Researchers at Tufts University have developed robots from stem cells of frogs. These robots are named Xenobots and they can self-heal after damage, record memories and work together in groups.

These biological robots can record information about their surroundings and move using cilia -- minute hairlike particles present on their surface.

Researchers say the soft-body living machines can have several applications in biomedicine and the environment.

So far robots have been made from artificial materials, but making self-organised living machines has remained a major challenge, researchers said.
