Mechanical finger

摘要

A mechanical finger comprises at least two phalanges. The phalanges have tubular bodies made of a semi-rigid material. One phalange is adapted to be secured to a base. Another phalange is connected to an adjacent phalange for pivoting movement with respect to the adjacent phalange. A skeleton member in the tubular bodies of the phalanges moves to actuate the pivoting motion of the phalanges with respect to one another. The skeleton member is connected to a degree of actuation to cause the pivoting motion of the phalanges with respect to one another. An assembly is also provided. The assembly comprises at least two of the mechanical finger, a palm actuator comprising a base for connection of the base phalange of each mechanical finger, and at least one degree of actuation connected to the skeleton member. The degree of actuation causes a grasping movement of the mechanical fingers.

1. A mechanical finger comprising:
at least two phalanges, with the at least two phalanges each made of a semi-rigid material forming a tubular body, one of the at least two phalanges being a base phalange adapted to be secured to a base; another of the at least two phalanges being an end phalange, the end phalange being pivotally connected to an adjacent one of the at least two phalanges for pivoting movement with respect to the adjacent one of the at least two phalanges; a skeleton member received in the tubular bodies of the at least two phalanges and movable to actuate the pivoting motion of the at least two phalanges with respect to one another, the skeleton member adapted to be connected to a degree of actuation for causing the pivoting motion of the at least two phalanges with respect to one another; and a degree of flexibility in all directions for the assembly of at least two phalanges and skeleton member therein, whereby the mechanical finger is compliant in all said directions.
