SOFT ROBOTIC ACTUATORS UTILIZING ASYMMETRIC SURFACES
A soft robotic actuator is disclosed. The actuator includes a first portion with a substantially constant profile and a second portion with a regularly varying profile, and bends in a pressure-dependent fashion as the internal pressure within the actuator is increased or decreased.
Gripping mechanism and gripping tool
A gripping mechanism includes: two gripping pieces pivoted relative to each other about a pivot axis; a base supporting at least one of the gripping pieces; a pulley rotatably supported about a rotation axis parallel to the pivot axis; a wire wound around the pulley, causing tensile forces that move the rotation axis in one direction to act, and transmitting a pressing force; and a force-receiving portion receiving the pressing force. The pulley is disposed so that a resultant force of the tensile forces of the wire acting on the rotation axis generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be closed. The force-receiving portion is disposed so that the pressing force applied from the wire generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be opened.
AIR CHUCK
An air chuck includes: a finger support part including a pair of fingers and a pair of lock shafts; a chuck main body part including an operation mechanism operable to open and close the fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a non-lock position so as to render the pair of fingers capable of being opened and closed when the finger support part is linked to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a lock position and locks the pair of fingers so as to render the pair of fingers incapable of being opened and closed when the finger support part is detached from the chuck main body part.
AIR CHUCK
An air chuck includes: a finger support part including a pair of fingers; a chuck main body part including an operation mechanism operable to open and close the pair of fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. The linking mechanisms each include: a linking shaft that extends from the finger support part; a shaft insertion hole formed in a body of the chuck main body part; a catch body that becomes elastically caught on a catch surface of the linking shaft when the linking shaft is inserted into the shaft insertion hole; and a delinking member that is manually operated so as to release the catch body caught on the catch surface when the finger support part is detached from the chuck main body part.
Soft robotic actuators utilizing asymmetric surfaces
A soft robotic actuator is disclosed. The actuator includes a first portion with a substantially constant profile and a second portion with a regularly varying profile, and bends in a pressure-dependent fashion as the internal pressure within the actuator is increased or decreased.
ANTI-BACK DRIVE DEVICE
A rotary drive member drives a driven member. A ring surrounding the driven member has two cam recesses containing lock members between cam surfaces of cam recesses and the ring. Each recess accommodates an associated lock member at different locations where the recess is shallower. Driving the driven member is permitted in a given rotation relative to the ring, but each lock member inhibits rotation of the driven member in the opposite sense. The recesses extend in opposite directions. Coupling between the driven members is free-play whereby reversal in the rotation disengages members and reengages. Protuberances extending into cam recesses retain a lock member associated with one recess at the deeper location permitting movement of the other lock member towards the shallower location. Upon reversal of the rotation, the protuberances retain another lock member at the deeper location permitting movement of one lock member.
Gripping device and robot
A gripping device includes a rotating member having a pinion and rotating about a center axis of the pinion, a drive piezoelectric unit having a vibrating portion that vibrates with expansion and contraction of a piezoelectric material, and a convex portion provided in the vibrating portion, being in contact with the rotating member, and transmitting vibration of the vibrating portion to the rotating member, a rack meshing with the pinion and moving with rotation of the pinion, and a gripping part coupled to the rack, wherein a contact portion in which the convex portion and the rotating member are in contact is located outside of an outer circumference of the pinion in a plan view from a direction of a rotation axis of the rotating member.
MULTI-FINGER ROBOT APPARATUS, ELECTRONIC DEVICE MANUFACTURING APPARATUS, AND METHODS ADAPTED TO TRANSPORT MULTIPLE SUBSTRATES IN ELECTRONIC DEVICE MANUFACTURING
Electronic device manufacturing apparatus and robot apparatus are described. The apparatus are configured to efficiently pick and place substrates wherein the robot apparatus includes an arm component and a blade component. The blade component may comprise two or more end effectors that can retrieve and place two or more substrates at a time. The apparatus can include multiple arm components and multiple blade components. Each blade component can comprise two or more end effectors to carry two or more substrates at one time. The blade components can move independent of one another or may be dependently connected.

A DEVICE FOR ENHANCING A SUBJECT'S GRASPING CAPABILITY
A device for enhancing a user's grasping capability comprises a belt-like support configured to be tightly fitted about a user's part of the body; an articulated gripping element having a plurality of phalanxes: proximal, fixed to the support, intermediate and distal, which are articulated to each other by articular joints; a motor unit fixed to the support; a winding drum; a tendon partially wound on the drum and extending along the phalanxes and the joints, arranged so that, by pulling it from the drum, the phalanxes rotate about respective articular joints and move the articulated gripping element from an extended position to a gripping bow-shaped position, causing a flexion/extension movement of the articulated gripping element, the joints configured so that by releasing the tendon from the drum, the phalanxes rotate about the respective joints and move the articulated gripping element between gripping bow-shaped position and extended position.
