This is my sister Katie.
Get out Freddie.
This is Freddie.
When he’s not playing the violin – or annoying his sister - the 14-year-old is an award-winning inventor.
He’s created two solutions to help his 89-year-old great aunt Pat...
It'll stop when it recognises the fallen person.
... who's got dementia.
Freddie created a facial recognition door entry system for the elderly.
I'd noticed that random strangers would come up to the door, like cold callers,
and she'd be paying for stuff she didn't need.
So I developed it so that only known faces would be able to enter the housel
Door Pi uses a sensor to detect movement. Then it uses a camera to take a picture of your face.
"Please look directly into the camera."
Because it’s recognised my face it’s asking to scan my ID tag for 2 factor authentification.
"Welcome Freddie. I'm opening the door."
"The door is now open. Enter and remember to close the door behind you."
Freddie entered Door Pi into the Big Bang competition
and won junior engineer of the year.
He first became interested in engineering at primary school.
I joined a code club in my primary school in year four or five.
And I just learnt coding through there. And then I've loved coding ever since.
A year after making Door Pi, Freddie had another idea to help his Auntie Pat.
We'd realised that my Great Aunt Pat would fall, but would forget to press her button.
So she'd be found several hours later by her carers.
Fall Alert is a wearable sensor that automatically sends an alert if you fall.
It then despatches a robot to look for you.
Fall Alert can detect and avoid obstacles.
An alert is also sent to a relative's phone.
They can even control Fall Alert remotely using a video feed.
There - I've found Aunty Pat hidden behind the sofa.
Freddie roped in his family to help test the prototype.
The most challenging part of making Fall Alert was definitely getting the fall algorithm right.
Because there were so many different factors that I needed to include so that it didn't trigger any false positives.
Just testing, I'd edit the algorithms thoroughly and I'd get my Mum to repeatedly fall on the floor,
so that I got everything that happened during a fall, so that I could create the algorithm.
She was happy when it was over.
Freddie entered Fall Alert into the Big Bang competition,
and won for the second year running.
His dream is to see one of his projects go to market.
We’ve set Freddie up for a surprise chat with entrepreneur Ruth Amos, a former young inventor of the year herself.
Freddie, how are you doing? Good thanks.
I'm the inventor of Stair Steady, which was my GCSE project,
and I won the same award that you did Freddie, a long time ago.
And Stair Steady is a mobility product, to help people walk up and down their own stairs.
So what advice would you give me to help me bring my project to market.
I would just ask lots of questions.
I would try and meet people, pick their brains.
And decide what you want to do with it. Because for some people, I know lots of people
who've created projects and it's been a great way to showcase their skills, to go
on to University. For others, they want to get it to market.
So decide what you want to do with that product.
Thank you Freddie - it's been so lovely to finally meet you, even though it's virtually.
Thank you, bye.
Freddie has told his great-aunt Pat about his inventions
But I don’t think she’ll remember about them.
