Frog-Like Robot Will Help Surgeons

Researchers at the University of Leeds are using the feet of tree frogs as a model for a tiny robot designed to crawl inside patients' bodies during keyhole surgery.

The tiny device is one of a growing stable of bio-inspired robots being built in the University's School of Mechanical Engineering.
It is designed to move across the internal abdominal wall of a patient, allowing surgeons to see what they are doing on a real-time video feed.
