During two intensive days, we built the self-driving truth proclaimers using toy excavators, megaphones, Arduinos, proximity sensors and excessive decoration materials as our basis. Three teams worked on three robots, not only soldering and hot glueing, but also theming their vehicles. This was achieved by creating audio messages in the form of mp3 files, and designing the visual looks of the wise vehicles.

One of the robots was a black hole, which chanted a message created by artificial intelligence, beyond comprehension. Contrary to its rough and apocalyptic looks, the second robot was sterile white and carried styrofoamy molecular structures. In accordance with its spherical structures, it was reciting the decimals of pi with synthesizer tunes. The third robot was totally different. It was a colorful punk robot packed with junk, shouting science quotes, sparing no swearwords. Niklas and me had also made one robot as an example for the workshop. It was, somewhat modestly, promoting the hydrogen atom.

The finished truth proclaimers were presented at the festival for more science lovers to enjoy.

Special thanks to Polytech Festival for inviting us to give the workshop, for the workshop participants who made amazing robots and for the festival volunteers who looked after them.
