2.2 Correct use

The NAV350 laser positioning sensor is intended for use in industrial environments. When used in residential areas, it can cause radio interferences.

The NAV350 is used to determine the position of automated guide vehicles (AGV) at a point on the programmed route. Fitted to an AGV, the NAV350 continuously measures the positions of reflectors detected as well as the surrounding contour. Depending on the operating mode selected, the NAV350 outputs to the AGV’s vehicle computer the position of the reflectors, or its own position, as well as the distance, the angle and the remission of the surrounding contour seen. The vehicle computer can use this information to correct the course of the AGV as necessary to keep it to the route.

The NAV350 is a sensor for use indoors.

Important In case of any other usage as well as in case of modifications to the NAV350, e.g. due to

opening the housing during mounting and electrical installation, or to the SICK software, any claims against SICK AG under the warranty will be rendered void.

The NAV350 is only allowed to be operated in the ambient temperature range allowed (see

section 9.1 “Data sheet NAV350” on page 63).

3.2.2 Controls and status indicators

User interface

The NAV350 operates fully automatically in normal operation without the intervention of an operator.

The interactive configuration is carried out using the provided SOPAS ET configuration software. The software used for this purpose runs on a PC with the operating system Windows that is connected to the NAV350 via one of the interfaces.

Use the graphic scan view in SOPAS ET to verify the generated measured values and to verify the measurement area online. During this process, note that SOPAS ET cannot display the data in real-time and therefore does not display all measured values.

Status indicators

The LEDs signal the operational status of the NAV350.

The NAV350 has four LEDs. These visually signal the actual operational status and the sta-tus of the continuous self-check. The LEDs are on the front of the device on the NAV350.

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.

8013889/ZML0/2017-06-09

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°.

3.5.1 Navigation and landmark detection operating modes

The NAV350 has integrated application software that is used for the continuous detection of reflectors. By means of the reflectors the absolute position of the NAV350 (section 3.7

“Navigation” on page 24), the relative position of the reflectors detected (section 3.6 “Landmark detection” on page 23) or a combination of both can be output to the vehicle comput-

er connected.

In addition to navigation and landmark detection, the NAV350 can output the surrounding contour measured to the vehicle computer connected (mixed mode).

3.5.2 Influences of objects on the measurement

The majority of surfaces reflect the laser beam diffusely in all directions. The reflection of the laser beam will vary as a function of the surface structure and colour. Light surfaces re-flect the laser beam better than dark surfaces and can be detected by the NAV350 over larger distances. Brilliant white plaster reflects approx. 100% of the incident light, black foam rubber approx. 2.4%. On very rough surfaces, part of the energy is lost due to shading. The scanning range of the NAV350 will be reduced as a result.

Fig. 5: Diffuse reflection from objects

The reflection angle is the same as the angle of incidence. If the laser beam is incident per-pendicularly on a surface, the energy is optimally reflected (on the left). If the beam is inci-dent at an angle, a corresponding energy and scanning range loss is incurred (on the right).

Fig. 6: Directional reflection from reflectors

The incident radiation is not reflected diffusely in all directions by reflectors, but direction-ally. As a result a large portion of the energy emitted can be received by the NAV350. The NAV350 makes use of this situation to be able to exactly measure the positions of reflec-tors.

Possible sources of errors

Fig. 7: Possible sources of errors during the measurement

At mirror surfaces (fig. 7, on the left) the laser beam is almost entirely deflected. Instead of the surface of the mirror, it is possible that the object on which the deflected laser beam is incident may be detected.

Objects that are smaller than the diameter of the laser beam (fig. 7, on the right) cannot re-flect all the energy of the laser light. The energy in the portion of the laser light that is not reflected is lost. This means that the scanning range is less than would be possible theoret-ically based on the surface of the object.
