and a lot of work to achieve it. Is there a
way to let current robots help out sooner,
by designing equipment with robots in
mind?
That is another avenue being explored
by Werfel and the RETHi robotics team.
" Instead of bringing the robot up to the
level of the human, we're looking at bringing
tasks down to the level of the robot,
and building something that both robots
and humans can easily operate, " said
Werfel.
The team redesigned several pieces of
important equipment, including a water
filtration component, to make them easier
for robots to repair.
As RETHi enters the last year of its
grant, the SEAS robotics team will put
their technologies to the test, in a combined
physical and virtual simulation of
the scenario of patching a hole left by a
meteorite impact.

Snail-Inspired Robot Could Scoop Ocean Microplastics
The robot's design is based on the Hawaiian apple snail that uses the undulating motion of its foot
to drive water surface flow and suck in floating food particles.
Cornell University, Ithaca, NY
I
nspired by a small and slow snail, scientists
have developed a robot prototype
that may one day scoop up microplastics
from the surfaces of oceans, seas, and
lakes.
The robot's design is based on the
Hawaiian apple snail (Pomacea canaliculate),
a common aquarium snail that
uses the undulating motion of its foot
to drive water surface flow and suck in
floating food particles.
Currently, plastic collection devices
mostly rely on drag nets or conveyor
belts to gather and remove larger plastic
debris from water, but they lack the fine
scale required for retrieving microplastics.
These tiny particles of plastic can
be ingested and end up in the tissues
of marine animals, thereby entering the
food chain where they become a health
issue and potentially carcinogenic to
humans. Plastic waste makes up 80 percent
of all marine pollution, with 8 to 10
million metric tons of plastic ending up
in the ocean each year, according to the
United Nations Economic and Social
Council.
