Variobot varikabo Instructions Manual page 29

The four basic settings
You can remove the left and right sensors from the
LEDs and swap them with each other. This
determines whether varikabo moves towards dark
or light areas.
•
Sensor cable crossed: light follower
•
Sensor cable parallel: Shadow follower
For functions 10 and 12, the side sensors are
directed to the rear.
Use the selector switch to decide whether the
sensor signals are connected directly (=) or
reversed (×) to the transistors (T
(M /M ). This selects the acceleration or braking

mode.
•
Switch to "FAST (=)": varikabo accelerates
when a shadow falls on the middle sensor.
•
Switch to "STOP (×)": varikabo brakes when a
shadow falls on the middle sensor.
/T ) or the motors

Aligning the sensors
By pointing the three pivoting sensors downwards,
forwards or upwards, you can determine whether
varikabo perceives impressions on the ground, in
front of it or above it.
The brightness ratio between the side sensors
determines varikabo's direction of travel. The
brightness ratio between the center and side
sensors determines its speed.
On the following six pages, you will learn how to
set up each function. If varikabo does not
immediately work as expected, readjust the
orientation of the sensors.
Once you have familiarized yourself with the
various functions, the four diagrams at the end of
this section will help you to adjust them even
more quickly.
