Because it never fixed it to begin with. Just because the light stayed out for a couple of days does not mean that it ever fixed. The computer has to see the problem occur through several drive cycles consequtively before it sets a code and turns on the light. This can take several days. My guess is that you have something else wrong with the EGR system that is causing the computer to see little or no activity at the DPFE sensor whenever it commands the EGR on. And it is probably NOT the EGR valve. Ford EGR valves seldom fail. There is one other possibility that you installed the DPFE backward. I would pull it off, and make sure the small diameter neck on the sensor is one the small diamter hose and the big diameter neck is on the big diameter hose. Otherwise, you probably have something causing little or no flow in the EGR system such as an EGR control malfunction, or a stopped up EGR passage in the intake manifold area.

What sensors does the robot have?

The sensors that an engineer puts on a robot are entirely dependent upon the functions that the engineer perceives that the the robot will be called upon to perform. Some, but not all, of the sensors may be: proximity sensors, pressure sensors, light sensors, magnetic sensors, a camera, temperature sensors, accelerometer, speed sensor... The question isn't, "what sensors does a robot have", but rather, "what sensors does the engineer think that the robot should have?"
