Hi, I'm Ayshah with Friday's Newsround.

Track and field athletes from Russia will be banned from competing

Russia is one of the most successful countries

in Olympic history, having won hundreds

But they won't be adding to their medal tally this summer

in Rio - the country's track and field team aren't allowed

to compete in the Olympics because lots of them

They have been found guilty of doping.

That's when people use banned drugs to cheat and give themselves

The Russian Olympic Committee and 68 athletes argued against a decision

to ban them by the organisation that runs world athletics.

Things could get worse for all of Russia's sports men and women.

There are calls to ban all the country's teams

from the Games, as experts look into whether or not other athletes

The Canadian superstar Drake is heading towards his 15th week

While Drake might be celebrating, others in the music industry say

it's a sign that the charts are broken.

But Drake has been hogging the limelight for three months.

He's already spent 14 weeks at number one

and is set to draw level with a 1994 song by Wet, Wet, Wet

Although Drake's song has been on top for so long

he hasn't actually sold that many records, it's streaming that

I've come to Radio One to meet Chris Price,

whose the man in charge of what music goes on the station.

What has changed recently to make Drake stay longer than he would have

done? Until recently the chart only measured the number of people buying

a single, for example from a download store. Now the chart

include streams. So it is like someone following you home and

counting how many times you listen to a song in your bedroom. What does

that mean for radio one? There might come a point where we are ahead of

the charts and we might have to take Drake of the playlist. That is a

serious question we have to ask ourselves at the moment. Have you

ever seen anything like this? I don't think it has. If we took Drake

of the playlist while he was number one bout with new thing.

So will Drake be around for one more dance?

Sometimes you can have too much of a good thing.

Now to a show all about robots fighting each other.

Robot Wars sees viewer's homemade robots up against the show's

own house robots, like this one behind me.

The new series starts on Sunday so I went to speak to the show's

producer to find out what's in store.

Andrew, we're at the press launch of Robot Wars.

It felt like a secret that we have been holding for a long time.

Tell us about what it was before and what you have now.

Back in the day, you can imagine the size of a computer

or a TV ten years ago, they were massive and old.

Technology has changed so much, they are so much more

dangerous and faster and the weapons are better.

Who is the most fearsome house robot this time around?

She is nippy and has a fly wheel at the back,

she's probably got the most dangerous weapon in the arena.

Dead Metal is terrifying and has a front spinning blades,

which isn't actually that dangerous but makes a lot of sparks

and she has pincers, she grabs you with her pincers

and she pulls you forward and chops you in half.

Then Shunt has an axe that fires from one side to the other

That's it for now, I'll be back with more in half an hour.
