Robot takes on the role of scheduling nurse in a busy hospital labor ward

We hear plenty of stories about AI being used in medicine, whether it’s discovering new drugs or helping diagnose diseases based on symptoms which may be imperceptible to even expert physicians.

One area we’ve not previously heard about machines working in, however, is in the role of “resource nurse” in a hospital. A nurse in this position in the labor and delivery ward is responsible for making decisions about the rooms patients should be assigned to, or which physician should perform a C-section. That’s work that researchers in MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) attempted to replicate recently — with a Nao robot trained to learn how these scheduling choices are made and make similar decisions on its own.

“What we were able to show is that a system with only a few dozen training examples from people performing a task very well was able to make decisions which appear to be reasonable,” Professor Julie Shah, of of the authors of the study, told Digital Trends. In the experiment, the suggestions the robot made — courtesy of its machine learning algorithm — were accepted by nurses at Boston’s Beth Israel Deaconess Medical Center 90 percent of the time.

But this isn’t about replacing human experts with machines, Professor Shah says. Instead, she says the mission of her lab is to design “human-aware AI,” referring to machines that can “better understand humans and human decision-making, so that it can collaborate with people and help make them better in their jobs.”

Essentially, it’s a philosophical continuation of the “expert system,” a type of AI which enjoyed a boom period in the 1980s — based on the dream of coding the knowledge of a select few experts and making it available to the masses, where it can be used as a training tool.

“We wanted to see if we could learn from these superstar nurses, and help make other people into superstars as well — with the machine’s help,” Professor Shah says.

While there is still work to be done before CSAIL’s tool is rolled out (including making sure that novice nurses won’t unquestioningly follow the algorithm’s suggestions) it’s yet another example of a complex real-world optimization problem that AI can help solve.

This Google robot taught itself to walk, with no help whatsoever, in two hours
Google Robot

Do you remember that scene in Walt Disney’s Bambi where the titular fawn learns to stand up and walk under its own power? It’s a charming vignette in the movie, showcasing a skill that plenty of baby animals -- from pigs to giraffe to, yes, deer -- pick up within minutes of their birth. Over the first few hours of life, these animals rapidly refine their motor skills until they have full control over their own locomotion. Humans, who learn to stand holding onto things at around seven months and who begin walking at 15 months, are hopelessly sluggish by comparison.

Guess what the latest task that robots have beaten us at? In a new study carried out by researchers at Google, engineers have taught a quadruped Minitaur robot to walk by, well, not really having to teach it much at all. Rather, they’ve used a a type of goal-oriented artificial intelligence to make a four-legged robot learn how to walk forward, backward, and turn left and right entirely on its own. It was able to successfully teach itself to do this on three different terrains, including flat ground, a soft mattress, and a doormat with crevices.

Samsung's ball-shaped robot, called Ballie.

It looks like a grapefruit. It rolls like a grapefruit. But it most certainly is not a grapefruit. It's Ballie, a new spherical robot from Samsung.

The new ball-shaped bot made its debut on the stage at Samsung’s CES event on Monday night, appearing alongside HS Kim, who leads the tech giant's consumer electronics unit.
