A device for the maintenance of an overhead line system of a track has a handling device and a displacement device. The displacement device serves to displace the handling device between a transport position and a working position. In the working position, the handling device reaches the overhead line system and is able to perform maintenance work by way of a tool. At least one sensor serves for controlling and/or monitoring the handling device. The device thus enables a simple, efficient and safe maintenance of the overhead line system.

A device for treating objects, wherein a gap is formed between two wall sections of a treatment chamber. At least one respective component of at least one first and one second working device which can move along the gap, extends from an outer region outside of the treatment chamber through the gap into the treatment chamber. A covering assembly seals the gap in the wall of the treatment chamber, apart from a first through opening and a second through opening, through which the component of the first working device or the component of the second working device extend, and which follow a movement of the component of the first working device or the component of the second working device along the gap. A covering band running on the gap is secured to a first and to a second securing side of the first working device, said first and second securing sides facing one another in the longitudinal direction of the gap. A diverting device, directs the covering band from the first securing side to the second securing side of the first working device, and also from the first securing side of the first working device to the second working device, where it is lifted away from the gap using a lifting device and directed past the second working device.

To provide a hand stocker with a simple structure. A hand stocker housing a hand for attaching on an actuator includes a housing board that houses the hand in a hung state and includes a hanging mechanism hanging the hand on a board surface facing the hand. The hanging mechanism includes: a hooking member that extends in a horizontal direction from the board surface to engage with a hanging portion disposed in the hand; a pressing member that prevents the hand hung on the hooking member from moving to a direction separating from the board surface; and a supporting member that restricts the hand hung on the hooking member from moving to a direction approaching the board surface. The hand is sandwiched between the pressing member and the supporting member and housed.

A system for positioning a patient before, during or after a medical procedure can include an arm assembly and a surgical drape for use with the arm assembly. The surgical drape can be configured to be placed around a surgical site where an operative procedure is to be conducted. The surgical drape includes a transparent viewing window, multiple handle covers, and an expandable opening on the top side of the surgical drape. Additionally, the surgical drape may also include adhesive components on the bottom side of the drape that may be independently removed in order to affix the drape around a surgical site.

Systems and methods for detecting contact between a link and an external object are provided. In one aspect, there is provided a robotic system, including a manipulatable link, a rigid shell configured to overlay the manipulatable link, and one or more sensors positioned between the rigid shell and the manipulatable link. The one or more sensors are configured to detect contact between the rigid shell and an external object.

A collaborative robot line management system comprises a first bracket and a second bracket. The collaborative robot line management system is operable to manage the positioning and routing of a plurality of flexible lines relative to a collaborative robot. The first bracket comprises a support portion having a plurality of apertures formed therein, and a collaborative robot mounting portion configured to interface with a first mount of a collaborative robot. The second bracket comprises a support portion having a plurality of apertures formed therein, and a collaborative robot mounting portion configured to interface with a second mount of a collaborative robot. The collaborative robot mounting portions of the first and second brackets facilitate mounting of the first and second brackets to the collaborative robot at first and second mounting locations, respectively.

A sealing member (2), for waterproof sealing of a volume, comprises a hollow, generally cylindrical body and a sealing area (5a, 5b) at the respective axial ends thereof. At least one sealing area (5a) comprises a first radially extending portion (6) and a second portion (7) extending in a reverse direction partly overlapping the first portion. The second portion (7) has a free end and is arranged for pressing towards the first portion (6), thereby forming a seal with the first portion (6).

A sealing system comprises a sealing member (2) as above, a sealing seat (9) for abutment against the sealing member (2), and a counterpart surface (11), for pressing the sealing member (2) against the sealing seat (9). The sealing seat (9) comprises an inclined surface (10).

A work tool (1) comprising the above-mentioned sealing system has at least one sealing area (5a) of the sealing member (2) pressed between a housing (4) and a chassis (3) of the work tool (1).

A modular robotic vehicle (MRV) having a modular chassis configured for a vehicle utilizing two-wheel steering, four-wheel steering, six-wheel steering, eight-wheel steering controlled by a semiautonomous system or an autonomous driving system, either system is associated with operating modes which may include a two-wheel steering mode, an all-wheel steering mode, a traverse steering mode, a park mode, or an omni-directional mode utilized for steering sideways, driving diagonally or move crab like. Accordingly, during semiautonomous control a driver of the modular robotic vehicle may utilize smart I/O devices including a smartphone, tablet like devices, or a control panel to select a preferred driving mode. The driver may communicate navigation instructions via smart I/O devices to control steering, speed and placement of the MRV in respect to the operating mode. Accordingly, GPS and a wireless network provides navigation instructions during an autonomous operation involving driving, parking, docking or connecting to another MRV.

A layer jamming driving device is proposed, which includes an enclosure made of a variable material; and layer stacked structures having a plurality of layers stacked inside the enclosure, wherein the layer stacked structures can be coupled so as to be slidable and rotatable with respect to each other.
