A new hospital ward run entirely by robots has opened in Wuhan, China, in a bid to protect medical staff from contracting the coronavirus.
On 7 March, about 200 patients exhibiting early symptoms of covid-19 were ushered into the new ward, which is in a converted sports centre in Wuhan, the city where the coronavirus outbreak started.
The robots deliver food, drinks and drugs to the patients, and keep the ward clean. Some have a humanoid head, arms and upper torso but a wheeled base, while others look more like a box on wheels. The machines can move around autonomously but are under the observation and control of staff outside of the ward.

The trial is a partnership between CloudMinds, a Beijing-based robotics firm, and mobile operator China Mobile, along with Wuhan Wuchang Hospital, an institution at the heart of early efforts to contain the virus. The hospital鈥檚 director Liu Zhiming died of the disease last month.
The temporary ward was initially established as a human-run clinic, but has now been turned over to the robots after a week-long upgrade. Engineers mapped the area and uploaded the information to a cloud server for the robots to use as they move through the ward.
CloudMinds CEO Bill Huang says the ward will be a pilot case for future initiatives. 鈥淭his is China鈥檚 first-ever entirely robot-led ward and an opportunity to test the capability of the technology and how we work together,鈥� he says.
Robots will look after patients who aren鈥檛 acutely ill but who need basic medical care. If they recover, they will be sent home. If their health problems become more acute, they will be transferred to the human-run hospital.
During their stay, patients wear bracelets fitted with sensors to measure their heart rates and temperatures. This information is displayed on a large screen outside the ward for doctors and nurses to access along with other health information. Medical staff can also use the screen to assign the robots their next task.
鈥淭he staff have a much better view of how things are going and can immediately find out if something isn鈥檛 right. I think it鈥檚 a very high-tech and new way of trying to run hospital,鈥� says Huang.
Patients may also welcome the novelty, he says. 鈥淎s we developed the plan, I talked to staff in the hospitals. They say the patients are very bored being isolated, so they love to see the robots.鈥�
The hospital and CloudMinds are working closely with China Mobile to ensure that the local mobile network鈥檚 signal strength and capacity are powerful enough to enable the robots to operate effectively and without a loss of connectivity. 鈥淐hina Mobile will boost the signal if necessary,鈥� says Huang.
Chenguang Yang at the Bristol Robotics Laboratory in the UK says this kind of experiment is extremely promising but cautions that there may be difficulties. 鈥淭here will be lots of people moving around in a hospital ward. It will be a major challenge for robots to work in such a dynamic place.鈥�
He also notes that the robots will need to physically interact with the patients in a safe way. 鈥淩obots that share space with humans, also known as cobots, need to reach very high safety standards, otherwise it鈥檚 simply too dangerous.鈥�
