00:00:03.771 --> 00:00:06.271
DAISY: For the heavy lifting
involved in exploring the

00:00:06.273 --> 00:00:09.141
universe, NASA has the right
stuff...

00:00:09.143 --> 00:00:12.845
it's the TRIATHLETE Robot and
we've got it's moving story...

00:00:12.846 --> 00:00:15.081
next on Real World...

00:00:16.558 --> 00:00:19.458
? [music] ?

00:00:23.408 --> 00:00:26.258
DAISY: NASA recently spent the
better part of a month in the

00:00:26.260 --> 00:00:30.030
desolate plains of Northern
Arizona, testing systems that

00:00:30.031 --> 00:00:33.666
will one day be used to explore
other places in the universe.

00:00:33.668 --> 00:00:36.601
The event is known as Desert
RATS...

00:00:36.603 --> 00:00:39.405
that's Research and Technology
Studies.

00:00:39.406 --> 00:00:42.141
And one of the stars of this
show is a heavy lifting

00:00:42.143 --> 00:00:45.445
super robot with a very sporty
name.

00:00:45.446 --> 00:00:48.415
JULIE TOWNSEND: Well behind me,
here is the TRIATHLETE.

00:00:48.416 --> 00:00:51.550
It's the new generation of the
ATHLETE vehicle.

00:00:51.551 --> 00:00:54.420
DAISY: Julie Townsend is an
engineer working with robotics

00:00:54.421 --> 00:00:57.990
at NASA's Jet Propulsion Lab in
Pasadena, California.

00:00:57.991 --> 00:01:01.026
JULIE: ATHLETE is the
All-Terrain, Hex-Limbed, Extra-

00:01:01.028 --> 00:01:04.130
Terrestrial Explorer. And this
one is called the TRIATHLETE

00:01:04.131 --> 00:01:06.365
because it has a new feature.
It can actually split

00:01:06.366 --> 00:01:09.768
into two three-legged robots.
The reason that we split it

00:01:09.770 --> 00:01:11.938
into two three-legged robots is
because that's very

00:01:11.940 --> 00:01:14.673
convenient for moving cargo
around.

00:01:14.675 --> 00:01:17.410
DAISY: So the TRIATHLETE works
like a forklift on

00:01:17.411 --> 00:01:20.746
steroids picking up cargo on a
palette.

00:01:20.748 --> 00:01:22.948
JULIE: Each of those three
legged robots comes up

00:01:23.018 --> 00:01:25.133
and docks the side of that
palette and can carry

00:01:25.205 --> 00:01:27.331
it around. It's very easy for
them to set it

00:01:27.400 --> 00:01:29.665
down and drive away.

00:01:29.733 --> 00:01:32.458
DAISY: This makes it very easy
to offload cargo from a lander,

00:01:32.526 --> 00:01:36.661
and organize it at the landing
site. And it's versatile, too

00:01:36.663 --> 00:01:40.466
doing lots more than just heavy
lifting. TRIATHLETE can be

00:01:40.468 --> 00:01:44.070
fitted with special tools, to
accomplish all sorts of tasks.

00:01:45.033 --> 00:01:48.006
JULIE: The reason we call the
ATHLETE hex-limbed rather than

00:01:48.075 --> 00:01:51.076
hex-legged is because each leg
can also be used

00:01:51.078 --> 00:01:53.846
as a robotic arm. So what we're
going to be doing is

00:01:53.848 --> 00:01:56.683
we're going to drive up to that
cliff face behind us, and we're

00:01:56.685 --> 00:01:58.785
going to pick up one of the
arms, and we're going to put a

00:01:58.786 --> 00:02:00.920
gripper on the end of it. And
we're actually going to pull

00:02:00.921 --> 00:02:03.121
rocks off the cliff face with
the gripper as if we were doing

00:02:03.123 --> 00:02:05.858
a geologic survey of the cliff.

00:02:05.860 --> 00:02:08.260
DAISY: Geologists can learn a
lot about a planet

00:02:08.261 --> 00:02:10.396
by examining cliff faces.

