Self-Driving Catheter Robot Navigates the Heart for Surgery
When navigating through dark environments, rats swish their whiskers against nearby objects to figure out where they are. As the animals explore, they use this sense of touch to build maps of unfamiliar places. Cockroaches and blind crayfish use their antennae in a similar approach. Now, the go-by-feel strategy has inspired the creation of a robotic catheter capable of finding its way through the beating heart of lives pigs during a surgical procedure without the help of a surgeon’s guiding hand.
