This paper presents preliminary results on the development of a novel Variable Stiffness 3 DoFs wrist. The proposed design can actively and continuously vary its overall stiffness thanks to the redundant elastic actuation system, using only four motors. The employed mechanical configuration achieves a compact and lightweight device that, thanks to its anthropomorphous characteristics, could be suitable for prostheses and humanoid robots. Therefore, thanks to its variable stiffness and embedded compliance, it would improve task adaptability and safety during interactions with people and objects. After introducing the mechanical configuration of the device and the employed control strategy, this work reports promising results on the motion and stiffness behavior obtained via dynamic simulation.
