  • Cheaper Joints and Digits Bring the Robot Revolution Closer

    Efforts to build robot hands and humanoids more cheaply could make them affordable enough for businesses and even homes.

    The Atlas humanoid robot, unveiled last year by Boston Dynamics, a company later acquired by Google, is a marvel. It can clamber over rubble and operate power tools. But these abilities don’t come cheap. Atlas has a price tag well above a million dollars, and it consumes around 15 kilowatts of electricity when in operation, meaning hefty power bills for its owner and limiting its practicality. “That’s enough to power a small city block,” says Alexander Kernbaum, research engineer at the nonprofit research agency SRI International. To be truly practical, he says, Atlas “needs to be many times more efficient.”
