A Robotic Total Station, unlike a Total Station, allows the operator to control the instrument via remote control. This eliminates the need for an assistant staff member as the operator holds the reflector and controls the total station from the observed point. Although Robotic Total Stations were once a tool only used by surveyors they are more commonly being used today by contractor and construction businesses.
Today there are many companies that manufacture these robotic total stations. Some of these companies are Trimble, Leica, and Topcon.
How Total Robotic Stations Work
Although each robotic total station has its own benefits and features, all of the elements for each manufacturer are the same. Each station is servo-motor-driven which means they have the ability to measure angles both in the X & Y (horizontal planes) and in the Z (elevation axis). Due to all this, measurements are very accurate and precise and usually measure within 3 seconds of accuracy or less.
Electronic distance meters (EDMs) are found in robotic total station just as they are present in total stations. By laser technology or infrared sensors, EDMs are able to measure distances within millimeters accuracy. The target found within the station involves a prism that reflects light back to the instrument. This light determines a remote measurement and is reported through radio communication to the electronic data collector. This process is also known as telemetry. The use of these prisms, servomotors, and infrared technology allow robotic total stations to search and lock onto targets automatically. This unique feature enables surveyors to easily move the station around jobsites without losing targets.
Because of its importance in construction layout, our crews uses the latest Trimble and Leica Robotic Total Stations. Also,the Benchmark Group provides Robotic Total Station Training to whoever is interested in learning how to effectively use them.
