The measurement equipment used in land surveying has evolved significantly over the last 20+ years. Electronic distance measurement (EDM), electronic total stations, and electronic data collection are examples of three technologies that have made a big impact.
More recently, there have been technological developments that have enabled one person surveying. Global positioning systems (GPS) is a main stream technology that is present in phones and automobiles. However, robotic total stations (aka, robot) are not as familiar to people outside of the land surveying profession.
A robot operates similarly to a standard total station, with the major exception that measurements using a robot can be performed by one person, operated remotely from an instrument controller at the prism pole. An instrument operator is not necessary.
The advantage of using a robot over a GPS system is the robot can operate in locations with tree canopy or other similar obstructions that prevent a clear view of the sky. The disadvantage of using a robot instead of a GPS is that a robot requires a direct line of sight with the prism rod, whereas a GPS only needs a clear view of the sky.
