Project Definition

This project is the next in a line of projects using McKibben muscles, and is intended to develop additional biomimetic robotic capabilities for the Lamkin-Kennard laboratory using soft pneumatic actuators. Specifically, this project is designed to prove the feasibility of McKibben muscles for use in underwater robotic applications, and to develop core technology and a platform for other teams to use in the future.

Additionally, the result of the project, a robotic fish, could be used for exploration, surveillance, or research purposes to study underwater propulsion.

The project specifically seeks to develop a soft-bodied pneumatic fish that looks, moves, and feels like a fish. The robotic fish should be capable of swimming forward, backward, and turning, most likely using Body Caudal Fin propulsion, and the primary mechanism for generating the swimming motion must be McKibben muscles.

The Week 3 presentation of the Problem Definition phase can be seen here.
