Abstract: A charging interface for a robot includes a support frame and a charging port. The support frame can have an opening extending therethrough. The charging port can be movably coupled to the support frame and have a first portion extending at least partially through the opening. An outer surface of the first portion is spaced from the opening by a gap. The charging port can be movable relative to the support frame between a nested position where the charging port is centered and aligned within the opening and fixed relative to the support frame, and a floating position where the charging port is free to translate and rotate relative to the support frame. The charging port can be biased toward the nested position.

Abstract: A charging interface for a robot includes a housing comprising a plurality of recesses, one or more charge contact members, and one or more data contact members. The charge contact members can be at least partially disposed within on or more of the plurality of recesses. Each charge contact member can include an electrical charge pin extending through an opening of a surface of the charge contact member. The data contact members can be at least partially disposed within one or more of the plurality of recesses. Each data contact member can include an electrical data pin extending through an opening of a surface of the data contact member. The charge contact member and the data contact members can be moveably coupled to the housing.

Abstract: A system for removably coupling a battery assembly to a robot or charging system is provided herein. The system can include a cradle body, one or more connectors, and one or more charging interfaces. The cradle body can removably couple to and support a battery of varying shapes and sizes. The cradle body can wrap around at least a portion of the battery. The one or more connectors can be attached to the cradle body to releasably engage corresponding connectors of a robot when the battery assembly is coupled to the robot. The one or more charging interfaces can be attached to the cradle body via which power is provided to the battery to charge the battery.

Abstract: In example implementations, a powder level sensor is provided. The powder level sensor includes a capacitive sensor, a processor, and a cleaning mechanism. The processor is communicatively coupled to the capacitive sensor. The processor interprets a measurement of the capacitive sensor to detect a layer of residual build material on a surface of the powder level sensor. The cleaning mechanism may be communicatively coupled to the processor. The processor activates the cleaning mechanism to remove the layer of residual build material on the surface of the powder level sensor.

Abstract: Examples of a mounting device and method are disclosed herein. An example of the mounting device includes a carriage to hold a printhead assembly and an interconnect assembly to supply printing composition to the printhead assembly. The mounting device also includes a first latching assembly having an engaged condition to lock the interconnect assembly to a manifold of the printhead assembly and a disengaged condition to unlock the interconnect assembly from the manifold of the printhead assembly. The mounting device additionally includes a second latching assembly having an engaged condition to lock the printhead assembly to the carriage and a disengaged condition to unlock the printhead assembly from the carriage. In this example of the mounting device, the second latching assembly cannot be moved from the engaged condition to the disengaged condition unless the fast latching assembly is in the disengaged condition.

Abstract: An apparatus in an example comprises a sheet holder, a separator surface, a feed head, and one or more arms. The sheet holder supports one or more sheets of media. The separator surface receives a leading edge of a sheet of the one or more sheets of media. The feed head is selectively positionable against a face of the sheet. The one or more arms extend toward an intermediate location of the separator surface to constrain the sheet from movement away from the separator surface.

Abstract: A media size sensing system includes independently moveable length and width edge guides, in a media tray, for positioning against orthogonal edges of media sheets. A linearly sliding sensor device is provided, and a single linkage connects the length and width edge guides to the sensor device, the single linkage providing a unique position indication that is a function of both length and width for a range of media sheet sizes.
