NIST Docket Number: 00-028US

Title: Suspended Dry-Dock Platform.

Abstract: A cable-supported platform that can precisely manipulate workers, tools/equipment and loads using position, velocity and force control modes. The platform uses six cables that attach to four support points on towers, walls or other structural supports so as to provide constraint and control of the suspended platform. The cable lengths can be independently controlled by hoist drive-mechanisms and coordinated to achieve intuitive platform movement in all six degrees-of-freedom (side-to-side, forward-and-back, up-and-down, and all three rotations about these motions: roll, pitch and yaw). The platform, consisting of servo components (i.e., hoist, amplifier, servo interface, sensory feedback), can be rapidly reconfigured to adjust to new applications. Initial applications address worker/equipment access challenges in dry dock ship and submarine repair and conversion. It can also be used for construction, high bays, and dam repair and maintenance. Various combinations of manual and automatic control can also be implemented. The hoists can be controlled manually by a multi-axis joystick, or can be automatically controlled by a computer.
