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.

Start-up Check
1. Remote will flash both LEDs (AC1 & AC2) and beep, when the machine is powered
ON to indicate machine and remote are properly paired together.
While the machine is operating in autonomous mode there are three interactions the
operator can have with the machine through the remote.
1- The remote can communicate to the operator by sending alerts using the LEDs
and audible beeps
2- User can request machine status information.
3- User can use the remote to pause the playback of a plan while operating
autonomously.
