For instance, in
Ningbo Dingming Machinery Manufacturing Co.,Ltd otic systems with other types of soft actuators, some require both high stiffness and low stiffness to undertake different roles . Upon integration, the soft low-stiffness parts can perform large actuation strain to change the 3D shapes on demand to passively adapt to variable environments, while the relatively rigid parts can provide high precision and generate or sustain high force to actively produce external work and complete complicated tasks.
