3D reconstruction of octopus arm swimming motion
Arm swimming in the octopus is a mode of locomotion that is used by the animal primarily for hunting, defence, or escape. The motion, in general, is characterized by a fast closing of the arms and a slow opening of the arms, resulting in a considerable propulsive power. The movement has previously been discussed, however the detailed kinematics is still unknown. For that, we investigated in det...
متن کاملSoft 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...
متن کاملDesign of a biomimetic robotic octopus arm.
This paper reports the rationale and design of a robotic arm, as inspired by an octopus arm. The octopus arm shows peculiar features, such as the ability to bend in all directions, to produce fast elongations, and to vary its stiffness. The octopus achieves these unique motor skills, thanks to its peculiar muscular structure, named muscular hydrostat. Different muscles arranged on orthogonal pl...
متن کاملOctopus arm kinematic analysis for use in multi-arm underwater robotic swimmers
The extraction of accurate kinematic information of animal appendages is of great importance for many biologically-inspired robotic applications. Octopus arm trajectories during a two-stroke arm-swimming motion have been initially analyzed through a vision-based 3D process, that reconstructs the arm spatial configurations and captures their 3D motion; this work is presented in [Kazakidi et al, ...
متن کاملFish-Inspired Swimming Simulation and Robotic Implementation
This paper describes our efforts to develop a Digital Fish Simulator (DFS), particularly aiming at creating a controlled kinematic centered environment to further shed light on how to design and control artificial fish robots. Compared to a 3D simulator for autonomous robotic fish by Liu and Hu, an improved body wave equation capable of multimodal swimming motions is adopted in our simulator an...
