- Huh.
[upbeat music]
- There's a lot of people
I think who are scared
robots are going
to take their jobs.
What do you think? Is
that possible I guess?
- Ya it's definitely possible,
and I think there are
certain jobs that are going
to be taken by robots,
but hopefully those
jobs will fall into the
3 D's as we say, which would
be dull, dirty and dangerous.
- Doing this corn hole move,
- Mhmm
- Would be pretty simple
for a robot, 'cause
all you're doing is that.
- Ya,
- that's not very hard.
It's a bunch of geometry that
we all learned in school,
but it just, it's a
lot of that geometry
and so it takes a long
time. Try it again.
- Okay, ahh.
- That's the tough part, can you
throw it without hitting my arm?
- Uh barely [laughs].
But that's the concern
[talking over one another]
- Yes, that's the
key technology,
it's the ability to motion
plan, such that you're not
going to hit objects
that are in your way.
You know moving, and so as
our camera is taking pictures
of what's in front of the robot,
we can adapt to each frame
of that, you know 30,
60, 90 frames per second.
Ya, good toss. You've
been practicing.
So what we ended up doing is
we built our own hardware.
It's a computer but it does
nothing but motion planning.
By devoting all
of it's resources
to this one really
important task,
we can do it very efficiently.
So instead of it
taking multiple seconds
we can motion plan
in a millisecond.
Going back to the object
in front of the robot,
there are many,
many possible ways
for the robot to do
that, particularly
all of those joints.
We basically start
off with like,
let's say a very large number,
like a million
different small motions
that the robot can take,
and then from among those,
we chose to use only
those that won't collide
with something currently
in front of us.
- This is not a robotic arm,
this is not a robotic arm,
this is not a robotic arm.
- And we then stitch
together those little motions
to ones that don't collide,
to get from where we are
to where we want to be.
[thumping]
And what's nice is because
we can do this so quickly,
if the obstacles move,
I can do it again,
you know every millisecond,
so that even if
obstacles move, I just keep
re-planning on the fly.
- Should I be worried
that robots could be
taking over my corn hole
playing at some point?
- Well there is that risk.
