Variobot varikabo Instructions Manual page 30

1) Following Light Lines
Setting:
• Light follower
• Brake mode
Sensors:
Point the side ones
approximately parallel
downwards and the
middle one a little more
towards the ground.
Adjust the distance between the side sensors to
the line width. Experiment with the inclination of
the sensors so that varikabi comes to a standstill at
the end of the line.
varikabo moves along
light-colored lines (e.g.
over white paper strips on
a dark background).
varikabo stops at the end
of the line.
2) Following Dark Lines
Setting:
• Shadow follower
• Acceleration mode
Sensors:
Point all 3 parallel
forwards and approx.
45° downwards.
Experiment with the distance between the side
sensors and the inclination of the center sensor to
adjust the speed control as well as possible.
varikabo travels on dark
lines (e.g. black insulating
tape).
varikabo accelerates on
straights and brakes in
sharp curves.
