Abstract: An unmanned system performs inspection, identification and/or neutralization of underwater objects. An unmanned vehicle that operates at a water's surface stows underwater crawling and/or swimming vehicles that can operate underneath a water's surface. A winch associated with each robotic vehicle is mounted on the unmanned vehicle. An electro-mechanical tether electrically and mechanically couples a corresponding robotic vehicle to the unmanned vehicle, and is mechanically coupled to a corresponding winch for control of the paying out and reeling in thereof.

Abstract: A tactile sensor comprises a sensing bladder in pneumatic communication with a first diaphragm side of a pneumatic diaphragm via a first fluid; the pneumatic diaphragm being actuatable by a displacement of the first fluid within the sensing bladder; the pneumatic diaphragm further comprising a second diaphragm side in fluid isolation from the first diaphragm side; the second diaphragm side being pneumatically biased against the first diaphragm side, and the second diaphragm side and the first diaphragm side of the pneumatic diaphragm each being in pneumatic communication with an external environment.
