A team of researchers has turned to the octopus for inspiration in designing robots for search-and-rescue operations. After disasters like earthquakes or train crashes, robots can be deployed in unpredictable environments to perform critical lifesaving work. According to roboticist Wenci Xin, these robots need to be able to wriggle through narrow cracks and crevices to locate survivors and provide them with essential supplies.
The researchers, including biologist Tamar Gutnick of the Vienna Zoo, studied the behavior of common and Mayan octopuses as they navigated through different-sized holes. The team enrolled a few common octopuses and several Mayan octopuses, each about the size of an apple, in an experiment at a public aquarium in Vienna. By analyzing video footage, they observed the sequence of actions the octopuses took to squeeze through the holes.
The octopuses first reached a single arm through the hole to explore the other side before moving three to five arms to the other side if the hole was big enough. They then used those arms to pull the rest of their body through by pressing back against the partition. If the opening was smaller than the distance between the animal's eyes, Mayan octopuses wouldn't even attempt to slip through, but common octopuses could squeeze through by compressing their body cavity and internal organs.
The researchers found that the octopuses appear to have a sense of their shifting size and shape and space. This ability could be applied to robot design, allowing them to navigate through tight spaces that are currently inaccessible. Wenci Xin is now working on building a robot that mimics the behavior of the octopuses, which is no easy feat.
The study's findings have significant implications for search and rescue operations. According to Mishu Duduta, an engineer at the University of Connecticut, the octopuses' behavior strengthens the case for designing robots that can pull themselves through narrow spaces rather than pushing. This could enable robots to perform delicate work in addition to dangerous, dull, or dirty tasks.
The researchers' goal is to develop robots that can explore areas that are difficult to reach, such as sunken shipwrecks. By studying the octopus's unique abilities, they hope to create robots that can navigate through complex environments and perform critical tasks. The study's results have been published in the Journal of Experimental Biology.
The development of octopus-inspired robots could revolutionize search and rescue operations. With their ability to navigate through narrow spaces and perform delicate tasks, these robots could potentially save lives and improve response times in emergency situations. The researchers' work is an important step towards creating more effective and efficient search and rescue technologies.
