Festo presents a bionic gripper called the OctopusGripper, which is derived from an octopus tentacle. Not only can the flexible silicone structure grip softly and securely – it also fulfils the strict criteria of a soft robotics component.
From sensitive to powerful – the pneumatic lightweight robot can fluently perform the natural movements of an elephant’s trunk and an octopus’s tentacle. The special 3D textile knitted fabric around the bellows structures gives the kinematics tremendous power potential.
The octopus is a fascinating creature. As it has no skeleton and is made almost entirely of soft muscle, it is also extremely flexible and manoeuvrable. This not only means it can swim agilely in all directions, but also grip a wide range of objects in a form-fitting manner.
The OctopusGripper now takes makes this phenomenon its own.The gripper consists of a soft silicone structure, which can be pneumatically controlled. If compressed air is applied to it, the tentacle bends inwards and can wrap around the respective item being gripped in a form-fitting and gentle manner.
