Design of a Multi-Segmented Magnetic Robot for Hull Inspection

Hull, deck plate, and tank inspection for corrosion, deformation, and fractures is a necessary part of ship maintenance to ensure functional integrity and proper operation of the ship. These inspections are labor intensive, expensive, and often dangerous. A multi-segmented magnetic wheeled robot can assist the surveyors in these tasks.

A Modular Approach to Video Designation of Manipulation Targets for Mobile Manipulators

Currently fielded EOD (explosive ordnance disposal) robots are limited in terms of both mechanical ability and autonomous capabilities when compared to the current state-of-the-art in mobile robotics. To combat this problem the Joint Service EOD Program is developing the Advanced EOD Robot System (AEODRS). AEODRS consists of three system variants that vary in size: small for dismounted operations, medium for tactical operations, and large for base/infrastructure operations. Differing from past EOD UGV development efforts, these robots will be designed under a modular architecture consisting of several capability modules that are to be developed separately.

Undersea Communications Between Submarines and Unmanned Undersea Vehicles in a Command and Control Denied Environment

Nuclear powered submarines can stay submerged for days at a time and only have to come to periscope depth (PD) for communications and minor house-keeping items. Submarines are completely reliant on satellites for communications and orders from their commanders ashore. A command and control denied environment (C2DE) is an area in which communications are jammed or degraded. There is no technology currently available that allows submarines to conduct communications in a C2DE. The only method currently available is for the submarine to navigate to unaffected waters, conduct all of its communications, and then to travel back to the C2DE, wasting valuable time and possibly compromising the submarine’s mission.

UAV Can Launch Aerial Missions from Underwater

Researchers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, have developed an innovative unmanned aerial vehicle (UAV) that can stay on station beneath the water until needed, then launch into the air to perform a variety of missions. The Corrosion Resistant Aerial Covert Unmanned Nautical System — or CRACUNS — is a submersible UAV that can be launched from a fixed position underwater, or from an unmanned underwater vehicle (UUV). A team from APL’s Force Projection Sector worked with fabrication experts in the Research and Exploratory Development Department to create a new type of unmanned vehicle that can operate effectively in two very different arenas: air and water.

Robotic Falcon Captures and Retrieves Renegade Drones

Michigan Technological University is developing a drone catcher that could pursue and capture rogue drones that might threaten military installations, air traffic, sporting events — even the White House. It’s a deceptively simple system: a launcher that shoots a big net attached to a large drone by a string. The system can be autonomous, controlled by a ground-based human pilot, or a combination of the two.

Cockroach-Inspired Robots Open Doors for Military Missions

Supported by the U.S. Army Research Laboratory, University of California-Berkeley researchers have developed a small, crawling robot that mimics a cockroach's ability to squeeze through confined spaces. These spaces include rubble generated by natural disasters and explosions that first responders may not be able to access in emergencies.

Soldiers Field-Test Robotics Technology

Picture a hot summer day in Afghanistan, and a company of 25th Infantry Division soldiers preparing to move to a new area of operation. Instead of using their legs and backs, these soldiers are fortunate enough to have a small robot to help them on the battlefield. It could provide intelligence, surveillance and reconnaissance without putting soldiers in harm's way. Technology like this can be the future of the battlefield and 25th Infantry Division soldiers have been testing this theory.

Dual-Node, Short-Depth 4U Chassis

Advantech (Irvine, CA) has launched the 4U, dual-node, short-depth (350mm), industrial chassis ACP-4D00 designed for machine automation applications that require two computers in one piece of equipment. The dual node architecture allows the user to install two half-size slot SBCs in two sub-systems and integrate them in a compact 4U cage. Each ACP-4D00 node supports a PICMG 1.3 or PCI half-size CPU card with computing power up to desktop Core™ i7, 6-slot backplane with maximum 3 PCIe or PCI expansion slots (3 slots are occupied by CPU card) and 250W or 350W high-efficiency 80 Plus power supply.

Currently Advantech offers two PICMG 1.3 CPU cards— PCE-3028 (Intel® Q87), PCE-4128 (Intel® C226), and three PICMG 1.3 backplanes—PCE-3B03-00A1E, PCE-3B06-00A1E, and PCE-3B06-03A1E, for use with ACP-4D00. The system configurations support the latest Intel® 4th generation Core™ i processors, advanced PCIe Gen 3, or legacy PCI expansions.

Simulating Lightweight Vehicles Operating on Discrete Terrain

Engineers increasingly rely on simulation to augment and, in some cases, replace costly and time consuming experimental work. However, current simulation capabilities are sometimes inadequate to capture phenomena of interest.
