Digital Mechatronics and Polymer Muscle Actuators for Robotic Systems

Time and Place
Auditorium (NSH 1305)
Digital mechatronic devices approximate the motion of continuous mechanisms by using larger numbers of binary Degrees-of-Freedom. Digital mechatronic devices have excellent repeatability, are reliable, robust and are simple to control. Artificial muscle actuators that are made of elastomers are ideally suited digital mechatronic devices. These actuators have unique properties such as very large strain and large forces. They are light and inexpensive. This makes them appropriate for many diverse applications, from disposable medical devices to space systems. Using polymer actuators in binary devices overcomes some of their limitations, such as internal creep, which limit their use in more conventional designs. This presentation will include recent analytical and experimental studies of the fundamentals of polymer actuated mechatronic devices. Applications addressed will include their potential as key elements in future planetary exploration systems and their current potential applications in medical robotics.
