To save lives, search and rescue robots crawling through the rubble of a collapsed building or surveying a chemical spill area must be capable of beaming back clear, easily interpretable images of what they "see" to operators and emergency planners, working away from the immediate disaster site.

A new initiative, bringing together nine research groups from seven countries, including teams of robotics and brain researchers from Europe, the USA and Israel, has recently been set up with the aim of imitating nature.

National Institute of Standards and Technology (NIST) engineers are organizing the fourth in a series of Response Robot Evaluation Exercises for urban search and rescue (US&R) responders to be held on June 18-22, 2007, at Texas A&M's "Disaster City" training facility in College Station, Texas.
