Researchers at Johns Hopkins University programmed a robot to perform minimally invasive keyhole surgery on pigs,with little help from human surgeons.

The robot performed intestinal anastomosis on four pigs, for a total of 86 stitches; stitches were placed autonomously two-thirds of the time.

The results one week after surgery were comparable to those performed by human surgeons.

The robot was controlled by custom software that senses depth and maps the changing layout inside the abdomen using images from a three-dimensional (3D) camera on the robot's arm.

Despite the trial's success, Johns Hopkins' Justin Opferman said fully autonomous surgery in humans is likely decades away.
