Abstract: An end effector for printing ink on a surface is disclosed. The end effector comprises a primary block comprises a primary-block body. A plurality of primary-printing modules are coupled to the primary-block body and translationally moveable, via a corresponding first actuator. Each one of the primary-printing modules includes at least one printhead which is adjustable, relative to the primary-block body. The printhead may be adjusted by at least one of a second actuator, configured to rotate the printhead about a first axis, or a third actuator, configured to rotate the printhead about a second axis. In some examples, a fourth actuator is configured to rotate at least one printhead, relative to at least one other printhead, about a third axis. Additionally, at least one trailing block can be coupled to the primary block so that the at least one trailing block is movable relative to the primary block.

Abstract: An end effector and associated systems and methods for printing ink on a surface is disclosed. The end effector comprises a main block including a back plate. The end effector also includes a plurality of slice assemblies slidably coupled to the back plate. Each one of the plurality of slice assemblies includes a printhead and a y-actuator. The y-actuator is selectively operable to extend and retract the printhead, parallel to a y-axis in first directions, and relative to the back plate. The end effector further includes a plurality of z-actuators coupled to the back plate. Each one of the plurality of z-actuators is selectively operable to extend and retract a corresponding one of the plurality of slice assemblies, parallel to a z-axis in second directions, which is perpendicular to the y-axis and relative to the back plate.

Abstract: A surface marking apparatus comprises a body member (3) having a first face (9) for engaging a surface of an object to be marked and a second face (17), arranged substantially at right angles to the first face (9), for engaging an edge of the object to be marked. Surface marking means (11) is provided, the marking means (11) being slidably mounted relative to the first face (9) of the body member (3). Means for securing the marking means (11) in a selected position relative to the first face (9) of the body member (3) is also provided.
