Small robots, big personalities
Just say “Hey Buzz”
He listens, thinks and answers in a voice of his own.
“Look at the door”
Armzz turns its head to the spot you name.
“Where’s the remote?”
Buzz checks the cameras and remembers where things were last seen.
Knows your voice
He learns your voice when you ask, and doesn’t answer the TV.
Keeps a diary
Ask “What have you been up to?” and get a real answer.
Thinks out loud
At home, their thoughts and decisions play live on a little wall tablet.
Say “Hey Buzz”. Five things happen.
Ears
hears his name
Words
turns speech into text
Brain
writes his answer
Voice
says it out loud
Mouth
moves along
All on computers in the house. No cloud.
Armzz sees the room in laser light.
A spinning laser measures everything around the cart, ten times a second, out to 12 metres. Slice by slice, it becomes a map.
A simulated scan of a made-up room.
They keep hours, like good housemates.
Right now at home: …
Waking8–10 am
Lively10 am–6 pm
Calm6–9 pm
Sleepy9–10 pm
Asleep10 pm–8 am
From ten at night to eight in the morning they’re asleep, and Buzz keeps his thoughts to himself.
Good housemates
Asleep by ten
Asks before learning a face or a voice
Heaters off, never on
A big red STOP knob
The story so far
First words over Bluetooth
Armzz rolls
A life of their own
A new brain
Thoughts, feelings and curiosity
“Look at the door”
A desk of their own
