... presents a realistic scenario in which MU pressure is controlled by a hydraulic servo valve. As a result, the overall bundle force exhibits a sharp decrease during recruitment state transition while the MU being recruited is below the onset pressure. fluidic artificial muscle variable recruitment...

... Abstract Variable recruitment fluidic artificial muscle (FAM) bundles consist of multiple FAMs arranged in motor units that are sequentially activated as load demand increases. The conventional configuration of a variable recruitment FAM bundle requires a valve for each motor unit, which...
