When my mom was in the hospital, they had a robot that carried pills from the pharmacy to the various nurses stations.
It cruised along the hallways, and avoided obstacles and people in its path.
Oh, and did I mention it sorts and counts the pills by itself?
It made a great dance partner.
This looks like it's the same one that was in my mom's hospital:

There are robots that sort pills.

But look more closely at the machines that populate her world. A hospital robot serves meals and pills to patients on complex schedules -- schedules that could lead a nurse to make mistakes. A 90-year-old man -- infirm -- uses a voice-activated robot to paint pictures and play games. Another robot sorts mail and makes phone calls for a man with muscular dystrophy.

Robot is Rx for hospital
Phred, the new pharmacist in town, helps eliminate errors

To err is human - so why trust something as important as dispensing medicine to fallible humans?
Most of the time, Capital Regional Medical Center doesn't.
When the new hospital (formerly Tallahassee Community Hospital) opened in late August, one of its most talked-about changes was its robotic pharmacy assistant, nicknamed Phred.
"Unlike humans, robots don't judge pills by their names, shapes or colors," said Don Killingsworth, pharmacy director for CRMC, which is owned by HCA.
"You (pharmacists) have to read the name and strength," Killingsworth said. "The robot is only looking at the bar code."
According to Killingsworth, a three- to four-day supply of 650 different drugs is stored in the metal-and-glass room that houses the robot. Each of those drugs is assigned a bar code, packaged in individual doses and stored on separate rods inside the robot.
Each patient also is assigned a bar code, which is used throughout the hospital. The robot uses the patient bar code, as well as the bar codes on individual medications, to make sure they match up.
If the order is correct, the robot will use its long metal arm to pull the medication and drop an individual dose into an envelope marked with the patient's name and appropriate bar code.
