A group of scientists led by the College of Bristol has been learning a fish sensory organ to be able to acquire perception into collective habits, which could possibly be used for underwater robots.

The main focus of the analysis was the lateral line organ present in African cichlid fish and nearly all different fish species. This organ permits fish to precisely sense water strain and detect exterior elements like different fish, adjustments in water movement, predators, and obstacles.

Lateral Line System in Fish

The lateral line system spans the top, trunk, and tail of fish and consists of mechanoreceptors often known as neuromasts. These receptors will be positioned inside subdermal channels or on the floor of the pores and skin.

Elliot Scott of the College of Bristol’s Division of Engineering Arithmetic was lead writer of the research.

“We were attempting to find out if the different areas of the lateral line — the lateral line on the head versus the lateral line on the body, or the different types of lateral line sensory units such as those on the skin, versus those under it, play different roles in how the fish is able to sense its environment through environmental pressure headings,” he mentioned.

“We did this in a novel way, by using hybrid fish, that allowed for the natural generation of variation.”

The researchers discovered that the lateral line system across the head has a major impression on the fish’s potential to swim in a bunch. A better variety of subdermal neuromasts results in nearer swimming, whereas extra floor neuromasts end in extra separated swimming.

Scaling Up By way of Simulation 

The mechanisms behind the lateral line system have been additionally proven to work at bigger scales by way of simulation. This might result in the event of a low-cost strain sensor for underwater robotics, particularly for swarm robotics, the place value is a serious concern.

“These findings provide a better understanding of how the lateral line informs shoaling behavior in fish, while also contributing a novel design of an inexpensive pressure sensor that could be useful on underwater robots that have to navigate in dark or murky waters,” Elliot mentioned.

The group will now look to develop the sensor even additional and combine it right into a robotic platform to assist a robotic navigate underwater.
