The pilot scheme – the first of its kind in the UK – has seen the creations disinfecting street furniture and sanitising high-risk touch points in public areas.
It is hoped the initiative – which is also being tried at Leeds Bradford Airport – will reduce risk of contagion to both visitors and cleaning staff.
And developers at Self Repairing Cities – a Leeds University-led research project – say the results so far are highly encouraging.
Dr Bilal Kaddouh, assistant professor at the centre’s school of mechanical engineering, said: “The robots were able to identify the objects that they needed to clean, and they were able to manoeuvre in the public spaces. The robotic arms effectively delivered the disinfectant on to the target surfaces.”
The machines themselves are fitted with navigation tools, computer vision and artificial intelligence which combine to help them identify surfaces in need of cleaning and clear of humans. They then spray a mist of diluted alcohol onto the objects.
They are an adaption of an existing machine which was originally designed to inspect, and conduct repairs on, major infrastructure such as pipes and bridges.
But while the innovation is a first for a UK city, the coronavirus-killing droids are not the only ones in use here.
Heathrow Airport in London introduced UV cleaning robots to minimise the risk of travellers contracting Covid-19 last month.
