摘要： An amphibious robot is provided. An aspect of the robot includes an elongated flexible body, actuators in the flexible body and spaced apart along a length of the flexible body. The actuators are configured to move the flexible body in a serpentine or concertina motion on land and in water. An additional aspect includes a camera coupled adjacent to an end of the flexible body, at least one sensor coupled to the flexible body, and a buoyancy controller located in the flexible body. Another aspect includes a power source coupled to the flexible body and configured to power the actuators, the camera, the sensors, and the buoyancy controller. Yet another aspect employs an electric controller to control the actuators and receive data from the sensors.

摘要： The present disclosure is directed towards a power distribution system for a marine vessel. The power distribution system comprises auxiliary, first and second buses and first and second propulsors for propelling the marine vessel. A first power generation system is electrically connected to the first bus and operably connected to the first propulsor. A second power generation system is electrically connected to the second bus and operably connected to the second propulsor. The first and second buses are electrically connected to the auxiliary bus such that electrical power is transferable between the first and second power generation systems for driving the first and/or second propulsors.

摘要： A floating vessel with gearless pod propulsor and counter rotating propellers is secured to a hull, each pod having a lead propeller and a trailing propeller, each propeller connected to a shaft connected to either a stator and rotor or a hydraulic motor. A lead propeller turns in a first direction and a trailing propeller turns in an opposite direction simultaneously, generating thrust for the floating vessel along a thrust vector using the counter rotation of the trailing propeller to recover swirling energy from the lead propeller improving propulsive efficiency of the floating vessel. The pod is positioned below a water line of the floating vessel providing propulsion for the floating vessel without gears.
