Several years ago, I wrote a feature for Bloomberg Businessweek about soft robotics, "in which steel skeletons and power-hungry motors make way for textiles." The idea is that soft robots, often powered by compressed air in pneumatic "muscles," are more flexible, lighter weight, and much safer for their human workmates. Above is video of automation robotics firm Festo's BionicSoftArm. From their description:
Whether free and flexible movements or defined sequences, thanks to its modular design, the pneumatic lightweight robot can be used for numerous applications. In combination with various adaptive grippers, it can pick up and handle a wide variety of objects and shapes. At the same time, it is completely compliant and poses no danger to the user even in the event of a collision.
