A robotic wrist for a robotic arm includes a hybrid differential with a first cam, a second cam, a first differential input, and a second differential input. The first cam and the second cam are disposed about first and second pivots oriented along a first rotational axis. An abduction output is coupled to the second cam and has a second rotational axis transverse to the first rotational axis. The robotic wrist includes a first actuator, a second actuator, a first link coupling an output of the first actuator to the first differential input, and a second link coupling an output of the second actuator to the second differential input. Synchronous motion of the actuators causes flexion of the abduction output about the first rotation axis, and asynchronous motion of the actuators causes abduction motion of the abduction output about the second rotation axis.

A mechanical hand mimics a human hand having similar degrees of freedom and sensory abilities while appearing visually similar to human hand. The mechanical hand comprises a mechanical hand skeleton and resilient elastomer (e.g., silicone) skin that fully encloses the mechanical hand skeleton. The mechanical hand skeleton may advantageously be molded directly into the resilient elastomer (e.g., silicone) skin such that the hand appears, moves, and feels very similar to a real human hand. The mechanical hand may have applications in robotics, for example as an end-of-arm tool or end effector, or may have other applications. Robotic applications may include prosthetics applications.

Mechanical hand, useful in robotics

A flexible joint includes a plurality of links, a plurality of flexures, and at least one cable which can be tensioned or relaxed to cause a bending about a plurality of axes. The links may include a base link; a last link; and a plurality of intermediate links, coupled together by the flexures such that the plurality of intermediate links, the first link, and the last link form a chain of links having the base link at a first end of the chain and the last link at a second end of the chain and each of the plurality of intermediate links is coupled to two other ones of the plurality of links by two flexures. The cable(s) extend through cable pass-through-holes in the links. The links may comprise disks with sloped faces, and may be rotational offset from another around a longitudinal axis. The flexures may comprise living hinges.

A detachable mechanical eye cartridge includes a plurality of links, a plurality of couplers, a plurality of electronic connection points, and at least one mechanical eye that can be rotatably actuated in at least two rotational degrees of freedom. The detachable mechanical eye cartridge may include actuators for actuating the eye, eyelid structures, an actuator for actuating the eyelid structures, and imaging sensors within the mechanical eye. The detachable mechanical eye cartridge may include one or two mechanical eyes and related structures and may include a set of magnetic couplers that couple to magnets on a robotic head frame to which the detachable mechanical eye cartridge may couple. The detachable mechanical eye cartridge may also have a set of mechanically coupled linkages for controlling the pitch of each mechanical eye with minimal backlash.
