Methods and systems to control stacked hexapod platforms for use as tools, which function with both high accuracy and high precision are provided. In some embodiments, the methods and systems include a convergence of modern control theory, and machine learning. Furthermore, some embodiments provide control algorithms to carry out autonomous in-space assembly operations using assemblers. Some embodiments provide methods and systems which combine long-reach low precision manipulators and smaller, high-precision assembler with interchangeable tools.

Modular and reconfigurable assembler system for autonomous in-space assembly

A foiled grating is provided for use with a jet-powered personal watercraft. The grating is adapted to be secured substantially across the intake opening in the bottom of the craft's hull and includes a foil and at least two substantially parallel bars oriented longitudinally within the intake opening. The foil is supported by the bars and positioned so as to divide a section of the intake channel into upper and lower portions to direct the intake water flow for a more even flow to the craft's jet pump.
