Abstract: A water flow deflection device attached to a side of a watercraft to enhance the watercraft's wake. The device having a narrow, elongated base with two ends and a base width, the base aligned along the side of the watercraft when the device is attached to the watercraft. A deflector attached to the base between the two ends and having a face spanning between a leading end and an opposing end, the leading end extending outwardly from the base. The deflector face having a surface area configured to deflect water and a deflector width greater than the base width. The base removably attachable to the watercraft by a plurality of suction cup assemblies, wherein a greater number of suction cup assemblies located between the first end and the leading end of the deflector than between the second end and the leading end of the deflector.

Abstract: A robotic vehicle is disclosed, which is characterized by high mobility, adaptability, and the capability of being remotely controlled in hazardous environments. The robotic vehicle includes a chassis having front and rear ends and supported on right and left driven tracks. Right and left elongated flippers are disposed on corresponding sides of the chassis and operable to pivot. A linkage connects a payload deck, configured to support a removable functional payload, to the chassis. The linkage has a first end rotatably connected to the chassis at a first pivot, and a second end rotatably connected to the deck at a second pivot. Both of the first and second pivots include independently controllable pivot drivers operable to rotatably position their corresponding pivots to control both fore-aft position and pitch orientation of the payload deck with respect to the chassis.
