You could argue that the door handle has had a disproportionate influence on modern robotics. It was the humanoids of the Darpa Robotics Challenge, that were tasked with opening doors, and it was those machines that helped drive robots to where they are now.
Today Boston Dynamics posted a video of its SpotMiniquadruped robot extending an arm out of its head to turn a handle. With the dexterity of a tray-carrying butler, it uses its foot to prop the door ajar, then elbows it all the way open for its (armless) SpotMini friend to walk through. At face value, it’s a pretty incredible feat. But it’s also an interesting twist in the quest to make robots that get along with a world built by and for humans.
Maybe the Darpa Robotics Challenge had it wrong with humanoids after all.
