  • Patent number: 11185988
    Abstract: Provided are a computer program product, moveable robot block, and method for a moveable robot block deployed to form a barrier and sense environmental conditions. A command is received to couple to a location in a coordinate system comprising the barrier formed of a plurality of moveable robot blocks. Movement motors are controlled to cause the moveable robot block to move to the location in the coordinate system to couple to the barrier according to the command. An environmental sensor senses an environmental condition related to water sensed external to the moveable robot block when the moveable robot block is coupled to the barrier. The environmental condition is transmitted to the assembly management system over the network.

  • Patent number: 11148284
    Abstract: Provided are a computer program product, system, and method for controlling moveable robot blocks to dynamically form a barrier. A barrier plan is generated indicating a placement of moveable robot blocks at locations in a coordinate system to form a barrier in a geographical area, wherein the coordinates system indicates locations for the moveable robot blocks to form the barrier. Commands are transmitted to the moveable robot blocks deployed in the geographical area where the barrier is to be formed to cause the moveable robot blocks to move to the locations in the coordinate system in the barrier plan to form the barrier.

  • Patent number: 11073398
    Abstract: Described herein are techniques for generating and utilizing drivability maps. The techniques including a method comprising receiving a set of vehicle performance records including a first vehicle performance record comprising a vehicle location, a vehicle configuration, and traction control system information. The method further includes determining, from the set of vehicle performance records, a respective Coefficient of Friction (CoF) value for respective road segments including a first CoF value for a first road segment. The method further includes determining, from the set of vehicle performance records and the respective CoF values, a first CoF threshold for a first vehicle configuration. The method further includes generating a drivability map for the first vehicle configuration indicating different levels of drivability for different road segments based on the respective CoF values for respective road segments and the first CoF threshold for the first vehicle configuration.
