Tanya Beran, a professor at the University of Calgary that developed the technology, says the response to four MEDi robots that were purchased by Canada's Alberta Children's Hospital in January has been overwhelming.
"Families were driving 40 miles to see MEDi. They began asking for MEDi. Even though we only studied children five to nine years old, we have seen MEDi provide comfort to children as young as two years of age and even up to 16 years of age," she told CNBC.

"Parents told us that when they left the hospital, their children said almost nothing about the needle and told everyone they could about the robot," said Beran, founder and chief scientific officer at Calgary-based MEDi manufacturer RxRobots.
According to research from the journal Vaccine, MEDi's use reduced children's pain in medical procedures by 50 percent.
Beran said that MEDi has the most sophisticated technology on the market and helps fill a gap where there are not enough pain management experts or where parents feel anxious themselves about how to help their child.
The robot can speak 19 languages and be can be programmed to integrate culturally.
