Abstract

Research in the field of underwater (UW) robotic applications is rapidly developing. The emergence of coupling the newest technologies on submersibles, different types of telecommunication devices, sensors, and soft robots is transforming the rigid approach to robotic design by providing solutions that bridge the gap between accuracy and adaptability in an environment where there is so much fluctuation in object targeting and environmental conditions. In this paper, we represent a review of the history, development, recent research endeavors, and projected outlook for the area of soft robotics technology pertaining to its use with tactile sensing in the UW environment.

Highlights

  • In the following paragraphs of this section, we provide a few specific design developments of soft robotic end-effectors that have proved influential to UW soft robotics and relevant to the following section of tactile sensing technologies

  • Beginning with a discussion of the history of soft robots that emerged from the need for more adaptive systems, this review outlines the field of soft robotics that has emerged to reveal more distinct robotic solutions that are both compliant and acute in the nature of control

  • Some challenges remain inherent to its very nature, whereas continued development in the field of soft robotics is crucial to realize more intellectual and pragmatic systems, especially with respect to the UW environment

Summary

Introduction

Due to the rigid-mechanics hosted by more conventional robotic systems, there exists a disconnect between theoretical robot capabilities and adaptability to uncontrolled environments with varying degrees of geometric and environmental conditions This disconnect usually translates to restriction in a machine’s degrees of freedom (DOF) and its inability to interact with foreign objects of complex nature without imposing damage. The fusion of soft robotics with UW technologies has become a highly regarded solution to mitigate damage control and enhance the capabilities of interactions imposed by robotics systems on complex and foreign conditional situations [8,9,10]. The domain of UW soft robotics has the potential to pioneer the ways in which we as humans interact with the ocean through robotic control It provides enhanced physical awareness and acute-capability for engaging with nature’s organic systems as well as for interacting with human-imposed mechanical systems.
