In recent times,Soft robotics is a growing field which relies on mimicking locomotion mechanisms of soft bodies existing in nature to achieve smooth and complex motion.
Soft robots are robots that are flexible and unlike their hard-edged cousins can be used to perform more delicate manoeuvres, such as reaching into difficult crevices or holding onto delicate objects.
Such robots are usually made of liquid crystal elastomers, which are polymers having viscosity and elasticity.
Soft robots are primarily composed of easily deformable matter such as fluids, gels, and elastomers that can match certain materials, in a process called compliance matching.
Compliance matching is the principle that materials that come into contact with each other should share similar mechanical rigidity in order to evenly distribute internal load and minimize interfacial stress concentrations.
