Imagine being trapped under the rubble of a collapsed building after a flash flood, with wet concrete, wood, and all kinds of debris blocking every direction, with only tiny gaps in between the mountain of jagged objects leading to the outside world.
You cry out for help, hoping for anyone to find you. Eventually, you finally see something climb inside the rubble for you, and it's a... cyborg cockroach with a scuba suit?
Unbeknownst to you, this rescue insect could potentially be your saving grace.
Researchers in Singapore have published a study detailing how they have developed diving suits for cyborg cockroaches for potential use in search-and-rescue missions that involve tight, water-filled spaces that humans cannot access, as well as other precise aquatic applications like pipe inspection.
It sounds like something from the video game Half-Life 2, but it's really quite ingenious when you break it down.
Cyborg insect technology has been a key point of scientific research for many years now; as opposed to traditional robot machinery, insects don't need huge batteries and are very flexible.
However, there is one caveat that limits their potential use cases: Most insects only breathe air with a complex respiratory system, which we'll talk about soon, and this has limited many of their potential applications for exploration in aquatic or semi-aquatic environments... until now.
The species of cockroach specifically used for the design in this study was the Madagascar Hissing Cockroach, a.k.a. Gromphadorhina portentosa.
This insect breathes through a system of spiracles, which are essentially holes on its body that allow air to directly interact with the insect's tissues, on the sides of its thorax, divided into the prothoracic (front thoracic segment) and mesothoracic (back thoracic segment) spiracles.
In order to be used as an aquatic exploration biological robot, it needed to be fitted with some specialized hardware that allowed it to operate underwater. And the researchers of this study have done just that.
How were the roaches turned into cyborgs?
G. portentosa individuals used in this study were fitted with a backpack unit that had wireless communication and the ability to control the roaches' movements via pulses of electrical signals, essentially making them RC roaches.
In addition to the backpack, they were given a flexible resin diving suit that enclosed their abdomen with a 3D-printed oxygen generator inside it. This oxygen generator used a manganese dioxide catalyst to speed up the decomposition of liquid hydrogen peroxide.
The resulting decomposition reaction released oxygen, which was then supplied to the roaches through silicone tubes that were attached to the roaches' spiracles. The tubes had to be designed differently for both the prothoracic and mesothoracic spiracles because of their anatomical differences. However, when the design was put to use, the roaches were able to remain active underwater for up to a whopping three hours.
How useful is this?
During the testing phase, the cyborg scuba roaches were able to squeeze through tiny gaps two centimeters tall while underwater and make it to the other side. This makes an interesting case for future aquatic exploration using cyborg insects.
Thoughts and retrospective:
The concept of cyborgs actually being real is pretty mind-boggling, especially ones that could potentially be used to save many lives.
Questions to consider:
What is the ethical dilemma of using a living creature as a robot against its will?
Is the cockroach aware that it's being controlled?
Will this technology eventually evolve to be used for more complex organisms, potentially even humans?
The implications of that are pretty existential.
As of now, these cyborg scuba roaches are without a doubt a technological and biological breakthrough, one that has given an unassuming little bug a big responsibility.
