Development of Sensorized Arm Skin for an Octopus Inspired Robot – Part III: Biomimetic Suckers
Biomechanical properties of squid suckers have been studied. The stiffness of the sucker rings was measured. Sucking force at sea level and maximum possible sucking force were obtained by using specially-designed tensile tests. Two biomimetic passive suckers were developed based on the studies of the squid sucker. The first one was a direct copy of the squid sucker while the second one is a much more simplified version, a non-stalked sucker like the octopus suckers. The second design works very effectively and has been implemented in the prototype skin of the octopus arm.
