Video shows robot dog helping with construction at UK airport

A video has surfaced showing robot dog 'Dave' helping with a construction project in cargo tunnels of London's Heathrow airport. Dave, which construction firm Mace is using, collects up-to-date live data from hazardous and hard-to-reach locations. "Dave dog has been a fantastic innovation at making sure we can perform the tasks we need to do," said Heathrow COO Emma Gilthorpe.
