How to make artificial octopus arms is now a dream of scientists.
Niralis or kinavalli are a favorite subject of scientists. Mollusca, a class that includes the powerful and intelligent octopuses, and mammals, a class that includes humans, evolved from a common ancestor about 60 million years ago. So octopuses are the darlings not only of zoologists, but also of chemists, physicists and now robotics. Have you read what was written earlier in this column about octopuses who dream? Not only the dreaming brain, but also the hands of eight-armed octopuses are very distinctive. The idioms like Niralikaikal and Niralipipdutum in Malayalam are due to the characteristics of Niralikai. How to make artificial octopus arms is now a dream of scientists.
When we think of robots or robot walking and robotic dance, what comes to our mind are inflexible, muscle bound movements. This lack of flexibility is a disadvantage in robotics research. Octopuses have a very flexible boneless body with suckers and hands that can suck in air and tighten their grip. What if we could bring these flexible hands to robots? Things may be small or complex; These octopus-armed robots are no small matter.
Like a wave curling up from the bottom and holding things ‘Sucker’ Researchers at Beijing University in China are trying to transfer the skills of octopuses to robots by sticking them in their mouths without even taking a step. Not only that, the octopus’s arms aren’t much controlled by its brain. Most of the hands are controlled by the nerves in the octopus arms. Such a biosignaling system is easy to integrate into robotics because very few instructions travel from its head to its hands.
An octopus hand, a finger that controls the octopus hand. That’s how this new octopus robot ‘Octobot’ was created. The octopus hand is made of silicone. It consists of wires made of metal alloys that are liquid at normal temperature and solid when cooled. Standard silicon chips and these wires can be combined to form an electronic network that mimics the nervous system of an octopus. Suckers and temperature sensors are placed at the tip of the octopus arm. This entire octopus arm is operated wirelessly with a one-finger glove. The movement of the fingered hand, its speed and how it turns will be captured by the Octopus. Niralikai will work accordingly. Acting like an octopus arm, this ‘octorobo’ can extend its arm up to one and a half times to grasp its prey. Sensors are also placed on the finger so that the operator wearing the finger knows when the victim is being pulled and stuck.
It can operate successfully in water and air ‘Octorobo’ Soft robotics has the potential to revolutionize the field. Scientists believe it could have many uses, from marine to medical. Moreover, the fact that human-robot interaction is possible in these robotics without interfaces and that all related concepts are bio-inspired from Octorobo increases the possibilities of use of Octorobo many times over.