00:02:10.398 --> 00:02:12.865
JULIE: They show the layers of
the rock in the order that they

00:02:12.866 --> 00:02:15.335
were laid down in history. So
they can get a lot of the

00:02:15.336 --> 00:02:19.471
history of a planet or a moon
from seeing the rocks in cliff

00:02:19.473 --> 00:02:23.008
faces like that. But normal
rovers can't reach the top of

00:02:23.010 --> 00:02:26.111
the cliff faces. So that's a
unique capability that ATHLETE

00:02:26.113 --> 00:02:29.048
has is that it has a really
long reach and so it can sample

00:02:29.050 --> 00:02:31.116
all the different layers of
that cliff

00:02:31.118 --> 00:02:33.586
all the way up to the top.

00:02:34.301 --> 00:02:36.726
DAISY: Another tool that got
put to the test in Arizona

00:02:36.795 --> 00:02:38.991
is a special attachment that
turns TRIATHLETE

00:02:38.993 --> 00:02:41.728
into a soil-moving machine.

00:02:41.730 --> 00:02:44.430
JULIE: We put this scoop on and
it can reach out and dig a

00:02:44.431 --> 00:02:48.668
trench in the surface and dump
that material elsewhere,

00:02:48.670 --> 00:02:51.270
just like you would do with a
backhoe. It's one of the

00:02:51.271 --> 00:02:55.241
things that makes the ATHLETE
such a utility vehicle.

00:02:55.243 --> 00:02:58.578
DAISY: When we last checked in
on this project, we talked

00:02:58.580 --> 00:03:01.280
about the mathematical concept
of scaling.

00:03:01.281 --> 00:03:04.283
The precursor to this robot,
known as ATHLETE

00:03:04.285 --> 00:03:08.500
was a 1/3 scale model. This
version is Ĺ scale.

00:03:08.501 --> 00:03:11.023
The one that would be used for
exploration in other places in

00:03:11.025 --> 00:03:14.060
the universe will stand 8
meters tall.

00:03:14.061 --> 00:03:16.730
JULIE: So it would be twice as
big in every dimension.

00:03:16.731 --> 00:03:19.131
But this one really gives you
the sense of exactly how

00:03:19.133 --> 00:03:21.300
huge that would be.

00:03:21.301 --> 00:03:23.436
DAISY: So you can see the
progression, from the first

00:03:23.438 --> 00:03:27.940
ATHLETE, built in 2005 to this
new TRIATHLETE, which is larger

00:03:27.941 --> 00:03:30.243
and can split into to separate
robots.

00:03:30.245 --> 00:03:33.880
Other additions to this latest
version include stronger joints

00:03:33.948 --> 00:03:36.050
and a new power system.

00:03:37.818 --> 00:03:41.256
The TRIATHLETE was developed at
NASA's Jet Propulsion Lab in

00:03:41.258 --> 00:03:44.190
Pasadena California, where they
know a thing or two

00:03:44.191 --> 00:03:46.693
about operating robots and
rovers.

00:03:46.695 --> 00:03:49.695
JULIE: We have a lot of
experience with remotely

00:03:49.696 --> 00:03:52.398
operating robots on the surface
of other planets. We operate

00:03:52.400 --> 00:03:55.101
the Mars Exploration rovers,
Spirit and Opportunity.

00:03:55.103 --> 00:03:57.736
We're developing new rovers to
go to Mars right now.

00:03:57.738 --> 00:04:00.706
So we operate ATHLETE, very
similarly to how we operate the

00:04:00.708 --> 00:04:03.476
Mars Exploration Rovers.
Generally when I'm operating

00:04:03.478 --> 00:04:06.411
the robot, I sit behind a
workstation where I list out

00:04:06.413 --> 00:04:08.515
all the different thing I want
the robot to do, then I send

00:04:08.516 --> 00:04:11.150
those to the robot to be
performed.

00:04:11.151 --> 00:04:14.286
DAISY: Julie organizes the days
commands on a block schedule

00:04:14.288 --> 00:04:17.323
similar to the one you might
use to see your class schedule,

00:04:17.325 --> 00:04:19.991
or to look up TV programs for
the day.

00:04:20.968 --> 00:04:24.663
In Arizona, at Desert RATS,
TRIATHLETE performed many of

00:04:24.731 --> 00:04:27.466
the tasks it will do on other
planets one day.

00:04:27.468 --> 00:04:31.303
It moved cargo, did geological
surveys and even performed a

00:04:31.305 --> 00:04:34.473
docking with the Lunar Electric
Rover.

00:04:35.043 --> 00:04:37.776

RATS, Robotics
