TOKYO - Millions of years after the ancestors of humans evolved to lose their tails, a research team at Japan’s Keio University have built a robotic one they say could help unsteady elderly people keep their balance.
"The tail keeps balance like a pendulum," said Junichi Nabeshima, a graduate student and researcher at the university's Embodied Media Project, displaying the robotic tail attached to his waist with a harness.As Japan greys it is leading the industrial world in seeking ways to keep its ageing population mobile and productive.
The robotic tail, which uses four artificial muscles and compressed air to move in eight directions, will remain in the lab for now, however, as researchers look for ways to make it more flexible, Nabeshima said.
