we tried to build robots that learn a

little bit like humans do by trial and

error what we’ve done is trained an

algorithm to solve the Rubik’s Cube

one-handed with a robotic captain which

is actually pretty hard even for a human

to do we don’t tell it how the hand is

to move the the cube in order to get

there the particular friction that’s on

the fingers how easy it is to turn the

faces on the cube what the gravity what

the weight of the cube is all of these

things it needs to learn by itself

the interesting thing is that kind of

standard techniques in robotics haven’t

been able to scale to that complexity

that we see in a robotic hand humans

have evolved to be able to manipulate

and operate our hands so there’s a huge

amount of learning that’s happened

through evolution to get us to this

point as a as a species and the robot

has to learn all of this from scratch

instead of trying to write very

dedicated algorithms to operate such a

hand we took a different approach where

we create thousands of different

simulated environments and learn to do

the task in all of those and hopefully

the robotic hand will be able to do it

in the real world as well this means

like thousands of years of experience

that is your network has had in

simulation every time the argument good

at the task we make the task harder

that’s really crucial because you need

exposure to really complicate

environments in order to eventually be

robust to the real world you put a

rubber glove on their hand and can still

carry out the task

this ability to generalize to new

environments feels like a very poor

piece of intelligence it really changes

the way we think about training of

general purpose robots

moving from thinking too much about the

actual arguments and start thinking

about how do we create complex enough

worlds where they can learn at some

point then it would be more down to the

imagination

what robots could actually accomplish

they hope is to build robots that can do

many different tasks to increase the

standard of living and give everybody a

better life
