Abstract: A method for energy generation includes receiving, at a carbon negative energy generation system, input including calcium oxide and water and reacting, within a reaction chamber of the carbon negative energy generation system, the calcium oxide and water to release energy and generate calcium hydroxide. The method further includes directing, by the carbon negative energy generation system, the released energy to facilitate propulsion or onboard electricity generation and dispensing, by the carbon negative energy generation system, the calcium hydroxide into the ocean to sequester atmospheric CO2.

Abstract: Systems and methods related to roadmaps for mobile robots are provided. A computing device can determine a roadmap of an environment. The roadmap can include lanes and a designated region that is adjacent to a first lane of the plurality of lanes and suitable for robotic traversal when unoccupied. The computing device can determine a first route between first and second points in the environment that uses the first lane. The computing device can send a direction to use the first route to a first robot. The computing device can receive, from the first robot, sensor data indicative of an occupied status of the designated region. The computing device can determine a second route between the first and second points through the designated region based on the occupied status of the designated region. The computing device can send a direction to use the second route to a second robot.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for predicting locations of utility assets. One of the methods includes receiving an input image of an area in a first geographical region; generating, from the input image and using a generative adversarial network, a corresponding reference image; and generating, by an object detection model and from the reference image, an output that identifies respective locations of one or more utility assets with reference to the input image.

Abstract: A free space optical communication system transmits and receives optical signals in a colorless manner using an optical circulator. The system installs the optical circulator with a single mode (SM) fiber at port 1, a double clad (DC) fiber at port 2, and a multimode (MM) fiber at port 3. The system injects a first optical signal into a core of the SM fiber. The system then routes the first optical signal at port 1, using the optical circulator, into a SM core of the DC fiber via Port 2. Further, the system injects a second optical signal into a first cladding of the DC fiber. The system then routes the second optical signal at port 2, using the optical circulator, into the MM fiber via Port 3.

Abstract: The disclosure may provide for a communication method and system. A transmitter of the communication system may include an interleaver and a first encoder for determining parity bits. The transmitter also may include a multiplexer for joining the parity bits with the data. A second encoder may be positioned after the multiplexer for implementing an error correcting code. A receiver of the communication system may include a decoder followed by an interleaver. When errors are detected in received data at the decoder, one or more processors of the receiver may be configured to correct portions of the received data and combine the corrected portions with the received data.

Abstract: Methods, systems, and apparatus, including computer-readable media, for robot grasp learning. In some implementations, grasp data describing grasp attempts by robots is received. A set of the grasp attempts that represent unsuccessful grasp attempts is identified. Based on the set of grasp attempts representing unsuccessful grasp attempts, a grasp model based on sensor data for the unsuccessful grasp attempts. After training the grasp model, a performance level of the trained grasp model is verified based on one or more simulations of grasp attempts. In response to verifying the performance level of the trained grasp model, the trained grasp model is provided to one or more robots.

Abstract: Mitigating the reality gap through utilization of technique(s) that enable compliant robotic control and/or compliant robotic contact to be simulated effectively by a robotic simulator. The technique(s) can include, for example: (1) utilizing a compliant end effector model in simulated episodes of the robotic simulator; (2) using, during the simulated episodes, a soft constraint for a contact constraint of a simulated contact model of the robotic simulator; and/or (3) using proportional derivative (PD) control in generating joint control forces, for simulated joints of the simulated robot, during the simulated episodes. Implementations additionally or alternatively relate to determining parameter(s), for use in one or more of the techniques that enable effective simulation of compliant robotic control and/or compliant robotic contact.

Abstract: Methods, systems, and apparatus for configuring a multi-modal gas sensor array that includes multiple gas sensors. The multiple gas sensors include a first type of gas sensor and a second, different type of gas sensor. A test gas is provided to the gas sensors, where the test gas includes known analytes. Data generated by each of the gas sensors in response to the known analytes in the test gas is collected. A proper subset of gas sensors is selected to include in an optimized gas sensor array, based on the responses of the gas sensors to the known analytes in the test gas meeting a threshold response and meeting a threshold temporal response. The multi-modal gas sensor array is configured using the proper subset of gas sensors.
