As facilities struggle to staff, help may soon be available in the form of a meal-delivering robot. Yujin Robot of South Korea makes GoCart, which will be tested at several nursing homes in the United States later this year. The robot maps the environment and uses an array of sensors and cameras to autonomously carry out its deliveries, without interfering with people or other objects. It connects with any facility’s existing IT system and works with smartphones, tablets, PCs and smart TVs, according to the manufacturer.
