The Praying Mantis Leaps | ScienceTake | The New York Times

  • 0:06 - 0:07
    (music)
  • 0:08 - 0:09
    Now that's a jump!
  • 0:09 - 0:11
    It would make even
    Michael Jordan proud.
  • 0:13 - 0:14
    Look at it again.
  • 0:14 - 0:16
    See how the abdomen
    curls up
  • 0:16 - 0:17
    as the mantis leaps?
  • 0:18 - 0:21
    That curl
    is the crutial move
  • 0:21 - 0:22
    for a juvenile mantis
  • 0:22 - 0:23
    -- which doesn't have
    any wings yet --
  • 0:23 - 0:25
    when it launches itself
    towards a target.
  • 0:26 - 0:28
    That's what Cambridge
    University
  • 0:28 - 0:29
    researchers found
  • 0:29 - 0:31
    when they analyzed
    the leap
  • 0:31 - 0:33
    using high speed video.
  • 0:33 - 0:35
    The curled abdomen
    changes
  • 0:35 - 0:37
    the center
    of the jumpers mass
  • 0:37 - 0:38
    and it also generates
  • 0:38 - 0:40
    just a little bit
    of spin.
  • 0:40 - 0:42
    It turns out
    that the mantis needs
  • 0:42 - 0:44
    to generate some spin
    first
  • 0:44 - 0:45
    and then correct it
    on the fly
  • 0:45 - 0:47
    in order to make
    an accurate jump.
  • 0:48 - 0:49
    That finding could be
  • 0:49 - 0:51
    very useful for engineers
  • 0:51 - 0:52
    who are now
    trying to figure out
  • 0:52 - 0:54
    how to make
    jumping robots
  • 0:54 - 0:56
    not spin out of control.
  • 0:57 - 0:59
    Look what happens
    to the mantis
  • 0:59 - 1:01
    when glue is used
    to make the abdomen
  • 1:01 - 1:03
    too stiff to curl
    properly.
  • 1:03 - 1:05
    The mantises
    couldn't do it.
  • 1:05 - 1:07
    Sometimes they even
    crashed head on.
  • 1:07 - 1:10
    Of course,
    even without the glue
  • 1:10 - 1:12
    the mantises
    weren't perfect.
  • 1:12 - 1:14
    But then, neither was
    Michael Jordan.
  • 1:22 - 1:22
