Problems solved by technology

Although such technology slightly improves puncture resistance and enhances the overall advantage, this type of actuator precludes modularization or the possibility of repairing such reinforcements without discarding the entire actuator
In addition, fiber-reinforced actuators exhibit fragile rubber surfaces when facing the environment, and delamination of elastomer fibers, limited fatigue life, and poor environmental resistance are prevalent.

Abstract

A hub assembly for coupling different grasper assemblies including a soft actuator in various configurations to a mechanical robotic components are described. Further described are soft actuators having various reinforcement. Further described are and soft actuators having electroadhesive pads for improved grip, and / or embedded electromagnets for interacting with complementary surfaces on the object being gripped. Still further described are soft actuators having reinforcement mechanisms for reducing or eliminating bowing in a strain limiting layer, or for reinforcing accordion troughs in the soft actuator body.

Description

[0001] related application [0002] This application claims priority to US Patent Application Nos. 62 / 051,546 and 62 / 051,571, both filed September 17, 2015.
