In what may be the sweetest instance of robot-on-robot kindness we’ve seen this week, this group of ‘Thriller’-dancing robots slows down and waits for one of their number to recover when a researcher makes it fall down.
Like a human dance group, the robots constantly stay in sync with each other and with the music (although they’re keeping their place in the dance wirelessly rather than visually). When the other robots notice that one has fallen behind, they start dancing more slowly.
When the fallen robot stands up, it wirelessly receives a starting position from its fellows — but it can’t get its arms and legs in order immediately, so the other robots are further in the dance by the time it gets going, and so it dances more quickly to catch up. Eventually it gets resynchronized, and the dance goes on at its original speed.
