00:00:00.260 --> 00:00:02.600
When you have a long history of bad knees like me,
2
00:00:02.600 --> 00:00:04.520
jumping off a ledge with a 50-pound weight
3
00:00:04.520 --> 00:00:06.210
on your back is a surefire recipe
4
00:00:06.210 --> 00:00:08.050
for months of PT and crutches.
5
00:00:08.050 --> 00:00:09.920
But when you're wearing a military-grade
6
00:00:09.920 --> 00:00:13.023
robotic knee brace, theoretically, you should be okay.
7
00:00:15.421 --> 00:00:17.520
[exhales] Moment of truth.
8
00:00:17.520 --> 00:00:20.770
I'm like very nervous, [chuckles] I know.

I'm Brent Rose and I'm about to pay for my

orthopedist's Hawaiian vacation.

two,
13
00:00:26.540 --> 00:00:27.373
one.
14
00:00:29.060 --> 00:00:31.150
Oh yeah, baby!
15
00:00:31.150 --> 00:00:31.983
Ugh,
16
00:00:31.983 --> 00:00:34.310
all day!
17
00:00:34.310 --> 00:00:35.270
Sweet!
18
00:00:35.270 --> 00:00:37.360
You're not going anywhere Dr. Shapiro.
19
00:00:37.360 --> 00:00:38.760
Let's jump off a roof.
20
00:00:38.760 --> 00:00:42.730
[upbeat techno music]
21
00:00:42.730 --> 00:00:44.970
So you've heard about augmented reality, right?
22
00:00:44.970 --> 00:00:47.470
Well, how about augmented mobility?
23
00:00:47.470 --> 00:00:50.180
Robotic exoskeletons have captivated us for years.
24
00:00:50.180 --> 00:00:52.040
They're major tropes in Sci-Fi movies
25
00:00:52.040 --> 00:00:54.350
like "Aliens", "Elysium", and "Avatar".
26
00:00:54.350 --> 00:00:56.600
But in real life, engineers have been working on them
27
00:00:56.600 --> 00:00:58.210
since the early 1900s,
28
00:00:58.210 --> 00:01:00.534
generally with terrible clunky results.
29
00:01:00.534 --> 00:01:02.720
Here, we see the electrically powered machine
30
00:01:02.720 --> 00:01:04.680
built into the form of a human skeleton.
31
00:01:04.680 --> 00:01:06.190
While there've been some real breakthroughs
32
00:01:06.190 --> 00:01:08.060
in recent years, most of them are still bulky,
33
00:01:08.060 --> 00:01:10.700
prohibitively power hungry, as well as expensive.
34
00:01:10.700 --> 00:01:12.130
That's why a San Francisco company
35
00:01:12.130 --> 00:01:14.199
called Roam Robotics caught my eye.
36
00:01:14.199 --> 00:01:17.870
[rhythmic bass beats]
37
00:01:17.870 --> 00:01:20.110
Roam claims to have solved a lot of these problems,
38
00:01:20.110 --> 00:01:21.930
making a robotic knee brace that promises
39
00:01:21.930 --> 00:01:23.460
to double your strength and endurance
40
00:01:23.460 --> 00:01:25.590
in reduced-experience G-forces by half,
41
00:01:25.590 --> 00:01:27.580
all while doing it in a package that's lightweight,
42
00:01:27.580 --> 00:01:29.970
lasts up to eight hours, and is relatively affordable.
43
00:01:29.970 --> 00:01:31.790
If you think that sounds too good to be true,
44
00:01:31.790 --> 00:01:32.690
you're not alone.
45
00:01:32.690 --> 00:01:34.100
So today we're going to stress test
46
00:01:34.100 --> 00:01:35.341
the hell out of this thing.
47
00:01:35.341 --> 00:01:37.500
[treadmill whirring]
48
00:01:37.500 --> 00:01:38.790
Oh yeah.
How's that feel?
49
00:01:38.790 --> 00:01:40.180
Definitely feeling it now.
50
00:01:40.180 --> 00:01:42.070
And considering I just re-injured my knee,
51
00:01:42.070 --> 00:01:43.970
we're gonna be stress testing me, too.
52
00:01:44.960 --> 00:01:46.510
Ooh, slipped.
53
00:01:46.510 --> 00:01:47.343
I'm fine.
54
00:01:48.210 --> 00:01:49.140
I'm Tim Swift.
55
00:01:49.140 --> 00:01:51.210
I'm the founder and CEO of Roam Robotics.
