Helping soft robots turn rigid on demand: New type of control system may broaden robots' range of tasks and allow safer interactions with people

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. Working with computer simulations, MIT researchers have developed a concept for a soft-bodied robot that can turn rigid on demand.
