This study explores fluidic artificial muscles (FAMs) actuated by hydraulic and pneumatic systems in a variety of environments. FAMs are lightweight, inexpensive actuators which are simple to align and inexpensive to build. By designing, constructing, and testing a hydraulic pressurization system along with a variety of FAMs, the project will evaluate the design characteristics of an effective bimodal soft-robotic system. It investigates FAMs toward operation in both atmospheric and underwater environments.
