    Abstract: A method and system for navigation of a robot along a goal path and avoiding obstacles. The method includes receiving goal pose for one or more robots and determining a goal path for a first robot while avoiding moving and fixed obstacles of a received obstacle map. A first objective function is evaluated to select a preferred velocity from a generated set of candidate velocities, the selecting based on one or more weighted cost functions. A set of velocity obstacles created based on the poses of the one or more robots and the preferred velocity is used in evaluating a second objective function to determine the motion of the robot in the next time cycle. Creating the set of velocity objects includes converting the preferred velocity from a non-holonomic to a holonomic velocity.

    Abstract: An electrical charging station for charging an autonomous robot with first and second cameras used for docking the autonomous robot with the electrical charging station. There is a front side cover with a surface, the front side cover including a first charging member configured to receive a second charging member on the autonomous robot when the autonomous robot is docked with the charging station for charging. There is a first fiducial surface including a first fiducial marker affixed to the first surface. The first fiducial surface defines a plane disposed at a first non-zero angle relative to a plane defined by the surface of the front side cover. There is a second fiducial surface including a second fiducial marker affixed to the second surface. The second fiducial surface defines a plane disposed at a second non-zero angle relative to the plane defined by the surface of the front side cover.

    Abstract: A docking station for charging a robot including an electrical charger assembly affixed to the charger docking station and configured to mate with an electrical charging port on the robot when the robot is docked at the docking station for charging. There is at least one compliant member interconnecting the electrical charger assembly to a portion of the docking station to allow movement of the electrical charger assembly relative to the electrical charging port on the robot when the robot is mating with the docking station.

    Abstract: A mobile robot having a removable wheel-drive assembly, comprising a mobile base having a chassis and a first wheel well member with a flange. There is a removable wheel drive assembly with a mounting bracket. There is a motor drive unit disposed on the mounting bracket and a wheel/tire connected to the motor drive unit via an axle. There is a second wheel well member on the mounting bracket and positioned between the motor drive unit and the wheel. The second wheel well member includes a central section having an aperture through which the axle passes and a top surface. The top surface of the central section of the second wheel well member engages with the flange of the first wheel well member of the mobile base.
