Here’s a cool video of Boston Dynamics SpotMini quadruped robot opening a door for its SpotMini buddy. Opening a door – while quite a simple move for humans, can be quite a feat for robots. Here we see the first SpotMini end up being helpless at the door (no surprise there), until its buddy shows up with an arm-like attachment to open the door. The bot opens the door, uses its foot to keep it ajar, and then pulls it open. Simple, eh? Quite a leap for bots though.
