Abstract: An automated order fulfillment system and mobile robot are disclosed, where the mobile robot includes a compliant drive for moving between levels of a multilevel storage structure.

Abstract: An automated order fulfillment system and mobile robot are disclosed, where the mobile robot includes a compliant drive for moving between levels of a multilevel storage structure. In one example, the compliant drive comprises a drive shaft having splines configured to provide rotational play that prevents jamming of a vertical drive gear on the end of the shaft with a rack in a vertical track.

Abstract: A remote station and method for rendering a ground plane over video feed are provided. The remote station comprises a processor, a communication interface for communicating with an unmanned vehicle (UV), and a non-transitory memory device storing a communications module. The communications module comprises machine-readable instructions that, when executed by the processor, causes the processor to render a ground plane over video feed. The method comprises receiving a video feed from a camera on a UV, receiving from the UV telemetry information of the camera, receiving from the camera a zoom factor of the camera, calculating a horizon of the camera at a UV controller of the UV, and rendering the horizon as an overlay image on the video feed at a display of the UV controller.

Abstract: Optoelectronic devices are produced as integrated chips which include elements to control optical signals and electronic elements to control the optical elements. An integrated chip includes optical wave guides with tapered ends to facilitate exit and entry of optical signals. The tapered ends are produced by photo-electrolytic etch using illumination of graded intensity, e.g. the penumbra of a shadow.
