the brilliant Norbat 5000 with fire alarm ears, to one
:04:23. > :04:27.that uses sensors to catch robbers! Now to New Zealand, where a vote is
:04:28. > :04:30.set to take place over whether to change their national flag. As you
:04:31. > :04:34.can see, it currently has a Union Jack - the UK's national flag - in
:04:35. > :04:37.the corner. Their Prime Minister says this is out of date, as the
:04:38. > :04:41.design represents a time when New Zealand was under British rule. One
:04:42. > :04:45.idea is to change it to the white fern, used by their national sports
:04:46. > :04:49.teams. Head to the website, where you can
:04:50. > :04:53.find out how countries design the flags that represent them.
:04:54. > :04:56.I'm out of time. See you at 6:50, where we'll see how Ricky's got on
:04:57. > :05:01.in the robot house!
