Norman Wereley: Bioinspired pneumatic artificial muscle actuator system design for aerospace and robotics applications
Pneumatic Artificial Muscles (PAMs) were conceived by Gaylord in the 1950s, and have since been investigated for use in prosthetic and robotic devices, morphing and nastic structures, and aerospace applications. Only recently, however, have PAMs been seriously considered for aerospace applications. PAMs possess many attractive characteristics for implementation in these areas. They are simple, lightweight actuators that produce high levels of force and large, usable stroke at moderate actuation pressures (<620 kPa). The advantages of PAM actuators extend beyond their high performance levels. PAMs are naturally compliant and are highly tolerant to misalignment and impulsive loading. First, the advantages and disadvantages of PAMs relative to other smart material-based actuation technologies is discussed in terms of block force, free contraction, specific actuation force and work. This lecture also discusses applications of such PAMS to aerospace systems including space robotics for manipulator and end effectors, trailing edge flaps in helicopter rotor blades and miniaturized actuators for micro-air vehicles.
