We were planning a technical challenge named "Tsukuba Challenge" last November in Tsukuba city. It is a part of the Real World Robot Challenge which is organized by robotic researchers to realize actual autonomous intelligent robots in our daily life. In the Tsukuba Challenge, robots are required to run autonomously and safely 1 km on a city promenade where people are daily walking. It is perfect Real World not specified places for robots such as laboratories, robot fields, and etc. This is the first trial with the actual world in Japan. In this paper the "Tsukuba Challenge" is briefly in produced with historical background of "Micro Mouse Contest"
