A Dynamic Model of the Octopus Arm. I. Biomechanics of the Octopus Reaching Movement
The octopus arm requires special motor control schemes, because it consists almost entirely of muscles and lacks a rigid skeletal support. Here we present a 2D dynamic model of the octopus arm to explore possible strategies of movement control in this muscular hydrostat. The arm is modeled as a multi-segment structure, each segment containing longitudinal and transverse muscles and maintaining ...

متن کاملDynamic model of the octopus arm. II. Control of reaching movements.
The dynamic model of the octopus arm described in the first paper of this 2-part series was used here to investigate the neural strategies used for controlling the reaching movements of the octopus arm. These are stereotypical extension movements used to reach toward an object. In the dynamic model, sending a simple propagating neural activation signal to contract all muscles along the arm prod...
متن کاملSeasonal Variations of Fat and Fatty Acid Composition in Muscle Tissues of Mediterranean Octopuses
The effects of seasons on lipid and fatty acid profiles of muscle types (mantle and arm) of Mediterranean octopuses (common octopus-Octopus vulgaris and musky octopus-Eledone moschata) were investigated. The results showed that lipid levels ranged from 0.75% to 1.60% in both muscle types of octopuses which were considered as lean. Lipid levels in mantle tissues of both octopus species w...

متن کاملA soft body as a reservoir: case studies in a dynamic model of octopus-inspired soft robotic arm
The behaviors of the animals or embodied agents are characterized by the dynamic coupling between the brain, the body, and the environment. This implies that control, which is conventionally thought to be handled by the brain or a controller, can partially be outsourced to the physical body and the interaction with the environment. This idea has been demonstrated in a number of recently constru...
