CHAPTER 2. GENERAL HARDWARE INFORMATION
2.6. SAFETY INSTRUCTIONS
2.6.3.2 Laser Scanners
The safety approved laser scanners can monitor user-defined safety fields in front of or around the robot which are
dynamically activated according to the current velocity of the platform. If required these fields can also be activated by
an application specific control software. In this case only the control software is responsible for the correct activation
of the safety fields according to the current condition
Note:
Please note that in omnidirectional robots the safety fields can only be activated by software and not depending
on the robot’s speed.
As soon as a person or obstacle is detected within the currently active safety field the robot is immediately set to
emergency stop. The stop will be reset automatically after the field has been cleared. No manual reset is required in
this case.
The laser scanners have been approved as safety device with Performance Level d and SIL2. They fully replace the
mechanical safety bumpers which have been required for autonomous vehicles in their early days.
2.6.3.3 Special Functions
In case third-party software is meant to run on the robot or on the remote control computer this software can be enabled
to trigger an emergency stop and or to reset the safety system. Additional safety devices can also be integrated into
the mobile robot.
Please contact Neobotix if you plan to implement any special functions.
2.6.4 Cooperating with the Robot
2.6.4.1 Close Proximity
As long as the robot is not in full emergency stop, a minimum distance should always be kept. Direct contact to the
active robot system is to be avoided.
Warning:
Climbing up onto the mobile platform and / or riding on it are not allowed at any time.
2.6.4.2 Medium Proximity
When approaching the robot or working in its presence, increased attention and caution are required. The safety
features of the mobile robot have to be set at such a level that imminent dangers can be detected and that injuries or
damages can be avoided.
In case the safety features have to be reduced due to the requirements of the process it might be necessary to prohibit
the presence of people in the robot’s surrounding. In these cases only the owner of the robot system can be held
responsible for the safe operation.
2.6.4.3 General Surrounding
As long as the safety features of the mobile robot are set up properly, the presence of people and vehicles in the robot’s
wider working area is allowed. Please contact Neobotix for further advice if needed.
All people working in the same area as the robot should nevertheless be informed about the robot’s behaviour and the
possible dangers. Appropriate behaviour and consideration are necessary.
