  • 00:00:01
    My name is Josh.
  • 00:00:02
    I've been at Boston Dynamics about four years now.
  • 00:00:05
    I'm a mechanical engineer on the Atlas team.
  • 00:00:07
    I think what first got me interested in high school,
  • 00:00:10
    I'd build a drone, a little quadcopter,
  • 00:00:12
    and it was it was absolutely terrible.
  • 00:00:14
    I could barely fly, but we did everything.
  • 00:00:17
    We did all the software, the electronics, and,
  • 00:00:20
    just going through the process of seeing how we're tuning
  • 00:00:23
    variables and it's responding to to inputs and trying to
  • 00:00:25
    stabilize was truly empowering.
  • 00:00:28
    And I think from there, I just felt, you know,
  • 00:00:30
    a desire to do more.
  • 00:00:31
    And in college, I kept on learning and building more
  • 00:00:33
    robots, did all the projects I could,
  • 00:00:35
    and eventually that led to working here.
  • 00:00:44
    As a mechanical engineer,
  • 00:00:45
    we design all the physical parts on the robot,
  • 00:00:47
    the arms and the legs, structures,
  • 00:00:49
    the motors and actuation, batteries,
  • 00:00:51
    anything on the robot that's physical and you can see there,
  • 00:00:54
    that's where we specialize.
  • 00:00:55
    We also do a lot of analysis and math to make sure that the
  • 00:00:58
    robot will work, that the joints are strong enough,
  • 00:01:00
    that if it face plants while doing a back flip,
  • 00:01:02
    things aren't gonna break and fall apart.
  • 00:01:04
    You know, know, it kinda goes through phases.
  • 00:01:05
    Some weeks, we're doing a lot of testing,
  • 00:01:07
    and we're breaking robots intentionally or or unintentionally.
  • 00:01:11
    Testing mechanisms, if they perform the way we expect to.
  • 00:01:13
    Other weeks are really design heavy.
  • 00:01:15
    And like everyone here,
  • 00:01:16
    we coordinate a lot with other teams and disciplines,
  • 00:01:18
    electrical engineers, software engineers,
  • 00:01:21
    to make sure that the robot will will work well.
  • 00:01:24
    So how do you build a robot?
  • 00:01:27
    So, yeah, for, the robots here in Boston Dynamics,
  • 00:01:30
    we really have to approach it from a systems level.
  • 00:01:33
    You can't sort of design each part individually in a bubble.
  • 00:01:36
    It'll never work that way.
  • 00:01:37
    You can think of it sort of as a a picture coming into focus
  • 00:01:41
    where there's a lot of blurred lines and and things aren't
  • 00:01:45
    really don't have much definition,
  • 00:01:46
    but we're trying to think about everything holistically.
  • 00:01:48
    And then throughout stages,
  • 00:01:50
    we're detailing out parts kind of in parallel at the same time.
  • 00:01:53
    So we take all these people, you know,
  • 00:01:55
    and as we're building the robot,
  • 00:01:56
    everyone's voicing concerns, contributing,
  • 00:01:59
    and then kinda through that large team effort,
  • 00:02:00
    you end up with a robot.
  • 00:02:02
    You're never the smartest person in the room and that's
  • 00:02:05
    the best place to be.
  • 00:02:07
    There's always so much to learn.
  • 00:02:09
    What does Atlas do? That question gets asked a lot.
  • 00:02:13
    So Atlas is our R&D robot, our research and development robot.
  • 00:02:17
    And you can think of it sort of as a technology demonstrator.
  • 00:02:21
    So we're really trying to push the limits of hardware and
  • 00:02:24
    software and controls with Atlas,
  • 00:02:26
    thinking about years and years into the into the future I mean,
  • 00:02:29
    how we can learn from that technology and spread it to all of our robots.
  • 00:02:33
    How fast can Atlas go?
  • 00:02:36
    So the fastest we've gotten it to go in lab is about two and a
  • 00:02:39
    half meters per second.
  • 00:02:41
    It's about five and a half miles per hour.
  • 00:02:43
    But there's sort of this running joke around here how we
  • 00:02:46
    keep on thinking we've capped out the robot,
  • 00:02:48
    and then the software team develops some new behavior that
  • 00:02:52
    is more athletic and coordinated than anything we've done before.
