MIT researchers made a wristband to teach robots how to do housework and surgery

Humanoid robots struggling with tasks like grasping a cup have a new teacher — a person wearing an ultrasound wristband that captures the movement of muscles, tendons and ligaments beneath the skin.

Researchers at the Massachusetts Institute of Technology developed the tool to collect data of human hand motion that could eventually help robots achieve the dexterity that has been difficult for machines to master.

“Imagine people doing housework,” said Xuanhe Zhao, an MIT professor of mechanical engineering. “We can use the data obtained by our system to train a robot to do exactly (that)........
