Methods, systems, and methods of manufacture for soft robotic actuators are described herein. In one aspect, a soft robotic actuator can include an elastomeric material defining a cavity; a volume of liquid metal (LM) positioned within the cavity; and an energy source coupled to the LM, where the energy source is adapted or configured to alter a temperature of the volume of LM, whereby altering the temperature of the volume of LM initiates an actuation of the elastomeric material.

The inventive concept relates to a wearable hand robot mounted on a finger to bend the finger by an external force transmitted through a wire. The wearable hand robot is capable of preventing an injury to a user's hand by the wire, achieving simplification of the structure of a finger cap and an improvement in a wearing sensation, and stably moving the finger while having a tactile sensation.

A link, a robotic arm and a surgical robot are provided. The link is configured in a rod shape and defines an inner cavity extending in a length direction of the link, and wherein at least a part of the inner cavity is seamlessly enclosed in a circumference perpendicular to the length direction of the link. The robotic arm includes at least one link. The surgical robot includes at least one robotic arm.

An embodiment includes an exoskeleton robotic system including: a first linkage; a bearing coupled to the first linkage; a joint including a motor configured to move the first linkage along the bearing; an axial load sensor configured to sense an axial force transmitted to the axial load sensor via the joint, the axial force including one of tension or compression but not torque; a bracket including first and second bracket locations and first and second arms; and a housing that includes at least part of the joint and which couples the bracket to the bearing. The bracket couples to the housing at the first bracket location and couples to the axial load sensor at the second bracket location. The first arm couples the second arm to the first bracket location, and the second arm couples the first arm to the second bracket location.

A gripper finger (1) for a gripper device having a monolithic elastic structure comprising an inside arm (2) having a first folding point (8) forming an angle C; an outside arm (3) having a second folding point (9), wherein the inside arm or the outside arm comprises a gripping surface for gripping an object; a base portion (4) having a first base end (10), from which the inside arm (2) is extending, and a second base end (11), from which the outside arm (3) is extending; a tip portion (6) where the end of the outside arm (3) and the end of the inside arm (2) are connected to each other; a support arm (5) extending from the first base end (10) to the second folding point (9); the gripper finger further comprises an angle E between a first part of the outside arm (3), arranged between the second base end (11) and the second folding point (9), and the support arm (5), wherein the angle E is at least 11.5 degrees.

A device for a microactuator comprises a body (110), two terminal members (20, 22) articulated (136, 138) on the body (110), which are situated on one side of the latter, and two deformable bowl-shaped walls (120, 122) which face one another. The walls are configured to house an actuator, with two respective first edges (1202, 1222) of these walls (120, 122) situated on one side being fixed (1264) to the body (110), whereas two respective second edges (1204, 1224) of these walls (120, 122) situated on another side move consecutively to a deformation of the walls (120, 122) under the effect of the actuator. This movement is transmitted by two arms (132, 134) which terminate at the two respective terminal members (20, 22).

Disclosed is a gripper including a pair of main bodies each having an internal space and spaced apart from each other, a pair of openings provided at ends of the pair of main bodies, a pair of moving bodies protruding from the ends of the pair of main bodies through the openings, a pair of inner bodies fixed in the internal space of the pair of main bodies, and a pair of springs configured to be compressed between the inner body and the moving body.

An inspection robot, and methods and a controller thereof are disclosed. An inspection robot may include an inspection chassis including a plurality of inspection sensors and coupled to at least one drive module to drive the robot over an inspection surface. The inspection robot may also include a controller including an inspection data circuit to interpret inspection base data, an inspection processing circuit to determine refined inspection data, and an inspection configuration circuit to determine an inspection response value in response to the refined inspection data. The controller may further include an inspection response circuit to, in response to the inspection response value, provide an inspection command value while the inspection robot is interrogating the inspection surface.

A mechanical finger for a mechanical hand, has: a proximal phalanx pivotably mountable to a support of the mechanical hand to pivot relative to the support about a finger pivot axis; a distal phalanx pivotably connected to the proximal phalanx via a first living hinge to pivot relative to the proximal phalanx about a first pivot axis; and a skeleton member pivotably connected at one end to the distal phalanx via a second living hinge to pivot relative to the distal phalanx about a second pivot axis offset from the first pivot axis and at another end operatively connected to an actuator of the mechanical hand to be selectively movable by the actuator to pivot the distal phalanx relative to the proximal phalanx and to pivot the distal phalanx relative to the support when the finger is in use.

An actuated or mobile device such as a mobile robot or robotic muscle is provided, wherein mobility may be enabled by means of novel models of inchworm actuator positioned to tighten, loosen, move, or pull on one or more strings or tendons to directly or indirectly effect motion. The clamp elements of the inchworm actuator may include the novel optimization of being H-shaped and/or including a ‘beak’ element. Inchworm actuators tightening and/or loosening strings or tendons may cause ‘foot’ elements to rotatably extend from or tuck into a surface of the device, enabling the device to pull itself along. The device may include one or more moveable joints implemented as a bow joint. One or a grouped set of inchworm actuators pulling tendons may be used to rotate an axle, particularly for implementing a robotic joint around the axle.
