    摘要: In one embodiment, a mechanically over-damped actuator includes an output link comprising a lever and a torsion spring associated with the lever, wherein the lever has an initial equilibrium position and is pivotable about a pivot axis, wherein the spring opposes pivoting of the lever away from its initial equilibrium position such that the spring tends to return the lever to the equilibrium position.

    摘要: In one embodiment, an electromagnetic soft actuator includes a first soft outer member comprising a soft internal electrically conductive coil, a second soft outer member comprising a soft internal electrically conductive coil, and a soft inner shaft on which the first and second soft outer members are mounted, the first and second soft outer members being linearly displaceable along a length of the soft inner shaft, the soft inner shaft comprising a permanent magnet, wherein the first and second outer members linearly move under an electromagnetic force relative to the soft inner shaft and each other when an electric current is applied to the soft internal electrically conductive coils.