56
00:01:51.210 --> 00:01:52.870 line:15%
So we have one line of product,
57
00:01:52.870 --> 00:01:55.120 line:15%
which is a performance product, which is Forge.
58
00:01:55.120 --> 00:01:58.120
And that is really designed for military first-responders.
59
00:01:58.120 --> 00:02:00.250
What are some of the specific applications
60
00:02:00.250 --> 00:02:02.770
that you've seen it used for first responders and military?
61
00:02:02.770 --> 00:02:03.603
Firefighters.
62
00:02:03.603 --> 00:02:06.010
Firefighters walk in with significant amounts of gear
63
00:02:06.010 --> 00:02:08.640
and it's unacceptable for them to find themselves impeded.
64
00:02:08.640 --> 00:02:10.520
If there's fires that aren't on ground floors
65
00:02:10.520 --> 00:02:11.860
or multi-story buildings,
66
00:02:11.860 --> 00:02:13.950
they're not taking elevators up to those needs,
67
00:02:13.950 --> 00:02:16.800
they're carrying their gear and typically backup gear.
68
00:02:16.800 --> 00:02:19.960
Some of our customers are sending an extra guy
69
00:02:19.960 --> 00:02:21.630
for the sole goal of carrying all the gear
70
00:02:21.630 --> 00:02:24.070
'cause they know by the time they make it to the 20th floor,
71
00:02:24.070 --> 00:02:25.100
that guy is smoked.
72
00:02:25.100 --> 00:02:27.530
His only job is to carry the gear and get out.
73
00:02:27.530 --> 00:02:30.470
We go out with maritime users in small boats,
74
00:02:30.470 --> 00:02:31.860
and these guys are taking, you know,
75
00:02:31.860 --> 00:02:34.520
50-mile-an-hour speeds over 10-foot sea states.
76
00:02:34.520 --> 00:02:36.860
And they're just getting beat by the G-forces.
77
00:02:36.860 --> 00:02:38.370 line:15%
And we can put systems on users
78
00:02:38.370 --> 00:02:40.900 line:15%
and we get a 50% reduction in G-forces immediately,
79
00:02:40.900 --> 00:02:41.950 line:15%
no training involved.
80
00:02:42.860 --> 00:02:45.430 line:15%
I'm excited to beat myself up in this thing.
81
00:02:45.430 --> 00:02:46.880
That's great.
82
00:02:46.880 --> 00:02:49.200
What makes Roam's military leg brace unique
83
00:02:49.200 --> 00:02:51.010
is that it uses pneumatic actuators
84
00:02:51.010 --> 00:02:52.890
instead of heavy motors and servos.
85
00:02:52.890 --> 00:02:54.410
That means it's using compressed air
86
00:02:54.410 --> 00:02:56.050
to augment your knee movements.
87
00:02:56.050 --> 00:02:59.460
And in theory, give you up to two times your own strength.
88
00:02:59.460 --> 00:03:02.160 line:15%
Specifically, this is designed for military members
89
00:03:02.160 --> 00:03:03.010 line:15%
or first responders.
90
00:03:03.010 --> 00:03:06.010 line:15%
So the size is probably pretty close to where you're at.
91
00:03:06.010 --> 00:03:08.700
Yeah, tech journalist/military first responder.
92
00:03:08.700 --> 00:03:10.000
It's perfect, right?
It's about the same.
93
00:03:10.000 --> 00:03:12.150
You have a brace on each leg
94
00:03:12.150 --> 00:03:13.990
and then you have a power pack that powers both of them.
95
00:03:13.990 --> 00:03:16.560
So that comprises kind of the two main parts of the system.
96
00:03:16.560 --> 00:03:18.520 line:15%
This contains the compressor,
97
00:03:18.520 --> 00:03:20.280 line:15%
some of the brains and that work in conjunction
98
00:03:20.280 --> 00:03:22.030 line:15%
with the sensors on the units themselves,
99
00:03:22.030 --> 00:03:24.830
all controlled by the remote that's on your left shoulder.
100
00:03:24.830 --> 00:03:25.890
If you wanna go ahead and press and hold,
101
00:03:25.890 --> 00:03:26.860
that'll turn it on.
102
00:03:26.860 --> 00:03:28.310
All right, moment of truth.
103
00:03:29.151 --> 00:03:30.660
[compressor whirring]
104
00:03:30.660 --> 00:03:32.840
Good morning.
