Claim 4:
5. A vehicle comprising:
a light detection assembly having:
a light emitter configured to emit a first light at a first wavelength;
an optical filter, wherein a second light is emitted from a navigation marker illuminated by the first light and corresponding to a second wavelength can propagate through the optical filter and the optical filter blocks the first wavelength; and
an optical sensor aligned with the optical filter and configured to sense the second light propagating through the optical filter;
a computing device configured to:
determine optical data based on the second light sensed by the optical sensor, the optical data indicative of the second wavelength;
determine the optical data corresponds to a first vehicle action based on the second wavelength and a database, the database comprising a first vehicle action and a second vehicle action and associating the first vehicle action with the second wavelength and the second vehicle action with a third wavelength; and
cause the vehicle to perform the first vehicle action based on the optical data corresponding to the first vehicle action.
