Caterpillar robot ‘treats hearts’

The HeartLander robot (Nicholas Patronik,  Carnegie Mellon University)A robotic caterpillar has been designed which can crawl across the surface of the heart to deliver treatment.

New Scientist reports a prototype of the HeartLander device, created by US researchers, has been tested on pigs.

The tiny robot, just a few centimetres long, can move at up to 18 centimetres per minute, controlled by “push and pull” wires from outside the body.

The British Heart Foundation said the “caterpillar” could one day be useful, but much more research was needed.
