Various surfaces and colours can be detected by the two included opto-electronic sensors (so-called diffuse light sensors) on the basis of varying degrees of reflectivity. The sensors can thus be used to guide the Robotino along a defined path, or to accurately stop it at a specified position.
Assembly and connection
Installation of the opto-electronic sensors is described in the manual:
The opto-electronic sensors are evaluated via a digital input at the I/O interface.
Flexible fibre-optic cables are connected to the fibre-optic unit of the opto-electronic sensor. The fibre-optic unit works with visible red light. Reflected light is detected. Different surfaces and colours result in varying degrees of reflectivity. However, a gradual change in the amount of reflected light cannot be detected.
The scope of delivery includes two opto-electronic sensors SOEG-L-Q30-P-A-K-2L (fibre-optic unit) supplied by Festo.
