A team of Penn Engineers has devised a new electrostatically controlled clutch which enables a soft robotic hand to be able to hold 4 pounds – about the weight of a bag of apples – which is 40 times more than the hand could lift without the clutch. In addition, the ability to perform this task requiring both a soft touch and strength was accomplished with only 125 volts of electricity, a third of the voltage required for current clutches.
