9) Following Light
Circuit:
• Light follower
• Brake mode
Sensors:
Point the side ones
approximately 30°
backwards and the
middle one about 45°
forwards.
The more you point the middle sensor upwards,
the closer varikabi will come the light above it.
If you hold your hand between the light and
varikabi, it tries to move back into the light.
varikabi moves toward
light from above it and
stops underneath.
It turns away from
shadows to move back
into the light.
10) Following Shadows
Circuit:
• Shadow follower
• Brake mode
Sensors:
Point the middle one
vertically upwards
and the side ones
approx. 60° upwards.
First, hold your hand over varikabi to stop it. Then,
move your hand slowly forward or to the side, so
that varikabi can follow it. Make sure you don't
have dark sleeves.
varikabi avoids light and
moves towards a shadow
over it (e.g., a hand).
It stops in the shadow or
follows it if the shadow
moves.
