Hydraulics

Input devices such as computer mice may be rigid for now, but thanks to new hydraulic haptic tech they could someday be soft n' squishy. And that's not all … they may also "throb" in our hand to provide tactile feedback as we use them.

Scientists have discovered how an Australian jumping spider's semi-hydraulics allows it to speed jump long distances with precision while experiencing g-forces higher than those of fighter pilots. Their insights might help robotics research.
