Abstract: A method, system, and wheeled base for navigating a robot for docking with a charger docking station. The robot receives an initial pose associated with a robot charger docking station and a mating pose associated with the robot charger docking station. The robot first navigates from a location to an initial pose using scan matching to a first map. The robot performs a second navigation from the initial pose to the mating pose using scan matching to a second map, thereby causing an electrical charging port of the robot to mate with an electrical charging assembly of the robot charger docking station. Localization during charger docking may use a higher resolution map than when navigating to the docking station. Localizing against the robot charger docking station may be performed on a higher resolution map of the docking station alone.

Abstract: A method and system for docking a robot with a charger docking station, including receiving an initial pose and receiving a mating pose associated with the robot charger docking station, performing a first navigation from a location to the initial pose, and performing a second navigation of the robot from the initial pose to the mating pose. The second navigation may proceed substantially along an arc path from the initial pose to the mating pose, thereby, upon arriving at the mating pose, an electrical charging port of the robot mates with an electrical charging assembly. The arc path may be associated with a section of a unique circle having a radius and a center equidistant from the initial pose and the mating pose. Controlling for error may include a proportional control and/or weighted control or switching between the controls to maintain an error below a threshold.

Abstract: A high voltage circuit breaker comprises a vacuum interrupter module, a drive module, and an actuator. The vacuum interrupter module has a vacuum interrupter housing and a pair of electrical contacts disposed in the vacuum interrupter housing. At least one of the pair of electrical contacts is movable relative to the other of the pair of electrical contacts to engage and disengage the electrical contacts from one another for switching a high voltage on and off. The drive module has a drive module housing and a drive member coupled with the at least one movable electrical contact. A central part of the drive member is disposed in the drive module housing and insulated from an ambient air. The actuator is coupled to the drive member and moves the pair of electrical contacts relative to one another.

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 method for navigating a robot from a current pose to a goal pose. A map represents obstacles and free space within an area for robot navigation. A matching map pyramid and an exclusion map pyramid are constructed based on the map and decimations from a highest resolution to successively lower resolutions of the map pyramids. Current pose for navigating from a current location to a goal pose along a goal path includes determining a search area and creating a search heap. Scoring of search tasks on the search heap determines a best candidate pose at a highest resolution matching map, or expands the search heap with search tasks at the next higher resolution matching map. Expanding the search heap at the next higher resolution matching map avoids search tasks that would localize the robot in an exclusion zone.

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: A bottle jack may be manufactured differently or converted (retro-fitted) by replacing a conventional shaft in a main lift piston to be inserted and removed, at will, without tools. The threads in the main lift piston may remain or be removed. A yoke or other head is fitted to provide registration, horizontal restraint, or both against a lifted object, component, or surface to prevent sliding off the head in use. In a smooth-walled-shaft embodiment, a set of risers (spacers, adjusters, trims, or shims) provide an extension height of the shaft, elevating the head with respect to the piston prior to beginning to lift the hydraulic piston.

Abstract: A bushing assembly for a reciprocating device is provided. The bushing assembly includes a hollow bushing housing, a collet guide member, and an adjuster mechanism. The hollow bushing housing has a substantially cylindrical shape and an angled inner sidewall. The collet guide member is disposed radially inward from and contacts the angled inner sidewall of the hollow bushing housing. The adjuster mechanism contacts a lower surface of the collet guide member and urges the collet guide member along the angled inner sidewall of the hollow bushing housing.

Abstract: An initiator including a housing adapted to be received in an igniter or rocket motor, at least one charge at a distal end of the housing, an electro-explosive device behind the charge for detonating the charge when subject to a voltage HV, and a pressure bulkhead behind the electro-explosive device. An electronic subsystem in the housing is connected to the electro-explosive device through the bulkhead and includes a lead for providing the voltage HV to the electro-explosive device to initiate it, and a switch in the lead which does not conduct if errant voltages are present on the lead to prevent initiation of the electro-explosive device until the correct voltage HV is present.
