Device having a vibration based propulsion system

A device comprising:

• a housing;
• and
• at least one vibration causing mechanism comprising at least one of:
• at least one vibratable diaphragm attached to the housing, the at least one vibratable diaphragm positioned such that each of the at least one vibratable diaphragm moves from an extended position extending away from the housing to a retracted position that is positioned closer to an interior of the housing than the extended position to drive movement of the device, and
• at least one vibration causing device positioned in the housing that moves a weight forwardly and rearwardly within the housing to vibrate the housing to drive movement of the device;
• wherein the housing has a bullet-like shape, a submarine shape or a conical shape and wherein the at least one diaphragm vibrates by moving parallel to a flow direction of a fluid or a moving surface to drive movement of the device.

A device comprising:

• a housing;
• and
• at least one vibration causing mechanism comprising at least one of:
• at least one vibratable diaphragm attached to the housing, the at least one vibratable diaphragm positioned such that each of the at least one vibratable diaphragm moves from an extended position extending away from the housing to a retracted position that is positioned closer to an interior of the housing than the extended position to drive movement of the device, and
• at least one vibration causing device positioned in the housing that moves a weight forwardly and rearwardly within the housing to vibrate the housing to drive movement of the device;
• at least one covering attached to the housing, the at least one covering that covers a portion of the housing and the at least one covering flopping during movement of the device.

A device comprising:

• a housing;
• and
• at least one vibration causing mechanism comprising at least one of:
• at least one vibratable diaphragm attached to the housing, the at least one vibratable diaphragm positioned such that each of the at least one vibratable diaphragm moves from an extended position extending away from the housing to a retracted position that is positioned closer to an interior of the housing than the extended position to drive movement of the device, and
• at least one vibration causing device positioned in the housing that moves a weight forwardly and rearwardly within the housing to vibrate the housing to drive movement of the device;
• wherein the housing has at least one collapsible section sized and configured so that cycling of the at least one collapsible section between extended and contracted positions contributes to movement of the device.

A device comprising:

• a housing having at least one collapsible section, and
• at least one power unit attached to the at least one collapsible section to cycle the at least one collapsible section between extended and collapsed positions;
• and
• the housing and the at least one collapsible section sized and configured so that cycling of the at least one collapsible section between extended and collapsed positions moves the device when the device is positioned in a fluid.
