Abstract
A mechanical hand comprising a housing with a first sliding actuation member and second sliding actuation member, at least two elongate, bendable members comprising a proximal phalanx and a distal phalanx, a relatively stationary member attached to the housing, a primary tension member projecting through the housing and at least through the second sliding actuation member, and a set of primary tendons and a set of secondary tendons. The primary tendons have first and second ends, with the primary tendon first end secured to the first slidable actuation member, and with the primary tendons extending through the bendable members. The primary tendon second end is secured to the distal phalanx. Each secondary tendon has first and second ends. The secondary tendon first end is secured to the second slidable actuation member. The secondary tendons extend through the bendable members. The secondary tendon second end is secured to the proximal phalanx. A method for having the mechanical hand of this invention exhibit a conformable grasp is also disclosed.
