The robotics industry has advanced tremendously in
recent years with several cutting edge developments. Now, researchers have
created a hydrogel-based, light-powered robot that swims in response to a
direct light source.
This particular robot, the OsciBot, is attracted to
and only powered by a constant visible light source. It doesn’t require a
battery pack or power tether of any kind. This type of technology could revolutionise
the maritime industry in terms of energy harvesting and propulsion in the future.
When we look at modern
naval vessels, the larger and more glamorous ships generally take centre stage
including the massive aircraft carriers and the ever-dangerous nuclear
submarines. However, if it weren’t for frigates, these super ships would be unable
to safely take on the open oceans.
Frigates are also
called the “eyes of the fleet” and serve as multi-purposed warships.
Their size is essentially in-between a smaller corvette and a larger destroyer where
they act independently of the fleet and can free up larger ships in
While frigates weren’t
suitable to fight with the rest of the fleet in normal battles, they were the
perfect solution to long-range solo missions. This included exploration,
patrols, escorts, blockades, anti-piracy and anti-slavery missions among
