Abstract

A multi-axis rotary actuator includes a payload support configured to be rotatable about a first axis, a disk surrounding at least a portion of the payload support, and an elevation wheel rotatably coupled to the payload support. The disk is configured to be rotatable about the first axis. The elevation wheel is configured to be in contact with the disk and to be rotatable about a second axis perpendicular to the first axis. The actuator can include a mirror or other device coupled to the elevation wheel. The mirror or other device is configured to be rotatable about the first axis and the second axis as the payload support and the elevation wheel rotate about the first axis and the second axis, respectively.
