SpotMini, Boston Dynamics's dog-like quadruped robot, is back, and it's learned a new trick.
While opening a door is slightly old hat for a Boston Dynamics robot - Atlas barrelled through a push-bar door two years ago - SpotMini's operation is more fluid.
The robot uses its fifth appendage, an arm mounted essentially where a canine's head would be, to swiftly assess the door, locate and twist the handle, and pull the door open.
In a video released by Boston Dynamics, not only does the new-and-improved SpotMini open the door for itself, it even holds it open for its robot colleague.
A portrait of professional collegiality, this is a big step up from the solo activities of washing dishes or rolling over.
Boston Dynamics has made steady progress in their efforts to build robots that move in a life-like manner, whether it's Atlas' Homo sapiens-like saunter or SpotMini's four-legged gallop.
The SpotMini's latest development is confirmation that progress continues to march on behind Boston Dynamics's doors.
But while biomimetic robots are certainly useful - the ability to copy human motion enables these robots to dexterously manipulate objects and navigate complex terrain - they still inspire more fear than awe in many people.
Outlets such as The Verge and Popular Mechanics have noted the similarities between SpotMini and the door-opening velociraptors of Jurassic Park splendour - not exactly a calming comparison, so if you envision these robots taking over the world, you're not alone.
