  A new fluid-driven soft robot hand in this study uses the idea of the bionics
and has the anthropomorphic form, which is oriented to the flexible grasp
function. The soft robot hand is composed of a new kind of multi-freedom soft
finger and soft palm, which realizes the characteristic grasping function of
forehand and backhand. Combined with the fine fluid control system, the soft
hand can realize flexible grasping under high pressure, so as to realize
flexible grasping operation for different types of target objects in the
underwater environment. The soft robot hand was controlled based on water
hydraulic platform, Finally, the soft robot hand and the fine fluid control
system were connected to form the underwater soft robot hand experiment
platform.
