UNDERSTANDING AUTONOMY
The Nilfisk Liberty SC50 can function autonomously meaning that it functions (operates) on its own, without operator involvement. The machine
can be trained to clean an area independently and actively maneuver around certain obstacles.
Components that make up the Autonomy system, and their basic function, include the following (shown in Figure 1-1):
•
3-D Camera (45) - provides a three-dimensional image of the area in front of the machine.
•
2-D Mapping Laser (14) - provides detection of obstacles in front of and to the left of the machine.
•
Drop-off Safety Lasers (16) - detect drop-offs, or major changes in floor elevation.
•
2-D Safety Lasers (17), located at front corners of machine – aides in collision prevention and presence detection in the area of an
operating machine.
•
Remote (AA). This allows the exchange of status information between the operator and the machine.
•
Autonomy Box (46). This is the primary computer for safety during operation.*
•
Computer software Interface, (not shown). Defines how the autonomous control system interfaces with machine control software and
control system.

LOCATION TAG
The machine uses a Location Tag to identify its “Home Position” within the building.
IMPORTANT! No plans can be created until the location tag has been installed and identified by the machine.
1 See Figure 2-2. The Location Tag (44) should be mounted permanently on a wall where the machine will have an unobstructed view of it,
preferably near where the machine will be charged every day.
2 Place the location tag in an area where there are not movable objects (i.e. garbage cans or other equipment). The machine records
information when setting the home position, if there are new obstacles each time within the vicinity of the location tag, the recorded plan will
shift.
3 Mount the Location Tag to the wall at a maximum height of 4’ (1.2 m). This ensures the tag will be within view of the machine’s 3-D camera
(3-D camera cannot see above the height of the steering wheel). The machine must be driven to the location tag and parked perpendicular to
the wall to properly read the tag. Park the machine about 3’ (1m) away from the tag.
4 The top edge of the Location Tag must be level with the floor.
5 If a machine is operated on multiple floors of a building, it will need a unique location tag for each floor. In a building with four floors, four
different Location Tags would be required; one for each floor.
6 If the area to be cleaned is very large more than one location tag may be needed per floor. Have a location tag within 10-20m of the path
start if at all possible.
7 If a machine is operated in multiple buildings, it will need a unique location tag for each floor of each building.
