In a messy warehouse, a dancer’s silhouetted spine and legs begin to undulate. Illuminated only by a spotlight attached to a machine, she begins to move, tracing shapes with her arms.
But then something odd happens: The spotlight starts to move of its own accord. Responding to the dancer, it finds its own rhythm and sways side to side. It soon becomes unclear who is leading whom. What is clear is that a dance is being made, and that one partner is 9 feet high, more than 500 pounds. Called ABB IRB 6700, it is one of the largest industrial robots in the world.
