Watch: Robot dog plays among the fountains at Granary Square in King's Cross

Visitors to King's Cross's Granary Square last Thursday (February 15) were treated to the unusual sight of a robot dog going for a walk.

Children looked on as it played among the fountains.

The robot is a Spot model made by Boston Dynamics, and was branded 'Bidvest Noonan'. Neither company has confirmed whether there was a reason for the outing beyond a regular walkies.

Boston Dynamics' website says it builds robots "for the real world".

"We build products robust enough to excel in the toughest working conditions - all while staying agile enough for human-purposed environments," according to its website.

Spot is designed to provide analysis and insights at commercial premises.

"From factory floors to construction sites to research labs and beyond, Spot works so your team can excel," writes Boston Dynamics.

"As a dynamic sensing platform, Spot provides valuable insights into routine operations, site health, or potentially hazardous situations. With Spot, your team can focus on the things that matter most, while staying out of harm’s way." Bidvest Noonan provides outsourced services such as cleaning and security.

Granary Square is a canalside district, next to King's Cross, with a variety of shops and restaurants.
