Startup Procedure
First point the middle sensor vertically upwards.
Swap the right sensor with the left sensor and
point them about 45° to the side. Test varikabo on
a smooth and light-colored floor.
When you now switch on varikabo, it moves
towards light and avoids objects. If you hold your
hand over the middle sensor, varikabo moves
quickly or stops.
varikabo compares the brightness via its three
sensors. Depending on the orientation of the
sensors, it detects the light conditions on the
ground, ahead, or above itself.
Unlike other robots, varikabo doesn't need to emit
infrared light to detect lines or objects, for
example. This simplifies the circuit and reduces
power consumption. Since varikabo responds to
the differences in brightness, however, it is
important to pay attention to the type of lighting
in the room.
Notes on Lighting
To ensure varikabo's sensors aren't blinded by the
light sources, make sure varikabi is well positioned
in relation to lamps and windows.
Operate varikabo preferably under a distant
●
light source or beneath a window on the floor.
If light comes from the sides, varikabo might
follow this light or its own shadow instead of
moving towards the desired goal.
When using LEDs or fluorescent light bulbs,
●
ensure the lighting is bright enough for
varikabo to detect it.
The light from LEDs and fluorescent light bulbs
has a low red component and isn't easy for
varikabo's sensors to detect.
Make sure the ground does not reflect light.
