(TU Delft Transport Engineering and Logistics) Var, S.C.S. (Student TU Delft) Date 2023 Abstract Underwater robot tasks pose many challenges for conventional robotic systems. The current rigid robots are limited in their adaptability to the environment and the objects to be manipulated. Soft grasping of objects offers advantages due to the flexibility when dealing with, for example, living organisms, random shaped objects, and coral reefs. Additionally, conventional robotic systems face difficulties when exploring the planet's deep waters due to higher pressures and susceptibility of the often large amount of electronics to underwater conditions. Smart materials such as shape memory alloys can be more advantageous for the actuation of soft robotic underwater grippers because there is less need for complex electronic systems. Therefore, this project explores the use of smart materials for the actuation of a soft robotic underwater gripper. With this aim, three different gripper designs were made and evaluated. Various flexible materials, smart materials, 3D printing settings, numerous gripper configurations, and manufacturing methods are investigated. The gripper is intended to be a maintenance and inspection add-on for an underwater autonomous vehicle.
