Snake robot teams up with rescue dog

Help

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.
