Portugal Colonial - 'Alter-Ego': An Italian hospital's little robot carer

Named "Alter-Ego", the 1.2-metre tall robot can stand in for a doctor working remotely, bring a patient a bottle of water or guide them to treatment.

Daniel Senna, a 31-year-old patient at the Maugeri Hospital, transmits his pain level on a screen attached to the robot's chest.

"Hi Dani. How are you? Do you need anything?" Ego asks wheelchair-bound Senna, as the data collected is sent instantly to the ward's nurses.

The robot has been undergoing testing since April in a department which treats people with amyotrophic lateral sclerosis (ALS), a neurodegenerative disease.

"At first, we were afraid the patient might have a negative reaction," Christian Lunetta, director of the hospital's neuromotor rehabilitation department, told AFP.

But they soon were "very satisfied, because the robot was designed to spark curiosity and its movements, or at least its functions, suggest a wide range of potential uses".

The project is a collaboration between the Italian Institute of Technology and the University of Pisa in northern Italy and is currently being remotely controlled by an operator.

From July, the robot will work autonomously.

The rise of artificial intelligence (AI) has significantly accelerated progress in robotics but robots still need a great deal of training to operate independently.

The aim with the Milan experiment is to work with patients and caregivers to better understand the limits of what a robot can or should do in a hospital ward, said Manuel Catalano from the Italian Institute of Technology.

"Alter-Ego" could also eventually assist patients and their caregivers at home, he said.

Lunetta pointed out that hospitals "have repetitive tasks" which "could be delegated to a good robot".

"This would also allow us to better value human beings, giving them the time to focus on the human relationship they must maintain with the patient," he said.

Nurses monitor patients while handing out medicine, picking up signals about physical or mental health.

"Alter-Ego" may seem capable but "no-one has considered directly delegating the administration of pills" to it, neurologist Rachele Piras said.

It can be helpful in other ways though, "as the (neurodegenerative) disease progresses", she said.

Patients could find it liberating to be able to directly ask the robot for things, while doing so would also reduce the tasks of a caregiver, allowing him or her to "revert to simply being a companion, mother or daughter".
