Function
The Robotino bumper bar ensures that in the event of a collision, program execution and
movement are interrupted.
Configuration
In the web interface of Robotino you can deactivate the program interruption when
switching the shock bar. This safety function is activated by default.
Assembly and connection
The bumper is attached to the bottom edge of the Robotino chassis and connected to the
power electronics board.
Technology
The collision protection sensor of the Robotino is a so-called safety edge. This safety
edge consists of a plastic profile of different shapes with integrated switching
chamber. There are two separate conductive areas in the switching chamber. These are
short-circuited when the safety edge is pressed and thus generate a signal for the
evaluation device. The safety edge used in the Robotino operates according to the
quiescent current principle so that a possible cable break can be detected and the
Robotino can be stopped. The quiescent current is an electrical current that flows
continuously in a circuit, even if it is not active. If this current does not flow,
there is a cable break or destruction of the safety edge.