[compressor whirring]
105
00:03:32.840 --> 00:03:34.960
Oh yeah.
[compressor whirring]
106
00:03:34.960 --> 00:03:37.210
Yeah, it's very springy.
107
00:03:37.210 --> 00:03:40.010
I couldn't help but notice that anytime I move
108
00:03:40.010 --> 00:03:42.430
there's a bit of a noise coming out of it.
109
00:03:42.430 --> 00:03:43.740
What is that we're hearing?
110
00:03:43.740 --> 00:03:45.180
Yeah, so what you're hearing right now
111
00:03:45.180 --> 00:03:47.560
is the compressor itself charging up air
112
00:03:47.560 --> 00:03:50.320
to supply to each of the braces themselves.
113
00:03:50.320 --> 00:03:53.020
Part of what you're also hearing is when you move,
114
00:03:53.020 --> 00:03:54.740
there's the filling portion
115
00:03:54.740 --> 00:03:55.960
for the actuator.
That's that rumble.
116
00:03:55.960 --> 00:03:58.490
And then as you come back up, you'll hear venting.
117
00:03:58.490 --> 00:04:00.920
So some of that is both the brace sound
118
00:04:00.920 --> 00:04:02.480
and the power pack sound.
119
00:04:02.480 --> 00:04:04.500
It's something we're working towards reducing,
120
00:04:04.500 --> 00:04:05.640
but that's what you're hearing.
121
00:04:05.640 --> 00:04:07.040
And that's what some of the vibrations are
122
00:04:07.040 --> 00:04:07.874
that you're feeling.
123
00:04:07.874 --> 00:04:10.290
[weights clanking]
124
00:04:10.290 --> 00:04:11.890
Okay, so we're gonna start with a controlled test
125
00:04:11.890 --> 00:04:13.440
and to do that we're gonna do some squatting,
126
00:04:13.440 --> 00:04:15.260
which I haven't done in like 20 years.
127
00:04:15.260 --> 00:04:17.080
Normally you want to do this to failure.
128
00:04:17.080 --> 00:04:19.460
Failure for me, since I have a freshly tweaked knee,
129
00:04:19.460 --> 00:04:21.430
is gonna be any inkling of pain
130
00:04:21.430 --> 00:04:24.610
or just me passing out with a dumbbell on my head.
131
00:04:24.610 --> 00:04:26.610
All right, so this is 185.
132
00:04:26.610 --> 00:04:27.810
Let's see how this goes.
133
00:04:30.425 --> 00:04:33.842
[Brent exhaling sharply]
134
00:04:40.820 --> 00:04:42.270
How red is my face right now?
135
00:04:43.556 --> 00:04:45.900
Whoa, yep, we'll call it good.
136
00:04:45.900 --> 00:04:46.893
Four is good.
137
00:04:48.424 --> 00:04:49.520
[Brent exhales sharply]
138
00:04:49.520 --> 00:04:50.810
Now I've got the Forge on,
139
00:04:50.810 --> 00:04:52.550
we're gonna turn it up to max support mode.
140
00:04:52.550 --> 00:04:53.661
Let's see what we can do here.
141
00:04:53.661 --> 00:04:57.610
[compressor whirring]
142
00:04:57.610 --> 00:04:59.000
All right.
143
00:04:59.000 --> 00:05:00.610
It's okay to be scared.
144
00:05:00.610 --> 00:05:01.463
Here we go.
145
00:05:03.492 --> 00:05:06.659
[compressor whirring]
146
00:05:07.730 --> 00:05:08.930
Huh.
147
00:05:08.930 --> 00:05:11.440
Definitely feeling a lot more
148
00:05:12.390 --> 00:05:13.223
push
149
00:05:14.910 --> 00:05:16.443
on my backs of my thighs.
150
00:05:17.530 --> 00:05:20.180
I also don't feel like I'm about to have an embolism,
151
00:05:20.180 --> 00:05:21.253
so that's good.
152
00:05:22.660 --> 00:05:24.880
I can still have a conversation,
153
00:05:24.880 --> 00:05:25.830
so that's good too.
154
00:05:26.830 --> 00:05:27.910
Oh yeah.
155
00:05:27.910 --> 00:05:30.250
Am definitely feeling it, though.
156
00:05:30.250 --> 00:05:31.740
Let's call that failure.
157
00:05:31.740 --> 00:05:32.573
Eight!
158
00:05:36.190 --> 00:05:38.270
I'm pretty happy with that.
