Soft actuators tackle hard jobs in adverse work environments

For more than 50 years , air actuators have played a key role in many pneumatically powered machines.

Instead, the simple and cost-effective design somewhat resembles a flexible rubber bellows. But construction is similar to that of a car tire, giving the devices toughness, pressure resistance, and dimensional stability.
