Abstract: Methods, apparatus, systems, and computer readable media are provided for determining: 1) sensor parameters for sensors of a robot and 2) model parameters of a dynamic model of the robot. The sensor parameters and model parameters are determined based on applying, as values for known variables of a system equation of the robot, sensor readings and position values for each of a plurality of instances of a traversal of the robot along a trajectory. The system equation of the robot is a dynamic model for the robot that includes sensor models substituted for one or more corresponding variables of the dynamic model. The system equation includes unknown variables representing unknown sensor biases for the sensors of the robot and unknown model parameters of the dynamic model of the robot. Solutions to the unknown variables are generated and utilized to determine the sensor parameters and the model parameters.

Abstract: Techniques and mechanisms to form a reinforcement structure including dirt processed during drilling of a tunnel. In an embodiment, a device includes a drill head to drill an underground tunnel, where a housing of the device takes in dirt produced by such drilling. A mixer and other components of the device variously condition the dirt to produce a casing material that is subsequently provided to a compactor of the device. The compactor extrudes the casing material through a die. The extruded casing material is eliminated from the device to form a reinforcement structure at one or more sides of the tunnel. In another embodiment, a fiber optic cable is paid out from the device into the tunnel during the drilling, or is pulled into the tunnel by the device during the drilling.

Abstract: In response to a request to package item(s), embodiments determine characteristic data for the item(s), which include an indication of a volume of each item. Container(s) for packaging the item(s) is determined based at least on the volume of each item. An arrangement of the item(s) in the container(s) is determined. One or more protective structures including one or more features are configured to position the item(s) in the container(s) according to the arrangement. Relative positions are determined for a plurality of modular elements to form the one or more protective structures. Subsets of the plurality of modular elements are deposited to corresponding relative positions to form at least one of the protective structures. The item(s) are packaged in the container(s) with the one or more protective structures to position the item(s) in the container(s) in the arrangement.

Abstract: Embodiments described herein may relate to an unmanned aerial vehicle (UAV) navigating to a target in order to provide medical support. An illustrative method involves a UAV (a) determining an approximate target location associated with a target, (b) using a first navigation process to navigate the UAV to the approximate target location, where the first navigation process generates flight-control signals based on the approximate target location, (c) making a determination that the UAV is located at the approximate target location, and (d) in response to the determination that the UAV is located at the approximate target location, using a second navigation process to navigate the UAV to the target, wherein the second navigation process generates flight-control signals based on real-time localization of the target.

Abstract: A device is provided that comprises a hardware segment and an actuator to adjust a position of the segment within a range of positions. The device also comprises an encoder to rotate about an encoder axis responsive to the actuator adjusting the position. The device also comprises data storage that includes a dataset indicating offset angles between a reference configuration and a plurality of configurations of the encoder. The device also comprises a controller to cause the actuator to adjust the position to an end of the range of positions, responsively identify a range of encoder positions of the encoder that corresponds to the range of positions of the segment, modify the dataset such that the reference configuration corresponds to an end of the range of encoder positions, and determine a mapping between the offset angles indicated by the modified dataset and the range of positions of the hardware segment.
