An apparatus including a plurality of robot arm links movably connected to one another, where a first one of the robot arm links includes a frame, where the frame has a first end movably connected onto a second one of the robot arm links; and at least one vibration damper arrangement on the frame of the first robot arm link, where the at least one vibration damper arrangement includes at least one viscoelastic element connected to the frame of the first robot arm link by a connection such that, as the frame of the first robot arm link experiences vibrations, the at least one viscoelastic element dampens the vibrations in the frame of the first robot arm link based upon viscoelasticity and the connection of the at least one viscoelastic element to the frame of the first robot arm link.

Method for producing a cushion with a casing made of an airtight casing material and a flexible, polydirectionally air-permeable filling body which is arranged in the casing and which is materially connected to the casing. The method includes at least the following steps: coating a first mold cavity of a molding tool with a curable, flowable and/or sprayable plastic material to form a first casing shell, coating a second mold cavity of the molding tool with the curable, flowable and/or sprayable plastic material to form a second casing shell, inserting a pre-produced filling body into the first casing shell located in the first mold cavity, and joining together of the first and second casing shells located in the first mold cavity and in the second mold cavity before the plastic material cures or fully reacts.

A movement assistance device includes: a back plate that is fitted onto the back of a wearer; a back frame that has an elongated shape and is supported by a rotating shaft fixed to the back plate so as to be rotatable in a plane parallel to the back plate; a side frame that is rotatably supported by a rotating shaft fixed to the back frame and parallel to the longitudinal direction of the back frame and extends from the back frame toward the vicinity of the side waist of the wearer; a thigh holding portion that is fitted onto the anterior thigh of the wearer; and a drive portion that is connected to each of the side frame and the thigh holding portion and generates force that increases the angle between the side frame and the thigh holding portion.

A strut suitable for use in parallel manipulator and other applications utilizes an actuation member that is subjected to a quasi-static axial tensioning force to effectively preload the strut to provide axial stiffness and bending flexibility at one or more ends of the strut.

A robot system includes an end effector that is able to work on a workpiece, a support part configured to support the end effector in a state in which the end effector is displaceable, a first driving part configured to drive the end effector via the support part with a first stroke, a detector configured to detect a position of the end effector, and a second driving part that is disposed between the support part and the end effector and that is configured to drive the end effector with respect to the support part with a second stroke smaller than the first stroke based on a position information of the end effector detected by the detector.

An autonomous mobile robot is provided. The autonomous mobile robot includes an upper module including a cargo space provided therein, and a cover, a lower module positioned under the upper module and providing a driving force, a driving module provided in the lower module, and a control unit that controls an operation of the driving module, in which the driving module includes a plurality of pairs of wheels capable of asynchronously contacting a road surface or ground so as to overcome a step or a stair.

A work device includes a work device body and a contact preventer. The work device body includes a linear motion unit having three degrees of freedom and a rotary unit having three degrees of freedom. An end effector is mounted on an output portion of the rotary unit. The contact preventer separates a working region in which the work device body is installed, from a non-working region outside the working region. The contact preventer includes: an entry allowing portion allowing an object to enter the working region therethrough; and an entry allowing portion entry detection sensor configured to detect entry of an object into the working region through the entry allowing portions.

An apparatus for picking a product, including: at least one vacuum cup including at least one axis passing through the at least one vacuum cup; and at least one damping device surrounding at least a portion of the at least one vacuum cup in a radial direction orthogonal to the at least one axis. The at least one vacuum cup is arranged to create negative pressure and adhere, with the negative pressure, the at least one sheet of material to the at least one vacuum cup. The at least one damping device is arranged to contact the at least one sheet of material to limit displacement of the at least one sheet of material with respect to the at least one vacuum cup.

A modular robotic snake-arm assembly is described which is animated principally by an articulated drive shaft that threads the length of the snake-arm. The articulated drive shaft is driven by a motor in the fixed base. One or more clutch mechanisms in each segment couple with the articulated drive shaft so as to cause all snake arms further from the base to reorient in either one or two angles, in either direction. Snake-arm segments can be coupled end-to-end to form a robotic snake arm of great length.

Disclosed is a hexapod system including first and second supports and six linear actuators. Each linear actuator has an articulated end on the first and second supports, with a swivel connection with a force-absorbing structure embedded in the first support and a swivel connection to linear actuators articulated on the first support, and one of the first and second supports includes a connector that cooperates with the force-absorbing structure. The connector cooperates with a second force-absorbing structure of a second hexapod system, and the two hexapod systems mount in series.
