Title:
YIELDING ROBOTIC CLAW BASED ON COMPRESSION CHAMBERS
Document Type and Number:
WIPO Patent Application WO/2020/210886
Kind Code:
A3
Abstract:
A new structural arrangement is disclosed for a soft robotic claw with compression chambers that provides a fully yielding body that is able to grip, release and hold objects of different shapes and sizes. Said robotic claw has one or more internal fluid chambers, the shape of which can be adjusted as a function of the desired deformation of the internal chamber, such that the region of greatest volume is the region in which the greatest deformation is desired in order to hold objects. Said robotic claw comprises the body (1), which is made entirely of flexible materials. Said body (1) comprises a flat base (3) from which projects a thick wall (2) that describes a geometric shape such as a tube, the cross section of which can be circular, square or of any other shape as a function of the intended application, without thereby moving outside the scope of the invention disclosed herein. Said thick wall (2) has at least one internal fluid-filled chamber (21). The gripping forces applied to the object inserted into the cavity (4) are determined by the pressure applied in the chambers (21), considering that the thickness of the inner wall (2") is less than the thickness of the outer wall (2').
