  \class vpForceTorqueAtiSensor

  \ingroup group_sensor_ft

  Interface for ATI force/torque sensor. This class works only under
linux-like OS. It requires Comedi 3rd party. Installation instructions are
provided here https://visp.inria.fr/3rd_comedi.

  Comedi is the linux control and measurement device interface. For more
information see http://www.comedi.org.

  This class was tested with ATI Gamma 65-SI FT sensor connected to a
  National Instrument NI DAQmx PCI-6220 board.

  Synchronous F/T data acquisition is performed using getForceTorque(). The
call to the function blocks until the whole acquisition has finished.

  The following example shows how to get single measures from an ATI F/T
device each 10 ms (100 Hz).
\code
#include <visp3/core/vpTime.h>
#include <visp3/sensor/vpForceTorqueAtiSensor.h>

int main(int argc, char** argv)
{
  vpForceTorqueAtiSensor ati;
  ati.setCalibrationFile("FT12345.cal");
  ati.open();
  ati.bias();
  for(unsigned int i=0; i < 20; i++) {
    std::cout << "F/T: " << ati.getForceTorque().t() << std::endl;
    vpTime::wait(10);
  }
  ati.close();
#endif
}
