A woman walking her dog was in for a surprise when she came across something a little more unusual also out for a stroll.
It's not every day that you stumble across one of the biggest companies in the world testing out their robot technology, but that's exactly what happened - and she caught it all on camera.
The Google-owned Boston Dynamics robot, Atlas, has been caught on camera before in official videos, but never before "in the wild".
Atlas is one of several types of robots Boston Dynamics is working on - others are more dog-like machines. Perhaps the dog, non-plussed by Atlas, might take more interest if it ran it to BigDog or Spot.
