Remote-controlled robot arms allow submersible operators to perform tasks underwater. But can you imagine a rigid metal limb interacting with something as fragile as jellyfish or corals? To be able to capture or interact with marine life, scientists need something softer that can touch delicate living things without squishing them to death. That's why a team of scientists from Harvard's Wyss Institute has developed a soft robotic arm that can "move with unprecedented dexterity to grasp and sample delicate aquatic life." Scientists from the institute have been developing soft robots for marine research for quite some time.
