All our robots are equipped with a S300 Expert (2 m) laser scanner from Sick as standard. On many models, a second laser scanner can be added as an option to increase the field of view or even provide complete coverage around the robot.
Protective fields can be defined in the field of view of the laser scanners. As soon as an obstacle is detected in these protective fields, the robot switches to the safe stop.
The PSENscan offers a finer angular resolution than the S300 which results in very good environmental maps. As it currently cannot support a speed-dependent protective field switchover, its use in the MP-400 or MP-500 is only reasonable in special cases.
For larger and more complex robots, especially for mobile manipulators, it makes sense to use a safety controller such as the Flexi Soft from Sick. Almost any safety component can be connected to the Flexi Soft. Their interaction can then be freely programmed and precisely adapted to the respective application. In many applications, safe operation of autonomous robots is otherwise not possible.
