3.4 Applications
AGV line guidance based on contour and reflector measurements (mixed mode navigation):
• shuttle systems
• freely moving forklift
• truck loading
• general automated guided vehicles
3.5 Operating principle of the NAV350
The NAV350 has an opto-electronic laser measurement system that electro-sensitively
scans the contour of its surroundings in a plane with the aid of laser beams. The NAV350
measures its surroundings in two-dimensional polar coordinates. If a measurement beam
is incident on an object, the position is determined in the form of distance, direction and
remission.
Fig. 3: Measuring principle of the NAV350
From the propagation time that the light requires from emission to reception of the reflec--
tion at the sensor the NAV350 calculates the distance to the object.
Scanning takes place in a sector of 360°. The scanner head rotates at a frequency of 8 Hz.
During this process, a laser pulse and therefore a distance measurement is triggered after
an angular step of 0.25°.
