Robotics researchers have worked hard to realize a long-awaited vision: machines that can eliminate the need for people to work in hazardous environments. Chapter 60 is framed by the vision of disaster response: search and rescue robots carrying people from burning buildings or tunneling through collapsed rock falls to reach trapped miners. In this chapter we review tangible progress towards robots that perform routine work in places too dangerous for humans. Researchers still have many challenges ahead of them but there has been remarkable progress in some areas. Hazardous environments present special challenges for the accomplishment of desired tasks depending on the nature and magnitude of the hazards. Hazards may be present in the form of radiation, toxic contamination, falling objects or potential explosions. Technology that specialized engineering companies can develop and sell without active help from researchers marks the frontier of commercial feasibility. Just inside this border lie teleoperated robots for explosive ordnance disposal (EOD) and for underwater engineering work. Even with the typical tenfold disadvantage in manipulation performance imposed by the limits of today’s telepresence and teleoperation technology, in terms of human dexterity and speed, robots often can offer a more cost-effective solution. However, most routine applications in hazardous environments still lie far beyond the feasibility frontier. Fire fighting, remediating nuclear contamination, reactor decommissioning, tunneling, underwater engineering, underground mining and clearance of landmines and unexploded ordnance still present many unsolved problems.
UNMACA: Demining Afghanistan

Video ID : 571
This is a high-quality video made partly with the aim of seeking funds to help complete demining projects in Afghanistan.
This video has been included because researchers can see plenty of examples of realistic field conditions under which demining is being done in Afghanistan. It is essential for researchers to have an accurate appreciation of the real field conditions before considering expensive research projects.
There are plenty of opportunities to see manual mine clearance. Current-generation demining machines don't work here because of the very hard and rocky ground. There is an interesting segment showing the Bamyan site. The sentiments expressed by deminers are genuine, in my experience. I have met many similarly dedicated Afghan deminers, and they are selected for their dedication, attitude to nation-building, courage, and conscientious work ethic. They are justly proud of the work they do, and their uniforms and equipment set them apart from most other Afghans and give them a real sense of respect. Note that winter rains and summer storms wash mud over mines, encasing them in what later turns to hard, cement-like soil. It is hard physical work demanding sensitive hands, care, and attention to detail.
