The Lillebrø is a classic differential drive wanderer.
Behavior
Drives forward until some obstacle is detected. Then the Lillebrø makes a turn. If it gets to close to an obstacle the Lillebrø drives backward until it is enough far away. Then continues to wander.
The Making
First, there was a small Pringles package. This package almost landed in the thrash when I realized it is a perfect body for a Start Here kind of robot. Two motors got embedded and fitted almost perfect into this Pringles pack.
The package has a nice design but not for this rollerbot. So the package got covered by post-pack paper.
Out of an empty medicinal pack the robot's head got cut out.
The Software
TBD
Further Readings
NeoPixels. Power them with 5V and chain them together, tying the Data-Out pin of one to the Data-in of the previous one in the chain. If you're using an Arduino, you can control these LEDs with our wonderfully-written Neopixel library for Arduino.

Proximity Sensors. The Sharp GP2Y0A21YK is an Infrared proximity Sensor. It shines a beam of IR light from an LED, and measures the intensity of light that is bounced pack using a phototransistor.
