Researchers are from the Hebrew University of Jerusalem.
The study on the how the octopus moves, having such a soft body is the first detailed study.
The video revealed the simplicity of their motion, researchers found that the octopus choose which arm to use to push themselves along.
Engineers have great interest on how the octopus control and move as they are aiming to design biologically inspired robots.
Dr Guy Levy, one of the researchers in the study said, “People want to build soft robots for medical purposes and rescue operations.”
Researchers explained that the octopus inspired arms would not be limited by fixed joints. This kind of robot having such arms would be able to access narrow spaces, and difficult to reach places, so that it can help people trapped in the collapse of the building or any other disaster.
To understand the movement of the octopus to find out the secrets Dr Levy and his colleague Prof Benny Hochner videoed the octopus underneath and then studies the movement of the animal frame by frame.
Guy Levy said that the octopus has found a very simple solution to the problem of soft body.
Researchers said that after the analysis they found that by shortening and lengthening each arm pushed the body in one direction.
Dr Levy said, “So the octopus only has to decide which arm to use for the pushing – it doesn’t need to decide which direction this arm will push.” It has “found a very simple solution to a potentially complicated problem – it just has to pick which arm to recruit.”
The creature is able to push off any of their eight limbs and hence they are able to move in any direction no matter which way their body is facing.
There is no rhythm and pattern to their undulating limb movements.
The next step is to delve into the internal circuitry of the octopus nervous system, as the scientists want to find out how this coordinated crawling is controlled.
Dr Levy said, every time they try to understand new concepts in the octopus, there are new surprises.
