摘要： Embodiments of a series elastic actuator (SEA) disclosed herein include an elastic component coupled in series with a motor, wherein the elastic component comprises a pair of springs arranged concentrically around a central shaft of the housing for transmitting force to a mechanical ground of the SEA, and one or more spring support mechanisms arranged within an inner circumference of the springs. Some embodiments of the SEA may also include a spring deflection sensor, which is coupled within a recess formed within the mechanical ground of the SEA and configured to sense the force transmitted to the mechanical ground of the SEA.
