    Abstract: A fluid metering device may meter the flow of fluid. The device may have a main chamber and a piston configured and oriented to reciprocate within the main chamber. The piston may be configured and oriented to define a first and a second sub-chamber whose volumes vary inversely as a function of the position of the piston during its reciprocation. The fluid metering device may have a first inlet valve configured to controllably regulate the flow of fluid into the first sub- chamber, a first outlet valve configured to controllably regulate the flow of fluid out of the first sub-chamber, a second inlet valve configured to controllably regulate the flow of fluid into the second sub-chamber, and a second outlet valve configured to controllably regulate the flow of fluid out of the second sub-chamber. A valve controller may be configured to control each of the values in a manner that causes fluid to flow through the each of the sub-chambers at an average rate that substantially tracks a control signal which is delivered to the valve controller.

    Abstract: Apparatus and methods are disclosed that are useful for robotic gantry systems that are lightweight while at the same time offering rigidity or stiffness for implementation in Contour Crafting construction and material delivery techniques. The present disclosure is directed to robotic gantry system and material transport apparatus that use of very light structural members that have sufficient compressive strength, but which may otherwise be weak in the presence of bending forces, in conjunction with cables that provide stiffness against bending. Use of such cables provides needed tension while at the same time allowing the robotic gantry system to be very light compared to solid structures, e.g., those with I-beams, etc. Material delivery systems including passive articulated arms are also disclosed.
