The tapering also allowed the arm to squeeze into confined spaces and retrieve objects. The researchers successfully tested the device on many different objects, including thin plastic sheets, coffee mugs, test tubes, eggs, and even live crabs. By changing the pressure and vacuum, the arm can attach to an object, wrap around it, carry it, and release it. Researchers control the arm with two valves, one to apply pressure for bending the arm and one for a vacuum that engages the suckers. Xie is the co-inventor of the Festo Tentacle Gripper, which is the first fully integrated implementation of this technology in a commercial prototype.

By changing the pressure and vacuum, the arm can attach to any object, wrap around it, carry it, and release it. Octopus tentacles are incredibly strong and powerful tools that not only help them to catch prey but also fend off predators too.
The soft robot is controlled with two valves, one to apply pressure for bending the arm and one for a vacuum that engages the suckers. “Although our design is much simpler than its biological counterpart, these vacuum-based biomimetic suckers can attach to almost any object.” “We mimicked the general structure and distribution of these suckers for our soft actuators,” said co-first author Zhexin Xie, a PhD student at Beihang University. Next, the team looked at the layout and structure of the suckers (yes, that is the scientific term) and incorporated them into the design. The researchers began by studying the tapering angle of real octopus arms and quantifying which design for bending and grabbing objects would work best for a soft robot. The research is published in Soft Robotics. “Our research is the first to quantify the tapering angles of the arms and the combined functions of bending and suction, which allows for a single small gripper to be used for a wide range of objects that would otherwise require the use of multiple grippers.” “Most previous research on octopus-inspired robots focused either on mimicking the suction or the movement of the arm, but not both,” said August Domel, a recent PhD graduate of Harvard and co-first author of the paper.

Experience increased mobility with this innovative design that’ll keep you from burning your fingers.The soft robot is controlled with two valves, one to apply pressure for bending the arm and one for a vacuum that engages the suckers. Having 8 arms, octopuses can be referred to as octopods while cuttlefishes and squids, having a total of 10 arms, are referred to as decapods. With a tentacle appendage looping into itself and suckers dispersed through the loop, the tentacle carb cap is very easy to grip. Direct Downloads Version 6.3.
