Abstract

In some examples, electrical wires are routed between a base and a rotating component through a plurality of clockspring passes. The wires can be, for example, ribbon wires or another type of wire. Each wire of the plurality of wires is coiled around a structure of a clockspring pass of the plurality of clockspring passes, and is configured to tighten or loosen around the structure as the component rotates relative to the base about at least one axis.
