Patent number: 8448904Abstract: A tool mounted on a servicer satellite for fuelling an unprepared or partially prepared client satellite. The tool includes a robotic arm mounted on the servicer satellite and a valve tool configured to be releasibly gripped by the robotic arm. The valve tool includes a housing with a support frame and a wrench mechanism mounted on the support frame. The wrench mechanism is configured for removing and replacing the first access valve cap on the first fill-drain valve and coupling a first propellant fill line to the first propellant tank optionally removing and replacing the second access valve cap on the second fill-drain valve on the second propellant tank and coupling a second propellant fill line to the second propellant tank, and actuating the valve actuation nut on the first fill-drain valve, and optionally actuating the valve actuation nut on the second fill-drain valve.Type: GrantFiled: May 14, 2012Date of Patent: May 28, 2013Assignee: MacDonald Dettwiler & Associates Inc.Inventors: Lawrence Gryniewski, Derry Crymble

Patent number: 8196870Abstract: A tool for fuelling an unprepared or partially prepared client satellite required for accessing, opening and closing a fuel fill valve on the satellite being serviced, storage and retrieval stations on a tool caddy on which the tools and various fuel fill valve caps are stored. The tool includes interchangeable socket modules, a support frame, a socket module holder mechanism, a socket drive mechanism, a clamping mechanism to secure the tool to a reaction area on the fuel fill valve and oxidizer fill valve, and a valve actuation mechanism. The interchangeable socket modules include a first module for removing and replacing the access valve cap, a second module for coupling the fuel fill line to the fuel tank, a third module for engaging the access valve cap on the oxidizer fill valve, and a fourth module for coupling the oxidizer fill line to the oxidizer tank.Type: GrantFiled: December 12, 2011Date of Patent: June 12, 2012Assignee: MacDonald Dettwiler & Associates Inc.Inventors: Lawrence Gryniewski, Derry Crymble

Patent number: 8181911Abstract: The present invention provides a method, system and apparatus for robotic refueling of satellites. The system may include a dedicated refueling satellite launched directly from either earth, or alternatively it could be launched from another larger mother spacecraft or space station in which the refueling satellite is ferried into space in the case of the larger space craft or it may be stored on the space station until needed from which it can be launched. The system includes a robotic arm, suitable tools which can be affixed to the end effector of the robotic arm required for accessing, opening and closing the fuel fill valve on the satellite being serviced, storage and retrieval stations on a tool caddy on which the tools and various fuel fill valve caps are stored. The system is under teleoperation by a remotely located operator, for example located on earth, in the mother station or in the space station.Type: GrantFiled: August 2, 2011Date of Patent: May 22, 2012Assignee: MacDonald Dettwiler & Associates Inc.Inventors: Lawrence Gryniewski, Derry Crymble, John Cameron Ower

Patent number: 6113343Abstract: A robot especially adapted for use in hazardous environments, and particularly adapted for explosives disposal, includes a wheeled platform carrying a winder mechanism which ensures that the remote control cable will not be fouled by the robot or its attachments. Coaxial with the winder mechanism is a turret mechanism that can rotate indefinitely and which carries thereon a manipulator arm section which, includes a first arm pivotable through about 110.degree. and which carries thereon a second arm which is pivotable through about 120.degree. and carries a bulkhead to which any of a plurality of end effectors can be connected by way of a quick connect and disconnect mechanism. The end effectors include a set of links having different lengths, one or two extension links, a wrist and gripper mechanism, an aiming and disruptor mechanism, and a relocatable surveillance camera.Type: GrantFiled: January 21, 1998Date of Patent: September 5, 2000Inventors: Andrew Goldenberg, Nenad Kircanski, Sheldon K.
