CrowdBot is a European Union Horizon 2020 (EU H2020) project for research and innovation in the area of Information and Communication Technologies (ICT), and funded by the European Commission for the period of January 2018─June 2021. The official name of the project is “Safe Navigation of Robots in Dense Human Crowds”, which is also the focus area of our research activities. The name “CrowdBot” is an amalgam of human “crowd” and machine “bot.” We also lovingly refer to any of our three robots as a CrowdBot. In particular UCL's robot is a smart wheelchair prototype.
