When the bumper contacts an object, the robot will
touch the object, stop, move backwards, and by
default, turn between 60° and 120°, then continue
moving forward.
4.1.4 Cover Displacement Sensors
The robot has two cover displacement sensors. If an
obstacle causes the cover to be pushed backwards, the
robot will, stop, move backwards, and by default, turn
between 60° and 120°, then continue moving forward.
If the robot cannot avoid the obstacle it will register
and alarm and remain in safe mode.

4.1.5 Coil
The coil detects the intensity of the magnetic field that
is generated by the peripheral wire.

4.1.6 Tilt / Rollover / and Temperature
Sensors
These sensors are located on the main circuit board
inside of the electrical box.
The tilt sensor detects the angle of the slope on which
the robot is working. If this angle exceeds 30° (58%), an
alarm will be raised and the robot will stop moving.
The rollover sensor detects if the robot has been tipped
upside down, or whether someone is trying to start the
robot when it is upside down.
The temperature sensor measures the ambient
outdoor temperature and will prevent the robot from
operating if this temperature is too low. The minimum
temperature is set as an operating parameter.
4.1.7 Detectors
1)
Full Basket Detector – This flap is rotated upward
by the presence of balls in the basket. When this
basket is full, the robot will go to the drop pit to
unload the balls.
2)
Ball Counting Band – A pressure sensitive band
located on the underside of this component. As
the balls are ejected from between the collection
discs and hit this band, they are counted.
3)
Rotational Speed Detector – The rotational
speed of a marker on the roller is picked up by a
sensor on the chassis. If the speed is too low, the
roller may be blocked. The robot will try to
remove the blockage. If the blockage cannot be
removed, the robot will return to the charging
station and issue an alarm.