159
00:05:38.270 --> 00:05:40.270
I'm gonna go pass out for a second here.
160
00:05:43.570 --> 00:05:44.580
It's fine.
161
00:05:44.580 --> 00:05:45.480
Everything's fine.
162
00:05:46.950 --> 00:05:49.160
So the Forge isn't built to assist with your running,
163
00:05:49.160 --> 00:05:50.430
but it is built in such a way
164
00:05:50.430 --> 00:05:51.950
that it shouldn't impede your running.
165
00:05:51.950 --> 00:05:54.060
So when it's powered off, it's not getting in my way,
166
00:05:54.060 --> 00:05:55.610
but it's not assisting either.
167
00:05:55.610 --> 00:05:58.750
It's not designed to assist, but let's see what happens.
168
00:05:58.750 --> 00:06:01.133
[compressor whirring]
That's never gonna get old.
169
00:06:02.758 --> 00:06:04.640
[Brent chuckling]
170
00:06:04.640 --> 00:06:06.520
It's really huffing and puffing.
171
00:06:06.520 --> 00:06:08.120
Let's go up to six.
172
00:06:08.120 --> 00:06:09.340
All right.
173
00:06:09.340 --> 00:06:12.010
So I can feel there's some resistance
174
00:06:12.010 --> 00:06:14.460
and I can't tell if it's making it harder or easier.
175
00:06:14.460 --> 00:06:15.560
Again, I'm still feeling the weight.
176
00:06:15.560 --> 00:06:17.350
I'm feeling the pressure in the back of my thighs
177
00:06:17.350 --> 00:06:18.820
and around my ankles,
178
00:06:18.820 --> 00:06:21.573
but my knees feel totally fine right now.
179
00:06:22.500 --> 00:06:24.080
So that's good.
180
00:06:24.080 --> 00:06:28.093
It's not helping, but if I turn it off again.
181
00:06:28.960 --> 00:06:30.120
Oh yeah.
182
00:06:30.120 --> 00:06:32.750
Oh yeah, let's go without, definitely better without.
183
00:06:32.750 --> 00:06:35.380
Yeah, so I tried at level one and at level three,
184
00:06:35.380 --> 00:06:36.950
it was definitely impeding a little bit.
185
00:06:36.950 --> 00:06:39.380
It's just kind of resisting against your knees
186
00:06:39.380 --> 00:06:41.090
in a way that doesn't help you.
187
00:06:41.090 --> 00:06:43.320
It took some of the impact off my knees, which was nice,
188
00:06:43.320 --> 00:06:44.790
but I was kind of having to fight against it.
189
00:06:44.790 --> 00:06:48.225
So if you gotta run with this thing, turn it off.
190
00:06:48.225 --> 00:06:50.580
[Brent pants]
191
00:06:50.580 --> 00:06:53.910
This is the impact test, which I'm rather nervous about.
192
00:06:53.910 --> 00:06:56.010
We don't have a boat, but this is gonna simulate
193
00:06:56.010 --> 00:06:57.560
that sort of high-seas situation
194
00:06:57.560 --> 00:06:59.900
and the impacts that it'd be taking on my legs.
195
00:06:59.900 --> 00:07:01.120
We're on the high box.
196
00:07:01.120 --> 00:07:02.770
This one's a little bit scary for me.
197
00:07:02.770 --> 00:07:03.780
Three,
198
00:07:03.780 --> 00:07:04.613
two,
199
00:07:04.613 --> 00:07:05.446
one.
200
00:07:06.402 --> 00:07:09.223
[compressor whirring]
Feel it on my feet.
201
00:07:10.880 --> 00:07:11.713
Excuse me.
202
00:07:12.930 --> 00:07:13.763
Burrito.
203
00:07:14.953 --> 00:07:16.620
[crew laughing]
204
00:07:16.620 --> 00:07:18.200
Actually wanna try do that one again
205
00:07:18.200 --> 00:07:19.500
with a Spider-Man landing.
206
00:07:22.340 --> 00:07:24.033
Oh, hell yeah.
207
00:07:24.033 --> 00:07:26.830
[groovy music]
208
00:07:26.830 --> 00:07:28.360
It's worth noting that while we're just
209
00:07:28.360 --> 00:07:29.550
testing the Forge today,
210
00:07:29.550 --> 00:07:31.760
which is designed for these types of high impacts,
211
00:07:31.760 --> 00:07:35.000
Roam has two other models, the Ascend and the Elevate.
