To provide a drive force transmission device that is capable of transmitting elastic energy of an elastic member to an output shaft with a simpler structure than the structure of the related art. A drive force transmission device includes a first shaft (input shaft), and a second shaft (a crankshaft, a crank disc, an intermediate shaft). A force is applied to the second shaft in a predetermined direction of rotation and in a direction opposite to the direction of rotation. The force varies in strength in association with the rotation. The first shaft is connected to the second shaft, and transmission of a drive force of the first shaft to the second shaft is enabled.

Actuation systems and methods are disclosed. Such systems may comprise a motor having a drive shaft, one or more modules coupled to the drive shaft, each module comprising one or more energy storage elements and one or more actuating members connecting the one or more energy storage elements to one or more degrees of freedom, which are configured to actuate in response to a discharge of energy from the one or more energy storage element, and a plurality of clutches associated with each module to couple the energy storage element of the module to the drive shaft of the motor and to control an energy state of the energy storage element independent of energy storage elements of other modules.

A gearbox includes a planetary gearset, an input shaft coupled to a sun gear of the planetary gearset, and an output shaft coupled to planet gears of the planetary gearset via a carrier. A constant torsion spring is coupled to a ring gear of the planetary gearset. The constant torsion spring is capable of preventing the ring gear from moving when a torque at the output shaft is below a threshold. The ring gear winds the constant torsion spring in response to the torque exceeding the threshold.
