Abstract: A robotic platform or “bot” having a dual track mobility system. The bot is unmanned and autonomous, or may be controlled via remote control. The dual track dual suspension-tension system has first and second tracks positioned along lateral sides of the bot and extending longitudinally over a plurality of rollers. The bot may include suspension arms coupled to groups of the rollers on the ground facing sides of the tracks for suspension and the non-ground facing side of the tracks for tension in the tracks. The bot can operate in a first orientation and a second, vertically opposite orientation and maintain suspension capabilities in either orientation. The bot may include a payload mounted in a payload bay and that is configured to rotate in at least two axes. The bot may include a symmetrical sensor assembly configured to operate according to a reference frame controlled via a control system.

Abstract: A method and system are provided for sourcing and sinking reactive power to an electric grid. The control system includes a terminal electrically coupled to a power source that originates from an electric utility grid. The terminal receives a grid alternating current having a real power component and a reactive power component. A power converter is electrically coupled to the terminal, the power converter includes an active rectifier that converts substantially all of the grid alternating current to a direct current and an energy storage device that stores energy supplied by the direct current. The active rectifier sources the reactive power component and the stored energy through the terminal to the electric utility grid. The power converter further includes an inverter that converts the direct current to a load alternating current having at least one of a load real power component and a load reactive power component.