212
00:07:35.000 --> 00:07:37.510
The Ascend is designed mostly for people with knee issues,
213
00:07:37.510 --> 00:07:39.070
and it helps them with things like standing
214
00:07:39.070 --> 00:07:41.270
and sitting and going up and down stairs.
215
00:07:41.270 --> 00:07:42.750
The Elevate is made for skiers
216
00:07:42.750 --> 00:07:44.360
whose knees aren't what they used to be.
217
00:07:44.360 --> 00:07:46.490
I actually got to test it in Big Sky, Montana
218
00:07:46.490 --> 00:07:47.610
a couple winters ago,
219
00:07:47.610 --> 00:07:49.610
and it did in fact help me power through turns
220
00:07:49.610 --> 00:07:51.330
with less strain on my knees.
221
00:07:51.330 --> 00:07:52.930
Though, the sounds of the air compressor
222
00:07:52.930 --> 00:07:55.845
in an otherwise tranquil place was pretty hard to ignore.
223
00:07:55.845 --> 00:07:57.890
[compressor whirring]
224
00:07:57.890 --> 00:07:59.580
So the Forge did pretty well in the lab
225
00:07:59.580 --> 00:08:00.770
in some controlled testing.
226
00:08:00.770 --> 00:08:02.900
So let's try a little less controlled testing.
227
00:08:02.900 --> 00:08:04.700
They told me specifically that it will not help me
228
00:08:04.700 --> 00:08:05.950
dunk a basketball.
229
00:08:05.950 --> 00:08:07.400
We're gonna prove them wrong.
230
00:08:09.610 --> 00:08:10.443
Perfect.
231
00:08:10.443 --> 00:08:13.374
[groovy bass music]
232
00:08:18.430 --> 00:08:20.430
All right, I'm all Forged up now.
233
00:08:20.430 --> 00:08:23.604
Let's see if this improves my vertical at all.
234
00:08:23.604 --> 00:08:27.070
[Brent exhales sharply]
235
00:08:27.070 --> 00:08:27.982
Ah!
236
00:08:27.982 --> 00:08:29.370
Mmmmmmm,
237
00:08:29.370 --> 00:08:30.250
no.
238
00:08:30.250 --> 00:08:31.163
Come on baby!
239
00:08:32.050 --> 00:08:32.930
Ah!
240
00:08:32.930 --> 00:08:33.960
I cannot fly.
241
00:08:33.960 --> 00:08:35.780
I was wrong to believe that I could fly
242
00:08:35.780 --> 00:08:37.620
and I feel stupid now.
243
00:08:37.620 --> 00:08:40.280
Okay, fine, so it was not designed for dunking.
244
00:08:40.280 --> 00:08:42.700
Let's try a few things that it was designed for.
245
00:08:42.700 --> 00:08:45.290
So a more realistic scenario might be a firefighter
246
00:08:45.290 --> 00:08:47.000
having to carry a person outta harm's way.
247
00:08:47.000 --> 00:08:49.180
And that could be up many, many flights of stairs.
248
00:08:49.180 --> 00:08:51.030
So to simulate a dead body,
249
00:08:51.030 --> 00:08:52.570
we're gonna use our director Morgan, here.
250
00:08:52.570 --> 00:08:54.480
Feeling dead body-ish?
Let's do it.
251
00:08:54.480 --> 00:08:55.830
All right here we go.
252
00:08:55.830 --> 00:08:57.730 line:15%
Oh yeah, how's that feel?
Excellent.
253
00:08:57.730 --> 00:08:59.770 line:15%
And we're going up.
254
00:08:59.770 --> 00:09:00.947
Oh yeah.
255
00:09:00.947 --> 00:09:02.860
[compressor whirring]
256
00:09:02.860 --> 00:09:04.990
You can hear the pistons working,
257
00:09:04.990 --> 00:09:07.780
but I can still kinda carry on a normal conversation,
258
00:09:07.780 --> 00:09:10.833
which I was really, really not expecting.
259
00:09:12.520 --> 00:09:13.860
Hi, pup.
260
00:09:13.860 --> 00:09:15.250
That was actually pretty good.
261
00:09:15.250 --> 00:09:17.423 line:15%
How you doing dead body?
This is my stop.
262
00:09:17.423 --> 00:09:19.640 line:15%
Perfect.
Thank you.
263
00:09:19.640 --> 00:09:21.060 line:15%
Thank you.
All right.
