Perhaps you've just conjured a machine with a rigid, metallic exterior. While robots armored with hard exoskeletons are common, they're not always ideal. Soft-bodied robots, inspired by fish or other squishy creatures, might better adapt to changing environments and work more safely with people. Roboticists generally have to decide whether to design a hard- or soft-bodied robot for a particular task. But that tradeoff may no longer be necessary.
