  "textContent": "A robotic laser-pointing apparatus has an instrument center (710), a first rotation axis (625), a second rotation axis (640), and a pointing axis (705), with the first rotation axis, the second rotation axis and the pointing axis (705) in a known relationship to the instrument center (710). A laser source (715) provides a pointing-laser beam along the pointing axis (705). A pointing drive system aims the laser beam by rotating the pointing axis about the instrument center in response to a pointing-direction control. Focusing optics (720) having a focusing-optics drive serve to focus the pointing-laser beam in response to a focusing-optics control (725). A processor, responsive to target-position information, generates the pointing-direction control and the focusing-optics control. Some embodiments include an electronic-distance-measurement system having a measurement beam. Some embodiments provide for compensation of aiming errors of the pointing-laser beam and the measurement beam.",