264
00:09:23.039 --> 00:09:27.540
[groaning] Not exactly the stealthiest contraption,
265
00:09:27.540 --> 00:09:32.400
but if I have to make a hard landing, I am really loving it.
266
00:09:32.400 --> 00:09:35.060
And if I need to sneak around, just turn it off,
267
00:09:35.060 --> 00:09:36.183
and get real sneaky.
268
00:09:39.440 --> 00:09:41.070
All right, let's talk highs and lows.
269
00:09:41.070 --> 00:09:42.690
Highs, I was able to squat
270
00:09:42.690 --> 00:09:44.520
more than my body weight eight times.
271
00:09:44.520 --> 00:09:46.490
That is something I never would've been able to do
272
00:09:46.490 --> 00:09:47.870
under normal circumstances.
273
00:09:47.870 --> 00:09:50.710
Two, I was able to jump off a high platform with weight
274
00:09:50.710 --> 00:09:52.470
and land like fricking Spider-Man.
275
00:09:52.470 --> 00:09:56.020
I will do that all day long 'cause that was stupid fun.
276
00:09:56.020 --> 00:09:58.940
Three, I've been on my feet all day long,
277
00:09:58.940 --> 00:10:01.270
carrying weight, going up and down things,
278
00:10:01.270 --> 00:10:03.930
carrying Morgan and my legs feel good.
279
00:10:03.930 --> 00:10:05.920
My knees aren't really shot.
280
00:10:05.920 --> 00:10:08.460
I could still do stuff.
281
00:10:08.460 --> 00:10:10.370
And that's kind of a miracle in itself,
282
00:10:10.370 --> 00:10:12.800
especially considering I just tweaked my knee recently.
283
00:10:12.800 --> 00:10:14.820
Lows, when I didn't have the brace on
284
00:10:14.820 --> 00:10:16.630
I tried to squat more than my body weight
285
00:10:16.630 --> 00:10:17.600
without warming up
286
00:10:17.600 --> 00:10:19.850
and I thought it was going to face plant and die.
287
00:10:19.850 --> 00:10:20.683
Bad call.
288
00:10:20.683 --> 00:10:23.110
Two, I may have sprained this finger
289
00:10:23.110 --> 00:10:25.070
jumping out of a tree and landing awkwardly,
290
00:10:25.070 --> 00:10:28.190
which was definitely my fault, but what can you do?
291
00:10:28.190 --> 00:10:30.450
And three, this brace did not let me yam it
292
00:10:30.450 --> 00:10:32.180
like a professional basketball player.
293
00:10:32.180 --> 00:10:33.740
Truly a tragedy.
294
00:10:33.740 --> 00:10:35.380
But that's actually something
295
00:10:35.380 --> 00:10:37.280
that it could be programmed to do in the future,
296
00:10:37.280 --> 00:10:39.270
which I think is really cool.
297
00:10:39.270 --> 00:10:40.560
The other thing I couldn't ignore
298
00:10:40.560 --> 00:10:42.280
about the Forge is the noise.
299
00:10:42.280 --> 00:10:44.480
Right now, it sits at about 65 decibels,
300
00:10:44.480 --> 00:10:47.087
which is rather prominent indoors.

He he he he!
302
00:10:48.740 --> 00:10:51.150
Definitely not ready for the public library.
303
00:10:51.150 --> 00:10:52.420
Once they sort that out though,
304
00:10:52.420 --> 00:10:54.450
it'll be interesting to see how widespread
305
00:10:54.450 --> 00:10:55.900
this type of tech becomes,
306
00:10:55.900 --> 00:10:57.970
not just from Roam but from other innovators
307
00:10:57.970 --> 00:11:00.270
in the personal mobility space.
308
00:11:00.270 --> 00:11:01.490
With all that being said,
309
00:11:01.490 --> 00:11:03.726
we've got one more test left to do.
310
00:11:03.726 --> 00:11:06.893
[groovy techno music]
311
00:11:10.812 --> 00:11:13.867
[compressor whirring]
312
00:11:13.867 --> 00:11:17.898
Yes.
[Brent laughing]
313
00:11:17.898 --> 00:11:18.731
Beautiful.
314
00:11:20.810 --> 00:11:23.440
It is important to keep it contained around your thigh,
315
00:11:23.440 --> 00:11:25.920
but we're not looking to cut off circulation or to keep it-
316
00:11:25.920 --> 00:11:28.353
Nobody can contain these thighs, but go on.
