Created by an international team of EU-funded researchers, it can interact with patients, provide practical information and answer questions to help people navigate around the hospital.\u003C\/p\u003E\u003Cp\u003ETrials of the orange-and-white robot named ARI have shown promise, according to the team at the Broca Hospital, which specialises in day care for elderly patients with conditions like Alzheimer\u2019s and other cognitive impairments.\u003C\/p\u003E\u003Ch2\u003ECutting through the noise\u003C\/h2\u003E\u003Cp\u003EThe challenge was to have the robot understand when it is being spoken to in a busy environment, be able to talk to different people and answer their questions while appearing friendly and non-intimidating to the patients.\u003C\/p\u003E\u003Cp\u003EIn a video filmed by researchers during trials, an elderly lady approaches ARI to ask directions to office 253.
