SYSTEM FOR CONTROLLABLY ESTABLISHING ADHESION OR FRICTION WITH AN EXTERNAL BODY
20220203556 · 2022-06-30 ·

A system for controllably establishing adhesion or friction with an external body. The system comprises a channel member and an interface member. The channel member comprises fluidic channels communicating positive or negative pressure. The interface member is disposed over the channel member. The interface member comprises exposed portions and topographic members. The exposed portions are flexible and exposed to the pressure communicated by the fluidic channels. The exposed portions deform under the pressure communicated by the fluidic channels and reform in the absence of the pressure communicated by the fluidic channels. The exposed portions assume a convex shaped under positive pressure and concave shaped configuration under negative pressure. The topographic members are provided over the exposed portions. The topographic members move based on the deformation of the exposed portions. The strength of adhesion varies based on the deformation of the exposed portions.
