This exercise was sponsored by the Department of Homeland Security’s Science and Technology Directorate to develop performance standards for robots for use in urban search and rescue missions.
Urban search and rescue robots assist first responders by performing such tasks as entering partially collapsed structures to search for living victims or to sniff out poisonous chemicals. NIST is developing robot standards for testing in cooperation with industry and government partners.
“It is challenging to develop the test standards as the robots are still evolving,” explained Elena Messina, acting chief of the Intelligent Systems Division, “because standards are usually set for products already in use. But it is critical for developers to be able to compare results, which is not possible without reproducible test environments. So, we have reproducible rough terrain that everyone can build in their labs, whereas you can’t reproduce a rubble pile. This way, developers in Japan can run tests, and people in Chicago can understand what the robot achieved.”
The event took place at Disaster City, Texas, a test facility run by the Texas Engineering Extension Service (TEEX). The facility offers an airstrip, lakes, train wrecks and rubble piles that can be arranged for many types of challenging tests.
Exercises included testing battery capacity by having robots perform figure eights on an undulating terrain and mobility tests in which robots ran through increasingly challenging exercises beginning with climbing steps and escalating to climbing ramps and then making it up steps with unequal gaps. A new mapping challenge introduced at this event tests how accurate a robot-generated map can be—the robot must traverse a simulated “wooded area” that has uneven terrain and PVC pipes for trees, and create a map using its sensors. Researchers came from across the globe to collect data to feed into their mapping algorithms. NIST researchers developing ultra-high-resolution three-dimensional sensors also participated.
Communications and manipulator tests were performed and discussed at the November exercise will be submitted to ASTM International as a potential rescue robot test standard.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
