Spot, the robot dog, is equipped with cameras and sensors to help it estimate the number of visitors and reduce the number of park patrons amid the COVID-19 pandemic. "For your own safety and for those around you, please stand at least one metre apart. Thank you," Spot says as it patrols Bishan-Ang Mo Kio Park in Singapore as part of a two-week trial. The government says its cameras will not be able to track specific individuals and no personal data will be collected. Singapore, an island nation of approximately 5.7 million people, is grappling with one of the highest numbers of COVID-19 cases in Asia. It is also using a fleet of 30 drones to monitor crowd levels in public parks, which have remained open during a lockdown that began in early April.
