A pet robot dog walked through a park and even waved its paw at passing children.

Footage shows the robotic canine standing next to the pavement and greeting families who stopped to watch it in Bangkok, Thailand on December 15.

It wore a red shirt and a blue pants, covering its metal body while its eyes glowed red on the left with a mouth being lit by a tiny blue bulb.

Curious onlookers gathered around it as it made pooch-like movements before turning to kids on an electric scooter.

Robot dogs are advanced robots designed to resemble and mimic the behaviour of real dogs. These robots often have sensors, cameras, and AI to interact with their environment, perform tasks, or even provide companionship.

China is one of the leading developers of robot technology but Elon Musk and Tesla have their own product pipelines which supporters claim will transform everyday life.

Robot guard dogs are even being used to patrol President Trump's Mar-a-Lago home in Palm Beach, Florida.
