The first-ever self-driving robot surgeon can navigate itself through the body

A new surgical robot can guide surgeons' tools straight to the heart by itself - like a self-driving car inside the body. Researchers at Boston Children's Hospital have developed an autonomous catheter that steers itself through the body to sidestep potential navigation errors by surgeons. The first-of-its kind invention successfully reached its targets in a series of tests on pigs. For now, scientists are only looking at the autonomous tech for navigation, but some hope surgeries themselves could be done entirely by robots. But the Food and Drug Administration has warned that some robotic surgeries may be less effective than manual ones - and the public is not yet ready to trust an autonomous machine on the road, so letting one in the body might scare some.
