  • Publication number: 20220196433
    Abstract: Implementations are directed to assigning corresponding semantic identifiers to a plurality of rows of an agricultural field, generating a local mapping of the agricultural field that includes the plurality of rows of the agricultural field, and subsequently utilizing the local mapping in performance of one or more agricultural operations. In some implementations, the local mapping can be generated based on overhead vision data that captures at least a portion of the agricultural field. In these implementations, the local mapping can be generated based on GPS data associated with the portion of the agricultural field captured in the overhead vision data. In other implementations, the local mapping can be generated based on driving data generated during an episode of locomotion of a vehicle through the agricultural field. In these implementations, the local mapping can be generated based on GPS data associated with the vehicle traversing through the agricultural field.

  • Publication number: 20200200153
    Abstract: An apparatus and method of manufacturing an apparatus that includes a rectangular frame, a first load bearing conductive support bisecting the rectangular frame lengthwise, and two artificial muscle actuators disposed on the same sides of the rectangular frame as the first load bearing conductive support on opposite sides of the first load bearing conductive support is disclosed. The apparatus includes a non-conductive platform, where the width of the frame is sufficiently wide to prevent the non-conductive platform from touching the sides of the frame when rotated about the axis of the load bearing support. The apparatus includes a device disposed in the center of the non-conductive platform. Individual actuation of the artificial muscle actuators rotates the non-conductive platform about the axis of the first load bearing conductive support.
