Area Protection (Mobile) - HOKUYO AUTOMATIC UST-05LN User Manual

4.3 Area protection (Mobile)

The UST can be used for mobile applications. Figure 4-3 shows an example of an AGV (Automatic
Guided Vehicle). The UST is installed on an AGV and detects the objects while travelling along a fixed route.
Output signals 1 to 3 can be used in order to reduce the speed and to stop the AGV.
Output region 1
For example, if an object is detected in the output region 1 and/or output region 2, the AGV will slow
down and warns that an object is approaching nearer, and if an object is detected in the output region 3 then
AGV stops.
By area switching function of the UST, a maximum 31 area sets can be used according to the travel route
of the AGV. For example, while traveling in a forward direction, it monitors the front portion mainly. While
turning right, the area switches in a way that the region of the right side becomes larger (refer to figure 4-4).
Make adjustments to the detection area according to the speed of the AGV. When using the UST on an AGV,
the user needs to confirm the time and distance required for the AGV to stop completely when configuring
the output regions 1 to 3.
