Abstract: An explosive disruptor includes a first jacket having joined inflatable members. The inflatable members are adapted to be filled with a gas. A second jacket is surrounded by and coupled to the first jacket. The second jacket has an outer radial wall, an inner radial wall spaced apart from the outer radial wall, and two end walls coupled to opposing axial ends of the outer radial wall and the inner radial wall. A first volumetric region is defined between the outer radial wall, the inner radial wall, and the two end walls. A second volumetric region is defined by the inner radial wall. The first volumetric region is sealed and adapted to be filled with a liquid. An explosive material is disposed in the second volumetric region. A blasting cap is in contact with the explosive material.

Abstract: An apparatus for lifting a buried explosive device includes a T-shaped base including a flange member and a web member. The web member has one end fixed at a right angle to the midpoint of the flange member. A vertical upright member is fixed at one end to the midpoint of the flange member. A diagonal member is fixed at one end to the other end of the vertical upright member and fixed at another end to a second end of the web member that is distal the flange member. The vertical upright member is at least twice a length of the web member. The flange member, the web member, the vertical upright member and the diagonal member are L-channel members made of carbon fiber.

Abstract: A modular disruptor cannon includes three open-ended tubular structures. A first tubular housing defines a first interior region longitudinally aligned with a second interior region. The first tubular housing has external-surface threads at a first end thereof adjacent to the second interior region. A tubular insert is fitted in the second interior region. A second tubular housing defines a cap longitudinally aligned with a barrel. The barrel has an inside diameter equal to the inside diameter of the tubular insert. The cap has internal-surface threads for mating with the external-surface threads of the first tubular housing where the barrel is longitudinally aligned with the tubular insert.

Abstract: A fluid-jet-generating container for a flowable material includes a one-piece open-ended body having eight sides and eight corners. Each of the eight corners is defined by a V-notch such that the open-ended body may define a collapsed state when the eight sides are disposed in two parallel planes, and may define a configured state with the eight sides arranged to define an open-ended U-shaped trough. End caps are sealed to the opposing ends of the open-ended body in its configured state.

Abstract: The remote excavator tool fastens to a robotic arm on a remotely controlled robotic platform that includes a track drive. The tool uses high speed tilling elements rotating at about 1500 rpm to dig, efficiently, a trench using a small amount of power. The tilling elements are hardened steel, rotating counterclockwise to a conventional tiller. The tilling elements are symmetrically mounted on a polygonal shaft, and include right and left multiple couples of paired facing disks with staggered curved tines, where the tines are thick and have tapered hardened edges. Round brushes are interspaced between couples. The loosen soil is pushed forward and to the sides to help protect the robotic platform and maintain control of the tool especially as the rate of the excavation partially depends on the characteristics of the material being excavated.
