Fuzzification Submodule: As the FLC module catches
the data measured by the infrared sensors, the data have to be
transmitted into the input of the FLC module. The architecture
of the fuzzification submodule is illustrated in Fig. 10(d). We
design a judgment circuit to determine which statuses the input
variables of the FLC scheme will be. The “Choice” signal from
the behavior selection control module is used to decide that the
CLMR should go forward or move backward. When “Choice”
signal is low, the CLMR will go forward and use the forward
FWFC and, on the contrary, the CLMR will move backward
and adopt the backward FWFC.
