Boston Dynamics' four-legged robotic dog, Spot, has been deployed in the Bishan-Ang Mo Kio Park in Singapore in an effort to assist visitors with maintaining safe distances from each other. The bot will patrol a 4-mile area of the park and send back 'video analytics' which can be used to estimate the number of park-goers. According to a statement, Spot's cameras will not store anyone's personal information or track specific individuals.
