Augmented Reality (AR) is a visualization technique in which computer generated graphics are superimposed over one's view of the real world. This paper reports results of recent studies in which navigation data was superimposed into a ship pilot's field of view, including a system recently instaIIed on the US military s High Speed Catamaran Joint Venture (HSV-Xl). The system displays both navig...

Abstract In order to improve the water shooting stability of amphibious vehicle weapon, recoil motion differential equation weapon is established by analyzing force during shooting. structure valve-controlled device and optimal strategy grey predictive fuzzy control are determined, resistance characteristic curves with or without servo valve different voltages analyzed numerically. And attitude...

A crawling Remotely Operated Vehicle (ROV) has been developed for scientific activities within coastal and estuarine regions of the ocean for multiple research activities such as environmental impact assessment and integrated coastal zone management. The Modular Amphibious Research Crawler (MARC-1) ROV is designed to operate underwater and in the surfzone to a depth of five meters. The vehicle ...

Amphibious vehicles are an important unit in amphibious transportation. However, the problem of vertical load control on soft roads such as tidal flats and swamps still needs to be solved urgently. Based a new configuration wheel-track composite vehicle (W-TCAV), coupling relationship between suspension is analyzed, its 1/8 hydraulic system hydro-pneumatic suspensions established; Under conditi...

In order to reduce the additional resistance of high-speed amphibious vehicles, Flanks are designed on concave grooves. As a new drag reduction attachment, principle is analyzed and discussed in detail. this paper, HSAV model coupling tests performed based Reynolds-averaged Navier–Stokes method SST k−ω model. The accuracy numerical approach verified by series towing tests. Results show that wit...

The key motions of land and water are analyzed for a designed amphibious carrier robot. On land, based on the characteristics multi-joint crawler, robot has planned two gaits climbing steps land. kinematic models established gaits, maximum height that can climb is obtained based, Based laws dynamics, stability equation under strong transient impact to obtain conditions maintain its own when dur...

Pump-jets have a relatively high propulsion efficiency at medium speed and in heavy-load conditions for wheeled amphibious vehicles. However, the geometry of vehicles is very special due to installation requirements pump-jet, which results an obvious resistance on wheels. In order reduce vehicle, characteristics wheels are studied. Regarding pump-jet-propelled its wheel wide range firstly analy...