  • 00:02:56
    So we think there's quite a long ways to go before we've
  • 00:02:58
    capped out the hardware.
  • 00:03:00
    What was the first prototype of Atlas?
  • 00:03:03
    So the first was way before my time.
  • 00:03:05
    It was called Petman Proto.
  • 00:03:06
    It was actually our robot, BigDog,
  • 00:03:06
    which you may have seen.
  • 00:03:07
    It's one of the classic ones where we kick it and it stabilizes.
  • 00:03:09
    It was that robot.
  • 00:03:11
    We just took
  • 00:03:13
    took two legs from it and stood it on its hind legs,
  • 00:03:15
    and then we attached two arms to it.
  • 00:03:18
    And that was the predecessor to our first full humanoid robot called Petman,
  • 00:03:22
    and then that led to over a decade of development and
  • 00:03:26
    iteration to the robot you see nowadays,
  • 00:03:28
    which we refer to as HD internally,
  • 00:03:31
    which is humanoid version d,
  • 00:03:33
    and that's what you see on our YouTube videos doing the parkour.
  • 00:03:36
    What hardware do you specifically focus on?
  • 00:03:39
    So on Atlas, that robot was more or less finished when by the time I got here.
  • 00:03:44
    So I just did a few upgrades. We upgraded the battery.
  • 00:03:47
    So working on how that battery gets installed and,
  • 00:03:50
    the roll cage that protects that.
  • 00:03:52
    On stretch, I focused on the distal arm,
  • 00:03:55
    which is the end of the robot by the wrist and the gripper as well.
  • 00:03:59
    How does manufacturing differ between robots?
  • 00:04:03
    It's a good question.
  • 00:04:04
    So we have a really broad range of of manufacturing here at the company.
  • 00:04:08
    So on Atlas, we design a lot of metal three d printed parts that are super
  • 00:04:12
    lightweight and very, very strong and stiff.
  • 00:04:15
    Whereas on stretch and spot,
  • 00:04:17
    we're we're designing for very specific processes that scale
  • 00:04:21
    well, towards production.
  • 00:04:24
    Apart from software and electronics,
  • 00:04:26
    how much of mechanics is needed to study to approach robotics?
  • 00:04:30
    Nowadays, robotics is super approachable from all majors.
  • 00:04:34
    You don't kind of have to know everything in every field to do robotics,
  • 00:04:38
    which is really exciting because it it didn't used to be that way.
  • 00:04:41
    If you're really interested in software,
  • 00:04:43
    you can buy pre built kits that let you spend ninety five
  • 00:04:46
    percent of your time coding,
  • 00:04:47
    and you don't have to worry about the mechanisms.
  • 00:04:50
    And likewise,
  • 00:04:51
    if you're really into machining and designing parts,
  • 00:04:53
    there's a lot of microcontrollers that make
  • 00:04:56
    programming really simple, And,
  • 00:04:58
    then you can focus on building cool machines.
  • 00:05:00
    There's a lot you can still do to interact with robots,
  • 00:05:03
    without an engineering degree.
  • 00:05:04
    So, the applications of robotics are only getting larger every single year,
  • 00:05:09
    and there's a lot of roles where you can introduce
  • 00:05:12
    robotics into new fields.
  • 00:05:14
    How can I get started with robots?
  • 00:05:17
    There's a ton of ways to get started with robotics nowadays.
  • 00:05:21
    In in most schools, there's now robotics programs.
  • 00:05:24
    A lot of the principles there really truly apply to the types
  • 00:05:27
    of things we do here.
  • 00:05:28
    If you don't have access to that or really even in general,
  • 00:05:31
    I would encourage you just to take apart everything that your
  • 00:05:34
    parents won't be sad if it gets destroyed.
  • 00:05:36
    If you get excited about it and if you're learning,
  • 00:05:38
    you're doing the right thing.
  • 00:05:39
    So just keep on going down that path.
  • 00:05:41
    But a lot of people here,
  • 00:05:43
    that's kind of the path that we took.
  • 00:05:45
    We've we fell in love with robotics. We do it more.
  • 00:05:48
    We're learning as we're going,
  • 00:05:49
    and eventually that leads to doing exciting work here.
