This morning I saw this as I walked to my office. Nearby some young people explained to me that it was a robot sensor, that could be sent into areas that were unsafe for humans and would report on what was there, using a variety of sensors. Several branding markers on the robot indicated that this was a well-supported funded project.
I asked if they were PhD students. They laughed, and said that no, they were researchers (postdocs, I wonder?), but that they had an 'army of PhD students' working on the project. One of them added "Cheap labour", to general merriment.
