چکیده

In this study, we focus on the intelligent behavior of an octopus and describe the development of a flexible manipulator. By using the developed manipulator, we show that grasping behaviors similar to those of an octopus can be realized by the dynamics of the body without computation in its brain. Keywords-flexible manipulator; octopus; many degrees of freedom; grasping.

A new bio-inspired, antagonistically actuated and stiffness controllable manipulator

Robotic manipulators can be divided into different classes, including discrete, serpentine and continuum robots [1]. Most robots in use today have a number of discrete and usually rigid links connected by simple joints. Our work though has been inspired by biology [2], [3] specifically by the octopus, with its soft tentacles and virtually infinite number of degrees of freedom (DoFs). Biological...

Modeling Flexibility Effects in Robotic Arms Via the Modified 4x4 D-H Homogeneous Transformation

This paper presents a method for the kinematical modeling of robot manipulator arms with flexible members. Development of such techniques are important for the improvement of robotic arms precision performance and their mechanical design. The approach employs the (4X4) Denavit-Hartenberg homogeneous transformations to describe the kinematics of light weight flexible manipulator arms. The method...

Bioinspired locomotion and grasping in water: the soft eight-arm OCTOPUS robot.

The octopus is an interesting model for the development of soft robotics, due to its high deformability, dexterity and rich behavioural repertoire. To investigate the principles of octopus dexterity, we designed an eight-arm soft robot and evaluated its performance with focused experiments. The OCTOPUS robot presented here is a completely soft robot, which integrates eight arms extending in rad...

Controlling the Bending Response of a Multi-Layer Composite Module

Controllable bending stiffness and damping has significant applications in soft robotics, especially for soft slender manipulator arms inspired by octopus tentacles. The bending moment on a solid slender beam is balanced by the sum of moments generated by internal stresses. Resulting stresses are not controllable and decided by the bending curvature, area moment of inertia and elastic modulus o...

Soft Robot Arm Inspired by the Octopus

The octopus is a marine animal whose body has no rigid structures. It has eight arms composed of a peculiar muscular structure, named a muscular hydrostat. The octopus arms provide it with both locomotion and grasping capabilities, thanks to the fact that their stiffness can change over a wide range and can be controlled through combined contractions of the muscles. The muscular hydrostat can b...
