As in the movies, a vision system that can move in any direction will peer around, under, and into space equipment
NASA has adopted Israeli “Martian”-style technology
for a robot to inspect equipment in deep space. The Visual Inspection Poseable
Invertebrate Robot, or VIPIR, is an articulating borescope tool designed to
deliver near and midrange inspection capabilities in space to enable repairs of
equipment using robots on unmanned spaceships — and a tiny camera from Israeli medical
device company Medigus will be giving VIPIR its power of vision, allowing
technicians on Earth to get a close-up look at equipment.
It’s like “War of the Worlds,” where Martians send
machines down to Earth with roving “eyes,” cameras attached to the end of a
flexible tube, nearly a meter (3 feet) long, to report back to the Martians on
what is going on Earth. In the films (1953 and 2005) and in the original 1898
Wells book, the aliens use machines with cameras to peer around, under, and
into any and everything, seeking out humans to destroy.
The tiny camera NASA will be using for its
other-worldly robot project, called the micro ScoutCam 1.2, comes from the
world of medicine, not Mars, and it’s already in space. It’s made by Medigus,
an Israeli company that specializes in developing minimally invasive
endosurgical tools and imaging solutions. For example, Medigus makes a system
that enables doctors to examine, diagnose, and treat GERD (Gastroesophageal
Reflux Disease) — via the mouth, allowing patients to be treated without the
need for surgery. The Medigus MUSE system for GERD includes a surgical stapler,
ultrasonic sights for accurate positioning, and a miniaturized video camera,
all in a single instrument.
MUSE is a clear precursor to the camera technology
being used in VIPIR. The MUSE camera also sits on the end of a flexible tube,
and can be controlled by doctors via a console instrument. The MUSE camera, at
3 millimeters diameter, is a marvel of technology, but the camera being used in
VIPIR, at 1.2 millimeters, is the smallest in the world. The camera can deliver
back to Earth a ~100-degree field-of-view image with a 224 x 224 pixel (0.05
megapixel) resolution. While the number of pixels may sound small compared to
today’s commercially available digital cameras — it’s ideal for the close-range
inspection jobs VIPIR will be doing, NASA said. With the Medigus camera,
mission controllers can zoom in to resolve worksite details as tiny as 0.02
inch – thinner than a credit card. The tube itself can rotate up to 90 degrees
in four opposing directions.
VIPIR and its attached Medigus camera are to be
used on the International Space Station orbiting Earth. It was sent last week
with the European Automated Transfer Vehicle-5, which docked with the
space station. VIPIR will allow mission controllers to try out various
remote-repair technologies they have been developed over the past several years
by NASA’s Robotic Refueling Mission (RRM), and Dextre, the Canadian Space
Agency.
“NASA is steadily maturing a set of robotic
technologies that could help prolong the lives of satellites in orbit, thereby
providing new capabilities for the Agency,” said Benjamin Reed, deputy project
manager of NASA’s Satellite Servicing Capabilities Office. “Medigus’ micro
ScoutCam 1.2 met the requirements for VIPIR’s borescope camera, and will
demonstrate inspection capabilities once Robotic Refueling Mission operations
begin.”
