Figure 9.9. Objects below 30 mm from the ground are not detected by the camera. This value
increases by 10mm per meter from the robot.
The 3D cameras have the following limitations:
•
They can only detect objects in front of the robot, unlike the full 360° view of
the laser scanners.
•
They do not detect transparent or reflective obstacles well.
•
They do not detect holes or descending stairways.
•
The cameras are not reliable at determining depth when viewing structures
with repetitive patterns.
•
The cameras may detect phantom obstacles if they are exposed to strong
direct light.
Proximity sensors
Using infrared light, the proximity sensors point downwards and detect low
objects around the corners of the robot outside the field of view of the safety
scanners and 3D cameras.
