Custom Two-Axis Rotary Gimbal
This gimbal system consists of an X-RSB for the lower axis with an X-RSW driving the upper axis. The devices are daisy-chained together through a slip ring, which allows daisy-chaining power and data to the X-RSW without tangling wires as the stage rotates. This setup can easily be customized to accommodate different size working envelopes or be mounted to work with an X-RST for higher accuracy systems.
