It is therefore not an official action, because the Guinness Book of Records would have to be there for that. The Railway Museum has tried that, but it costs a lot of money. The official record is set in Hong Kong. 255 robots drove there in succession. And then there is another record in Belgium, where lego robots drive behind each other. “Whether it succeeds or not, the day has already passed”, says a smiling Olivier van Beekum. Olivier is from the Leaphy Foundation, which supplied the robots in the form of a kit to the students. Those students then built and programmed the Leaphys themselves. “You can connect it in ten different ways and it will eventually do the same thing. That is a very big advantage in the classroom, but today it is a disadvantage because you want them all to do exactly the same.”
