Architecture firm Foster + Partners has employed a robot dog named Spot, designed by Boston Dynamics, to oversee construction at Battersea Power Station in London.
The four-legged machine, which can walk up and down stairs and move across uneven ground, is being used to regularly scan the site to monitor progress at Battersea Roof Gardens.
Spot is remote controlled and follows a pre-mapped route again and again. The robot's four feet help it cope with rough terrain and it can explore sites that might be hazardous or uncomfortable for humans.
As well as its own sensors, Spot can carry up to 14 kilograms of equipment.
And she returns weekly to follow its route and perform its scan of the site.
