Research output: Contribution to journalArticlepeer-review


The authors have developed an outdoor mobile robot that has the ability to cross roads at an intersection or pedestrian crossing fully autonomously while traveling along sidewalks in an urban environment. This gives the robot the capability to travel longer and complex routes as the robot is able to cross a road and continue with its path. The developed robot has the unique ability to autonomously approach and activate the pedestrian push button with a mechanical finger. We first briefly describe the overall operation of such a road crossing robot. The rest of this paper then discusses in detail how the robot can meticulously navigate to and activate the pedestrian push button with the on-board finger. The contribution of this work is that although there are robots existing that perform precision docking or button activation, this robot is one of the few that can perform such an action in a real world outdoor environment that is completely unmodified. We prove this by deploying the robot in a real world road-crossing and it was successfully able to engage the pedestrian push button.
