FIWARE’s marketing team designed a [**six-page brochure (PDF)**](/download/micro-ROS_Brochure.pdf) and a 4-minute explainer video (see above) on micro-ROS. In addition, FIWARE organized the whole booth design and construction. Yet, most important, they attracted thousands of visitors by the most beautiful exhibit on the fair: a 12m² LEGO city illustrating different IoT use-cases with tiny sensors, displays, and actuators.

The micro-ROS display was next to this LEGO city. Juan Flores and Ralph Lange, who did the booth service for micro-ROS during the three-day event, had their hands full. From the micro-ROS team, Bosch and eProsima had prepared a demo on micro-ROS with a Kobuki platform and a drone. One the first day, this demo was shown more than a hundred times.

About half of the visitors had never heard of ROS before. The fact that ROS and micro-ROS come under very permissive open-source licenses was appreciated explicitly by most of them. A number of visitors had already worked with ROS 1 and were eager to learn more about ROS 2 and micro-ROS. Yet, there were even visitors with hands-on experience with the micro-ROS stack.
