The present disclosure describes devices and methods for providing movement of a payload about at least two degrees of freedom. A gimbal mechanism as described herein can provide rotation of a payload about at least two different axes, wherein the rotation about the two axes is controlled by two actuators that can be actuated independently of one another. The two actuators can be fixed in position and orientation relative to one another, such that neither actuator is driven by the other. Therefore, the gimbal mechanism can control movement of the payload about two degrees of freedom in a parallel manner. The gimbal mechanisms described herein can have a compact configuration that allows for minimizing the volume and weight of the gimbal mechanisms, while improving the stability of movement provided by the gimbal mechanisms.
