  • Publication number: 20190091865
    Abstract: Robot systems including a robot, an on-premise computing device, and a cloud services system are disclosed. An on-premise computing device includes a processor and a non-transitory memory device storing machine-readable instructions that, when executed by the processor, cause the processor to receive raw sensor data from a robot, pre-process the sensor data to remove unnecessary information from the sensor data and obtain pre-processed data, transmit the pre-processed data to a cloud services system, receive, from the cloud services system, an object type, an object pose, and an object location of an object corresponding to the pre-processed data, and transmit a signal to the robot based on at least one of the object type, the object pose, and the object location of the object.

  • Patent number: 10215858
    Abstract: Examples relating to the detection of rigid shaped objects are described herein. An example method may involve a computing system determining a first point cloud representation of an environment at a first time using a depth sensor positioned within the environment. The computing system may also determine a second point cloud representation of the environment at a second time using the depth sensor. This way, the computing system may detect a change in position of a rigid shape between a first position in the first point cloud representation and a second position in the second point cloud representation. Based on the detected change in position of the rigid shape, the computing system may determine that the rigid shape is representative of an object in the environment and store information corresponding to the object.

  • Publication number: 20180348023
    Abstract: Implementations disclosed herein may relate to sensor calibration based on environmental factors. An example method may involve a computing system receiving an indication of a current environment state of an area from environment state sensors. While the environment sensors indicate that the area is in a particular environment state, the system may receive data corresponding to an aspect of the area from a first sensor as well as data from additional sensors. Using the received data, the system may compare the data from the first sensor with a compilation of the data from the additional sensors to determine an accuracy metric that represents an accuracy of the first sensor when the first sensor operates in the area during the particular environment state. The system may repeat the process to determine accuracy metrics to calibrate sensors in the area depending on the environment state of the area.

  • Patent number: 9787908
    Abstract: Systems are provided to facilitate imaging of a person or other target in an environment by providing modulated illumination to the target and to other aspects of the environment. Modulated illumination is provided to the target such that the target receives more illumination when a camera is capturing images of the target than during other periods of time. Modulated illumination is provided to background objects or other portions of the environment of the target such that the background or other non-target elements of the environment receive less illumination when the camera is capturing images than during other periods of time. In this way, imaging of a target can be improved by increasing effective illumination of the target while decreasing glare and other effects of illumination of background objects. The illumination can be modulated at a sufficiently high frequency that the illumination appears, to the human eye, to be substantially constant.

  • Publication number: 20170148217
    Abstract: Example implementations may relate to methods and systems for detecting an event in a physical region within a physical space. Accordingly, a computing system may receive from a subscriber device an indication of a virtual region within a virtual representation of the physical space such that the virtual region corresponds to the physical region. The system may also receive from the subscriber a trigger condition associated with the virtual region, where the trigger condition corresponds to a particular physical change in the physical region. The system may also receive sensor data from sensors in the physical space and a portion of the sensor data may be associated with the physical region. Based on the sensor data, the system may detect an event in the physical region that satisfies the trigger condition and may responsively provide to the subscriber a notification that indicates that the trigger condition has been satisfied.

  • Patent number: 9417185
    Abstract: Methods and systems for controlling light arrays to determine properties of an object are described. An example method includes causing illumination of a surface of an object from multiple illumination positions using a programmable array of lights, and receiving images from an image-capture device while the surface of the object is illuminated. For example, the programmable array of lights may be modulated to cause illumination of a portion of the surface of the object from first and second illumination positions, and a first and second image of the surface of the object captured during illumination from the first and second illumination positions respectively may be received. Subsequently, a processor may determine material information for the object based on an amount of specular reflectivity for the surface of the object and reference to a database of known amounts of specular reflectivity for a plurality of materials.
