In the first clip entitled 'Weird Robot in Westfiled' baffled shoppers are filming the seemingly shy robot with their mobile phones.

The robot appears to be waving a shoppers and at one point is heard to say 'hello'.

Another clip uploaded earlier today shows the robot in what appears to be in London's Regents Park being confronted by a feisty Scotty dog.

It is not currently known who was responsible for the robot's presence.

The description on the second video said: 'We were out walking our dog in regents park and came across this robot!

'Very weird, he was out there...alone, nobody was looking after him! Just zipped off down the path after we filmed this.'
