  • Publication number: 20230283925
    Abstract: A method for training an object detection system includes estimating a location of a first object in an environment based on a density cluster map generated from a plurality of images of the environment. The method also includes generating one or more negative training samples of the first object in the environment based on the plurality of images, each of the one or more negative training samples corresponding to a second object at a location in the environment that is different than the estimated location of the first object. The method further includes generating positive training samples from a set of images of the first object. The method also includes training the object detection system to detect the first object based on the positive training samples and the negative training sample.

  • Publication number: 20230154015
    Abstract: A method for performing a task by a robotic device includes mapping a group of task image pixel descriptors associated with a first group of pixels in a task image of a task environment to a group of teaching image pixel descriptors associated with a second group of pixels in a teaching image based on positioning the robotic device within the task environment. The method also includes determining a relative transform between the task image and the teaching image based on mapping the plurality of task image pixel descriptors. The relative transform indicates a change in one or more of points of 3D space between the task image and the teaching image. The method also includes performing the task associated with the set of parameterized behaviors based on updating one or more parameters of a set of parameterized behaviors associated with the teaching image based on determining the relative transform.

  • Patent number: 11586861
    Abstract: A system includes a memory module configured to store image data captured by a camera and an electronic controller communicatively coupled to the memory module. The electronic controller is configured to receive image data captured by the camera, implement a neural network trained to predict a drivable portion in the image data of an environment. The neural network predicts the drivable portion in the image data of the environment. The electronic controller is configured to implement a support vector machine. The support vector machine determines whether the predicted drivable portion of the environment output by the neural network is classified as drivable based on a hyperplane of the support vector machine and output an indication of the drivable portion of the environment.

  • Publication number: 20220410757
    Abstract: A multi-charger, serially operated electrical vehicle (EV) charging system, contains a Power Control System (PCS) providing DC power. A plurality of EV chargers is serially power-connected to each other, wherein the first EV charger is connected to the PCS. There are sets of relays in at least the first EV charger, wherein a first set of the set of relays, when activated, is configured to supply power to a respective charging cable of the EV charger, and a second set of the set of relays, when activated, is configured to supply power to a next-serially connected EV charger. The sets of relays contain auxiliary contacts providing relay status information. A hardware logic prevents the first and second sets of relays from simultaneously being activated, allowing only one EV charger of the plurality of EV chargers to charge at a time.
