This paper presents a new calibration
method for industrial robots. The calibration method is based on
a combination of inclinometer and LVDT measurements and is very
simple to use. The inclinometers measure the deviation from the
gravity direction of a measurement rod and the LVDT sensor
measures the length of the rod. The inclinometers can be
used without any pre-calibration and the whole equipment is inexpensive,
portable and robust.
