<p num="1"><br/><br/> This invention is directed to a novel amphibious surface vehicle <br/>(10) having a hull like chassis (11) with a plurality of rotary engagement <br/>devices <br/>(14) adapted for travel over various surface terrains and fluidic substances <br/>(17). <br/>Each engagement device includes rotors (16) having a multi-lobular periphery <br/>that provides improved tractive and propulsive attributes. The rotors are<br/><br/> coupled through a driven eccentric hub (30) and phased by a non-circular <br/>internal gear pair (27, 37) so as to provide synchronized linear motion upon a <br/><br/>weight bearing surface (15). The rotors with an overlapping contact ratio <br/>which <br/>produces increased traction and bearing area translating to improved overall <br/>performance upon a planar surfaces (15). This overlapping action becomes more <br/>paddle like when surface penetration occurs or by adjusting lever (19) <br/>aggressively changing the phasing incidence of the rotors (16), which is <br/>conducive to fluidic propulsion on water or other low shear strength <br/>substances <br/>(17).<br/><br/>
