Abstract:
Methods and systems for providing landmarks to facilitate robot localization and visual odometry are provided herein. At least one area of a physical environment in which a robotic device resides may be determined to include surfaces that lack sufficient discernable features to determine a location of the at least one area. Instructions may responsively be provided to the robotic device for the robotic device to provide a material in respective patterns onto one or more surfaces of the at least one area. Instructions can responsively be provided for the robotic device to provide the material in respective textures as well. The respective patterns or textures may include sufficient discernable features to determine a location of the at least one area, and the material may remain on the one or more surfaces for a predetermined period of time.
Abstract:
An example method includes receiving, by a mobile robotic device, power from a battery of a first battery pack in order to operate within an environment. The method further includes establishing a first data channel between the mobile robotic device and the first battery pack. The method also includes using the first data channel to transfer sensor data acquired by the mobile robotic device during operation to a local data storage component of the first battery pack. The method additionally includes navigating, by the mobile robotic device, to a battery exchange station to transfer the first battery pack containing the battery and the local data storage component with the sensor data to the battery exchange station. The method further includes after transferring the first battery pack to the battery exchange station, receiving a second battery pack from the battery exchange station to continue operation within the environment.
Abstract:
Methods and systems for determining depth information using a combination of stereo and structured-light processing are provided. An example method involves receiving a plurality of images captured with at least two optical sensors, and determining a first depth estimate for at least one surface based on corresponding features between a first image and a second image. Further, the method involves causing a texture projector to project a known texture pattern, and determining, based on the first depth estimate, at least one region of at least one image of the plurality of images within which to search for a particular portion of the known texture pattern. And the method involves determining points corresponding to the particular portion of the known texture pattern within the at least one region, and determining a second depth estimate for the at least one surface based on the determined points corresponding to the known texture pattern.

Abstract:
Example systems and methods may be used to determine a trajectory for moving an object using a robotic device. One example method includes determining a plurality of possible trajectories for moving an object with an end effector of a robotic manipulator based on a plurality of possible object measurements. The method may further include causing the robotic manipulator to pick up the object with the end effector. After causing the robotic manipulator to pick up the object with the end effector, the method may also include receiving sensor data from one or more sensors indicative of one or more measurements of the object. Based on the received sensor data, the method may additionally include selecting a trajectory for moving the object from the plurality of possible trajectories. The method may further include causing the robotic manipulator to move the object through the selected trajectory.
