US researchers working on a snake-
like robot have tested pairing it
with a search-and-rescue dog.
The engineers sent two dogs fitted
with harnesses containing the robot
into a simulated collapsed building.
The dogs then released the
equipment, allowing the robot to
wriggle free.
The researchers hope the technology
will one day be used to locate people
trapped in places inaccessible to dogs.
They are working to make the robot
faster over rubble and other debris.
A video of the experiment has been
posted online by Carnegie Mellon
University's biorobotics lab.
