Benefits

The design allowed for a clear separation of the elastic element from the drive element after the difficulties with the Dancing Santa design.

Problems

This design includes the motor in the elastic mode of the actuator and therefore substantially decreases the mechanical bandwidth of the system when the elastic element is engaged and therefore any loaded bandwidth. That is, the motor is moving when the output shaft changes torque and slows down the system. Therefore, the design was rejected in favor of designs which are not similarly inhibited.
