U.S. Setting New Records
Smaller Eyes for UAVs

The Office of Naval Research has put out the word that it wants industry to develop more compact electro-optical infrared (EO-IR) focal plane array sensors for unmanned vehicles. One goal of the Image Optimization for Small Focal Plane Arrays program is to bend the cost curve for surveillance technology down in the coming years. Currently, development of large arrays for wide-area surveillance is pushing the curve upwards. In addition to the cost-control aims, the program is intended to spur the development of image processing techniques that can achieve useful results from small-format sensors.

Multi-Fuel Mini Drone Flies

Direct Drive Turbine Developments Two defense systems manufacturers have teamed up to integrate a new propulsion system into one company’s miniature drone aircraft. The drone had previously been fitted with electric propulsion, but the new, internal-combustion propulsion system will provide significantly longer flight times. The engine can operate on Jet-A (used for the maiden flight), JP-8, Diesel, or Mo-Gas.

Advanced Video for Unmanned Vehicles

Turbulence Modeling Tames Tight Turbines When the primary mission for a UAV is surveillance, intelligence-gathering, or targeting, the quality of the video feed must be excellent. But even more important is the ability to extract tactically useful information from acquired images and present it in actionable formats for the end-user. A representative of General Electric Intelligent Platforms (GE-IP) discusses these and other requirements in an interview at the Association for Unmanned Vehicle Systems International’s 2011 Unmanned Systems North America event. GE-IP has also issued a white paper on the subject (registration required).

Open Platform for Autonomous Vehicles

Turbine Transformer Tips In addition to reliable and rugged components, embedded systems supporting mission critical operations need reliable software, from the operating system on up. Green Hills Software is now offering a platform specifically for unmanned, autonomous vehicles, based on its INTEGRITY-178B real-time operating system (RTOS). In addition to other important characteristics, the RTOS meets the software safety requirements of RTCA/DO-178B Level A for safety and total reliability, and the information assurance requirements of the U.S. Government's EAL6+ Separation Kernel Protection Profile (SKPP) for absolute security.

Motor Control Case Study

Bird and Bat Science A supplier of high-reliability servo drives has issued a case study in which five of its drives were designed into a man-portable military robot. The small vehicle has the capability of expanding its two wheels into tracks as it encounters difficult terrain, and extending a “bridge” to stabilize it when the going gets particularly rough. The case study is comprehensive and illustrates the challenges involved in executing the versatile system.

Robotic Dogs of War

Taming Transport Bottlenecks It may not be biomimicry exactly, but this quadruped robot from MIT spinoff Boston Dynamics is called AlphaDog. In a project funded by the U.S. Defense Advanced Research Projects Agency (DARPA), the company developed a robot that could carry supplies for troops, negotiate uneven terrain, and follow its human partners autonomously. AlphaDog accomplishes it all, and has the ability to right itself in the unlikely event it is knocked over.

Microbes Fuel Microrobots

Ultra-capacitors Make Their Pitch The U.S. Naval Research Laboratory (NRL) has announced that it will pursue the development of compact power sources for small robotic vehicles operating in environments or locations in which human intervention is not possible. One direction the research is going is microbial fuel cell technology. However, the fuel cell technology will have to be mated with electronics and motion components drawing extremely low levels of power.

Mini UAVs Get MEMS Gunshot Detection

Driving Drivetrain Reliability Detecting gunshots has long been a technology challenge, but now a Dutch company has come up with a new approach to acoustic detection for UAVs. A MEMS vector sensor mounted on mini UAVs detects gunshots at distances up to 7 km. By calculating acoustic particle velocity, the system delivers bearing, firing source elevation, and distance via triangulation.
