Abstract
Exemplary embodiments provide enhancements for soft robotic actuators. In some embodiments, angular adjustment systems are provided for varying an angle between an actuator and the hub, or between two actuators. The angular adjustment system may also be used to vary a relative distance or spacing between actuators. According to further embodiments, rigidizing layers are provided for reinforcing one or more portions of an actuator at one or more locations of relatively high strain. According to further embodiments, force amplification structures are provided for increasing an amount of force applied by an actuator to a target. The force amplification structures may serve to shorten the length of the actuator that is subject to bending upon inflation. According to still further embodiments, gripping pads are provided for customizing an actuator's gripping profile to better conform to the surfaces of items to be gripped.
