Controllable and reversible tuning of material rigidity for robot applications (2018, background): “MR fluids can be used for exoskeletons prosthetic knees to realize adaptive control of torque [80,81].”
Powered ankle-foot prosthesis to assist level-ground and stair-descent gaits (2008, methodology): “Finite state controllers have often been used in leg orthotic and prosthetic devices, such as knee prostheses (Grimes, 1976; Herr & Wilkenfeld, 2003; Koganezawa & Kato, 1987; Zlatnik, Steiner, & Schweitzer, 2002), because leg gait patterns are typically repetitive between strides and within a…”
A Quasi-Passive Leg Exoskeleton for Load-Carrying Augmentation (2007, methodology): “The knee mechanism comprised a magnetorheological (MR) damper with the MR fluid used in the shear mode, similar to that used for a prosthetic knee joint.(20) The knee variable damper could exert a maximum braking torque of 60Nm and consumed on average 1W of electrical power during walking.”
Control strategies for active lower extremity prosthetics and orthotics: a review (2015, unknown): “Many groups have successfully implemented FSCs using different numbers of activities and states with a wide variety of devices [2,3,14,24,41,44,107-109,114,117, 118,121,123,124,134,137-139,143,150,163,171-186].”
A Strategy for Identifying Locomotion Modes Using Surface Electromyography (2009, background): “However, without knowing user movement intent, the artificial limb cannot properly select the correct control mode to adjust the joint impedance [3], [4] or drive powered joint motion.”
