Holger from Fablab Düsseldorf writes in about a small robot they prototyped with Arduino Uno, helping them raise some funds for their local space:
We created the idea in our non-commerical FabLab in Düsseldorf, Germany to create a small robot, who makes our vistors and guests aware of placing a small money donation. This robot was required to be transportable, robust and to draw as much attention as possible.
Thus, we included LED-Stripes, servos, sensors and sound to the project. Packed in a very old german vacuum cleaner. The work took about 1 year to construct, print and integrate all 3D-printed parts, wiring and software development with the Arduino Uno. But software development was the minor part, although parallel processing on the Arduino in order to run every component simultaneously required a small trick.
