The limiting factor was Operator attention and issues with an environment. In a closed, mapped environment like a campus with minimal street crossings. The robot can make its way to the restaurant, get the delivery and make the delivery, with out operator input or attention… even if people block the robot, it can navigate around and interact. After a couple failed attempts, it alerts an operator and then manual action may occur. Some situations were a bit more complicated. I’ve had to navigate 4 robots, all at street crossings with different types of traffic. The safe thing to do is, take care of them one at a time, even if a couple robots miss the light. Once a crossing light changes and things look safe, we would just initiate the crossing. The robot can navigate on its own.
