In Bangladesh rescue teams, helped by members of the community, have so far worked with small tools and their bare hands to bring out survivors. After five day the next phase will be to use heavy equipment. Having a snake robot that could provide pictures from within the building would certainly aid both phases of the operation, leading to speedier and more effective rescue operations.
It raises the question of why this technology is still a research project and not deployed?
It could be deployed and developed at the same time.
