|SR-1 has behavior based AI with 4 personality layers:
Behavior based AI doesn't think or plan but reacts on the sense impressions from the surroundings. This is a simple and very efficient behavior based on simple animals. An ant walks around randomly until it finds food. When it returns to anthill it leaves a trace of scent that draws other ants.
When SR-1 is in one of the 4 main personality layers/modes it can shift temporary to another personality mode with lower priority level depending on the output value of PIR-sensor, CDS-Photo detector or Hall sensor. When output value of PIR-sensor, CDS-Photo detector or Hall sensor changes again SR-1 will return to the previous personality mode with higher priority level, until it has reached the previous main personality mode with highest priority level. E.g. SR-1 will always (regardless to main personality mode) get into alarm mode when it's getting dark in the room, sound alarm when motion is detected and return to previous mode when it's getting light. When SR-1 gets stuck it will backup, turn right and try driving forward again. The priority order of the personality modes is implemented in CPLD Project Board.
