CylindricalShell Class Reference

CylindricalShell represents a cylindrical shell that consists of two colinear cylinders. A shell consists of an inner and an outer cylinder. The portion of the object to be grasped must fit inside the inner cylinder, and the radius of that cylinder must be no larger than the maximum hand aperture. The gap between the inner and outer cylinder must be free of obstacles and wide enough to be able to contain the robot fingers. More...

Detailed Description

CylindricalShell represents a cylindrical shell that consists of two colinear cylinders. A shell consists of an inner and an outer cylinder. The portion of the object to be grasped must fit inside the inner cylinder, and the radius of that cylinder must be no larger than the maximum hand aperture. The gap between the inner and outer cylinder must be free of obstacles and wide enough to be able to contain the robot fingers.
