Night shifts are never fun, especially in a hospital. That’s why Nagoya University Hospital in Japan is deploying robots built by Toyota to make everything run more smoothly and decrease the workload of the nurses. The four robots, equipped with floor plans, radars, and cameras with 360 degree vision and shaped like a small refrigerator, will help move medicines and test samples around the hospital throughout three different wards. They know when and where to recharge, can be called over through a tablet, and can even ride the elevator to get around. If the robots prove successful and helpful, the hospital could see more of the bots in the future.

According to hospital director Naoki Ishiguro,

“The workload can be reduced by using robots to do tasks that people have been doing. We hope to ensure that nurses and other professionals can concentrate more on their primary duties.”
