  • System and method for probabilistic multi-robot SLAM
    Patent number: 11347238
    Abstract: A robot performs simultaneous localization and mapping (SLAM) using a particle filter to process sensor measurements of movements of the robot in an environment and occupied locations in the environment to produce a set of particles. Each particle includes a map of the environment and a pose of the robot in the environment to represent a probability that the environment has the map oriented with respect to the pose of the robot. The robot receives a set of particles of a neighboring robot and, in response to receiving the set of particles of the neighboring robot, updates maps of probabilistically sampled particles of the robot with maps of probabilistically sampled particles of the neighboring robot. The update includes merging a map of the sampled particle of the robot with a map of the sampled particle of the neighboring robot roto-translated based on a relative pose between the robots.
