Robots are now working in a hospital and can replace the jobs of four people each.

Eight of the robots , called Noah, are working in a busy hospital, where they run errands for nurses.

Each of the little bots can carry documents and medicine weighing up to 330kg, but bosses at the hospital believe they are capable of much more.

The Noahs, which are based at the Guangzhou Women and Children Medical Center, in the capital of South China’s Guangdong Province, currently operate between the pharmacy and the nurses station.

Using GPS technology, a Noah bot is able to navigate the hospital’s complex wings with ease and can carry 10 times as much as one human staff member.

The hospital estimates the machines will save nurses up to 1,207 miles of walking every year.

The intelligent Noah bots are programmed with phrases such as "Here I go!", "I’m entering the lift!" and "I’ve been obstructed!" to notify their human colleagues throughout the day.

Other benefits of using the Noahs includes sanitation, as the wheeled and lockable cabinet hauled around by the robots guarantees contamination-free transport of vital hospital equipment and medication, further lowering the risk of human error.

The Guangzhou Women and Children Medical Center has over the years made a name for itself as a facility that is keen to pioneer the use of technologies that benefit those providing and requiring hospital treatment.

The hospital became the first in China to allow appointments through mobile phone applications and cashless payments through mobile devices too.
