The objective of this article is to present a specific urban challenge proposed by European cities in ECHORD++ project that can be the starter point of new innovative public procurements. The project that was selected by the project leading team has been a robotic solution for monitoring the sewage system of a European city. Cities are prepared and the Research and Technological Development (RTD) consortia are waiting for real opportunities. The take-off of the robotic technology could be possible: from Lab to Market addressing real urban needs of citizens and cities. The proposals obtained in ECHORD++ could be followed by other cities.
