What kind of signal does the sensor provide? If it's a digital input, consider using a counter to capture the occurrence. The FPGA will detect the signal as quickly as it can do anything, and the robot code can watch for the counter to change value on whatever schedule is appropriate for responding to the signal.
I would say that you are not an engineer until you've both obtained the aforementioned peice of paper AND done something with your tumescent engineers forebrain. - phrontist [more]
