Robots That Learned to Dance
Nkechi Moreau-Hale teaches machines to move like people, and people to move with machines.
The arm is matte white and about the length of a person’s. When Nkechi Moreau-Hale steps toward it, it leans back. When she reaches, it reaches. When she hesitates, it waits, and that small pause is the result of four years of work.
Nkechi studied engineering in Lagos and dance in Paris simultaneously, flying between the two every fortnight. Her teachers in both cities told her to pick one. She built a company that needs both disciplines to exist.
Compliance as a creative constraint
Industrial robots are designed to be stiff and precise. Hers are designed to yield. The same soft-control systems that let her arms partner a dancer safely are now licensed to surgical robotics firms, where a gentle hand matters just as much.
Her duet Second Skin has toured eleven cities. Each performance is different because the arm continues to learn from its partner. Dancers describe it as unsettling at first, then oddly tender.
She is wary of the word humanoid. The goal is not to make machines look like people, she says, but to make them pay attention like people do.
The first time the arm hesitated before a turn, the whole room went silent.
