A Guide for Developing Human-Robot Interaction Experiments in the Robotic Interactive Visualization and Experimentation Technology (RIVET) Simulation

ARL's Intelligent Systems Enterprise vision is to enable the teaming of autonomous intelligent systems with soldiers in dynamic, unstructured combat environments, as well as in non-combat military installations and base operations. To accomplish this vision for interdependent soldier-robot teaming, there has been a paradigm shift in robotic research conducted by ARL from the current instantiation of fielded remote-controlled or teleoperated robots to systems with increased intelligence, decision-making capability, and autonomy. This type of teaming is needed for future joint, interdependent, network-enabled operations.

Gesture-Based Controls for Robots: Overview and Implications for Use by Soldiers

Afuture vision of the use of autonomous and intelligent robots in dismounted military operations is for soldiers to interact with robots as teammates, much like soldiers interact with other soldiers. Soldiers will no longer be operators in full control of every movement, as the autonomous intelligent systems will have the capability to act without continual human input. However, soldiers will need to use the information available from, or provided by, the robot. One of the critical needs to achieve this vision is the ability of soldiers and robots to communicate with each other. One way to do that is to use human gestures to instruct and command robots.

Experimental Confirmation of an Aquatic Swimming Motion Theoretically of Very Low Drag and High Efficiency

It has been established theoretically that self-propulsion of deformable bodies in ideal fluid can occur with a careful specification of the deformation mode shape. With the fluid assumed ideal, vortex shedding, rotational wake, and induced drag would not occur. The implication is that for a real fluid, provided the existence of a thin boundary layer, similarly configured bodies with the same deformation mode shape self-propel without vortex shedding, rotational wake, and induced drag. Only viscous drag effects, due to the existence of the thin boundary layer, are present and unavoidable. The motion mode in question is the little-exploited anguilliform mode exhibited in some aquatic animal swimming. The Anguilla includes the snake, eel, lamprey, and leach, among others.

How NASA Tracks the Asteroids Flying by Earth

On Wednesday, April 19, an asteroid missed Earth by 1.1 million miles – a distance closer than you might think. This week, Tech Briefs spoke with NASA’s Planetary Defense Officer about the efforts behind tracking this type of flyby.

NASA Tests Robotic Ice Tools

Since 2015, NASA's Jet Propulsion Laboratory in Pasadena, California, has been developing new technologies for use on future missions to ocean worlds. That includes a subsurface probe that could burrow through miles of ice, taking samples along the way; robotic arms that unfold to reach faraway objects; and a projectile launcher for even more distant samples. All these technologies were developed as part of the Ocean Worlds Mobility and Sensing study, a research project funded by NASA's Space Technology Mission Directorate in Washington. Each prototype focuses on obtaining samples from the surface - or below the surface - of an icy moon.

New Robotic System Finds and Destroys Explosive Threats

In combat, land mine and improvised explosive device (IED) clearance is a slow, painstaking, stressful job that physically and mentally drains soldiers and military working dogs. Technologies that seek out a variety of explosive hazards and IED components have matured in recent years to the point that semi-autonomous robots can detect, mark, and even destroy buried threats. The latest such system is called the Standoff Robotic Explosive Hazard Detection System (SREHD), and testing is currently underway at the U.S. Army Yuma Proving Ground (YPG).

Swarms of Autonomous Aerial Vehicles Test New Dogfighting Skills

Aerial dogfighting began more than a century ago in the skies over Europe with propeller-driven fighter aircraft carried aloft on wings of fabric and wood. An event held recently in southern California could mark the beginning of a new chapter in this form of aerial combat.

Heated Concrete Could Pave the Way for Ice-Free Runways

Iowa State University tested slabs of electrically conductive concrete at Des Moines International Airport. The test slabs are made up of 1 percent carbon fiber and a special mix of cement, sand, and rocks. The carbon fiber allows the concrete to conduct electricity, but there is some resistance to the moving electrons, which creates heat.

NASA Puts Dummies to the Test for Airplane Safety

Ten crash test dummies buckled into seats in a cut-out section of a regional jet fuselage will soon help NASA and the FAA develop new crashworthiness guidelines for future airplane designs. It is part of the FAA's efforts to address how to better assess the airworthiness of new transport planes that contain nonmetallic components. The test also included baggage in the cargo hold to see how the luggage interacts with the subfloor separating it from the dummies.

Report from SPIE 2017: Drones Spot Gas Leaks from the Sky

ANAHEIM, CA. During last week’s SPIE Defense + Commercial Sensing 2017 conference, panelists from industry, academia, and government demonstrated how miniaturized sensing platforms, and the unmanned aerial vehicles (UAVs) hosting them, can improve the detection of hazardous gas leakage.
