Safety-related functions
The following functions are integrated within the robot itself and cannot be modified or used
with other applications. The following list introduces the main safety-related functions
integrated in MiR250 Shelf Carrier:
•
This function ensures that the robot stops before it collides with personnel or an object. If
the laser scanners detect an object or person within a defined Protective field, the robot is
brought to a stop. The function determines what the current speed of the robot is based
on data from the motor encoders, and the function switches between predefined
Protective fields accordingly. The faster the speed, the larger the Protective field is.
•
The safety system monitors if the motor encoder data indicates that the speed of each
motor is above the limits for maximum rated speed. If the limit is exceeded, the robot
enters Protective stop.
•
The safety system monitors if the motor encoder data indicates that the speed difference
between the two motors are above predefined limits. If the limit is exceeded, the robot
enters Protective stop.
•
MiR Shelf Carrier 250 has two Emergency stop buttons. When one of the buttons is
pressed, the robot goes into Emergency stop.
