A robot satellite with dual-manipulators is one of the choices to operate payload in orbit, for example, to capture or deorbit damaged satellites. We have constructed a ground experiment simulator system including two 7-degree-of-freedom (DOF) manipulators as a chaser satellite model and floating testbeds on a flat floor as target satellite models. This system is a tele-operation ground experim...

A small floating platform designed for an unmanned short-range defense system is proposed. The structures of the proposed and weapon are detailed described. investigated via virtual prototype technology in aspects motion under sea waves up to Beaufort wind Douglas (wind-sea) scale 5. equations established according ship theory, movement different wind-sea scales simulated analysed multi-body fl...

We consider the coupled system modeling the interaction of time-harmonic progressive water-waves with an array of three-dimensional freely floating obstacles in a two-layer fluid. Presenting a variational and operator formulation for the problem and a condition guaranteeing the existence of trapped waves, we give a number of examples of floating structures supporting trapped waves. We also stud...

In this paper, we performed a comparative evaluation to show the effectiveness of two interface tools, one a floating text-based menu (Floating-Menu) and the other a more interactive iconic tool (Interactive-Icon). We evaluated the use and human performance of both tools within one highly interactive visual analytics system. During task performance we tracked completion times, task errors, and ...
