Autonomous Underwater Munitions and Explosives of Concern Detection System

The objective of Environmental Security Technology Certification Program (ESTCP) Project MR-201002, Autonomous Underwater Vehicle (AUV) Munitions and Explosives of Concern (MEC) Detection System, was to integrate an untethered and unmanned underwater vehicle with a total field magnetometer for underwater munitions detection and upgrade magnetic noise compensation software to reduce interference from electrical and dynamic influences such as vehicle heading, pitch and roll.

Power-Line UAV Modeling and Simulation

The Army Research Laboratory Power-Line Unmanned Aerial Vehicle (UAV) Modeling and Simulation (ARL-PLUMS) Software Tool allows a user to model, compute, and analyze the quasistatic electric and magnetic fields around alternating current (AC) power lines. ARL-PLUMS comes with an interactive graphical user interface (GUI), which accesses a compute engine to calculate these fields around these lines due to various ground and line geometries and load conditions. ARLPLUMS allows the user to rapidly define all significant model parameters and compute the electric and magnetic fields along a UAV path or in a cutting plane. In addition, a set of false-color plots can be created to show the time-varying nature of the fields as a movie. ARL-PLUMS also comes with an application programming interface (API) for accessing some of these features from MATLAB without using the GUI.

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.

Using SWaP-C Reductions to Improve UAS/UGV Mission Capabilities

The defense and aerospace market continues to push for reductions in size, weight, power, and cost (SWaP-C) to support advanced sensor/vetronics payloads onboard unmanned platforms. Groundbreaking SWaP-C reduction for processor and network switch systems are enabling UAS (unmanned aircraft system) and UGV (unmanned ground vehicle) platforms to expand their mission capabilities. Several technologies are driving this small form factor revolution, including tightly integrated system- on-chips (SoCs), semiconductor packaging advancements (i.e. smaller nanometer dies, lower voltage chips), and micro-miniature rugged connectors.

Designing Rugged Computing Platforms for UGVs

While the military’s proliferation of unmanned aircraft, or drones, continues to grab the headlines, the deployment of unmanned ground vehicles (UGV) is also anticipated to expand based on their role in helping military operations become more agile, responsive and safe. Intensifying mission requirements for UGVs called for in Future Combat Systems (FCS) depends on their ability to cost-effectively contribute to significant increases in intelligence through reconnaissance, surveillance, and target acquisition, coupled with the ability to handle high-risk or labor intensive tasks and the efficient transporting of personnel and materials.

Bi-manual Dexterous Manipulation for Maritime Explosive Ordnance Disposal

Since 2001, there has been a proliferation of robots within the U.S. military to assist with Explosive Ordnance Disposal (EOD) missions. Ground robotics systems are able to detect and dispose of Improvised Explosive Devices (IEDs) with the help of robotic manipulator arms.

Applying UUV Advances to Safeguard Harbors and Littoral Waters

Advances in unmanned underwater vehicles (UUVs) are providing government agencies and commercial organizations with new capabilities across a variety of mission requirements. However, many underwater vehicles only address specific criteria or support well-defined (and limited) niches. As an example, the Naval Sea Systems Command’s (NAVSEA) Littoral Battlespace Sensing (LBS) system includes the LBS-G long-endurance glider to collect oceanographic data, but also needs the LBS-AUV for military applications.
