Abstract
The present disclosure provides a robot palm, which includes: a housing having a particle-containing space configured to accommodate particles so that a pressure thereof is changeable; particles filled in the particle-containing space; and an upper membrane installed at an upper portion of the housing and configured to grip an object by changing its shape and rigidity according to a pressure change of the particle-containing space.
Claims5
A robot palm, comprising:
- a housing having a particle-containing space configured to accommodate particles and in which a pressure is changeable;
- particles filled in the particle-containing space;
- and
- an upper membrane installed at an upper portion of the housing and configured to grip an object by changing a shape and rigidity of the upper membrane according to a pressure change of the particle-containing space;
- wherein the housing further includes an air-receiving space configured to accommodate air;
- wherein the robot palm further comprises a middle membrane installed at the housing and provided between the particle-containing space and the air-receiving space;
- and
- wherein the housing includes:
- a base structure having a bottom surface and a sidewall extending upward from the bottom surface and having the air-receiving space provided at an inside thereof surrounded by the bottom surface and the sidewall;
- a middle structure configured to form a side surface between the middle membrane and the upper membrane and having the particle-containing space between the middle membrane and the upper membrane;
- and
- a rim installed at an upper portion of the upper membrane to fix the upper membrane to the middle structure.
