What makes a robotic station different
A conventional total station needs a person behind the eyepiece to point it at the prism for every shot. A robotic one has motors on both axes and a sensor that finds the prism on its own, aims precisely at its centre and then follows it as it moves. You are at the prism with the controller in your hand, you press "measure" and the station does the rest.
On the FOIF RS10 this is described as automatic target recognition, automatic aiming, automatic measurement and automatic tracking, with a stated automatic aiming range of 5 to 1000 metres and motor speed up to 180 degrees per second. In practice it means that when you turn and walk to the next point, the station turns with you.
What a one-person day looks like
In the morning you set the station on a known point or do a resection from two or three benchmarks. You connect the controller, tell it to search for the prism, and from then on you are alone on site with the output of two people. Staking out slab axes: you walk the pole to the approximate spot, the screen tells you how far to move, the station follows the prism, you mark the point, next one. No shouting to the colleague behind the instrument, no waiting for them to re-aim. On a roof with a solar installation it means one person sets out the mounting rails across the whole roof while the station sits on the building next door.
If the prism gets lost behind a column or a truck, the station searches for it again within a set window. That takes seconds, but on a busy site with plant moving around it will happen several times an hour and you should accept it as part of the job. With rain on the prism glass and in strong backlight the search is slower too.
When it pays off
The sum is simple if you are honest with the numbers. A robotic station costs more than a conventional one and it saves you the second person. If you have a two-person crew that stakes out and checks every day on a large site, the second person becomes free for other work and one instrument earns a full working day. With one or two slabs a month the same station sits in its case and the difference never comes back. Work out honestly how many days a year you have two people on site only because the instrument needs two, and what those days cost. If it comes to more than a few weeks, a robotic station is already in reasonable territory.
There is a second reason that is not about money. The RS10 lists an angular accuracy of 0.5 or 1 second, which is the class for deformation monitoring and precise setting out. If you measure settlement of a building, movement of a retaining wall, or erect a steel structure with millimetre tolerances, automatic aiming removes the pointing error of the human eye as well as the time. There it pays off from the first job.
When a conventional station is the sensible choice
For a small surveying firm with varied jobs, cadastre today, an excavation tomorrow, a facade the day after, a conventional station with reflectorless measurement and a good battery does more work for less money. The FOIF RTS332 is exactly that type: one-touch operation from the trigger key, endless drives for fast two-handed aiming and a stated battery life of around 25 hours, which is three days without a charger. The FOIF OTS682 adds direct recording to an SD card and built-in temperature and pressure sensors, so the atmospheric correction is not entered by hand. On a site with heavy movement of people and plant a conventional station has a hidden advantage too: there is always someone standing next to it who guards it and notices when the tripod has been knocked.
If you want a modern interface without motors, the FOIF RTS362N runs Android 11 with a large touchscreen and the SurPAD application, the same way of working as on a GNSS controller. For a team already using the A90 or A66 MAX this is convenient, because the project, the codes and the points move between instruments without reformatting.
What to expect in rain, dust and traffic
All the stations in our range are IP55 rated, which covers rain and dust in normal work but not a pit full of water. The robotic station comes with an extra condition: the motors and the tracking draw more power, and the stated battery life of the RS10 is 5 to 8 hours. For a full day carry a second battery. In thick fog or heavy snow the automatic aiming range drops and in the end you aim by hand, as with a conventional station. That is not a fault, it is the limit of the sensor. And one more thing that rarely appears in brochures: a station left alone on a tripod at the end of a site is a station someone can hit with a wheelbarrow. Fence it off, put it somewhere visible, and keep it away from the excavator's path.
Put simply, a robotic station is for a company where every day involves stakeout on a large site or precise monitoring, and where the second person has more useful work than turning screws. In every other case start with a conventional station with a good battery, and when the jobs grow, the RS10 will be waiting.
