A robotic arm includes a tool located at an end of the robotic arm that delivers a material to a surface. A hose attachment manifold is mounted to the robotic arm. The hose attachment manifold includes an array of openings that extend through a manifold body of the hose attachment manifold. Fittings are mounted to the manifold body and within the openings. A plurality of upstream hoses are mounted to the fittings at a side of the manifold body. A plurality of downstream hoses are mounted to the fittings at an opposite side of the manifold body. The plurality of downstream hoses are fluidly connected to the tool for delivering a fluid material received from the plurality of upstream hoses.

An interchangeable nozzle is provided), in particular a quick-change nozzle for applying an application agent onto a component and for fastening to a nozzle change system. The nozzle includes a nozzle body having an alignment feature for the angularly correct, mechanical alignment of the nozzle on the change system. The present disclosure also relates to an associated change system and to an associated application system.

In various embodiments, a zero-turn radius robotic base may comprise a substantially rectangular (e.g., rectangular) base portion that comprises a plurality of wheels. In various embodiments, the plurality of wheels are configured to support the robotic base adjacent a support surface (e.g., the ground, a suitable flooring surface within a building, etc.). In some embodiments, the robotic base comprises a first and second driving wheel and a plurality of stability wheels. In some embodiments, an axis of rotation of the first and the second driving wheel are collinear. In various embodiments, the plurality of stability wheels are spaces apart from the axis of rotation of the first and second driving wheels to provide stability to the robotic base.

A prosthetic heart valve includes a base and a plurality of polymeric leaflets. Each leaflet has a root portion coupled to the base, and each leaflet has an edge portion substantially opposite the root portion and movable relative to the root portion to coapt with a respective edge portion of at least one of the other leaflets of the plurality of leaflets. Each leaflet includes) at least two polymers along at least one portion of the leaflet, and each leaflet has a composition gradient of each of the at least two polymers along at least one portion of the leaflet.

An inkjet coating machine is provided to prevent the components in the paint from precipitating. The inkjet coating machine includes: a robot arm having a chuck at a front end and a nozzle head unit detachably mounted on the chuck. The nozzle head unit includes a nozzle head having a nozzle for spraying the paint, a nozzle control unit for controlling driving of the nozzle, and a head-side circulation path enabling the paint to circulate within the nozzle head. The nozzle head, the nozzle control unit and the head-side circulation path are integrally configured. The coating machine further includes a standby holding unit that holds at least one nozzle head unit in standby and a head replacement unit that replaces the nozzle head unit.

A paint robot having a sprayer that is substantially fixed in an orientation in which the spray fan is perpendicular to the wall surface may be ineffective at painting portions of a wall that are not substantially flat (e.g., flat). These portions may include one or more protrusions and/or recesses such as, for example: (1) a chair rail or other suitable piece of molding; (2) one or more window ledges and/or sills; (3) one or more exit signs; (4) one or more thermostats; (5) etc. As such, it may be desirable to incorporate an articulating spray head (e.g., a pivoting sprayer) into an automated mobile painting system in order to, for example, paint the upper and lower portions of the wall by angling the paint sprayer to paint over and/or under the various protrusions which may exist on the wall as discussed above.
