While total stations are traditionally operated manually, they can also be operated remotely.
A total station that is operated remotely is called a robotic total station, and these types of total stations are usually capable of taking more detailed measurements. A robotic total station can usually be operated from a significant distance.
Once your robotic total station is properly setup over its point, the operator then uses their reflective target and places it at key points of measurement. The robotic total station will scan for the reflective target and lock on allowing the surveyor to tackle a complex survey solo.
