But if we use not just the current input, but the current input and the
last input, we now have 4 binary inputs to trigger behaviors with, which
means 2^4 or 16 different combinations. And they will give us that much
more information about the state of the environment to react to. They
could mean things like this:

Prev Cur
LR LR meaning
00 00 nothing happening
00 11 Hit wall straight on
01 01 Hit something on right
01 11 Hit wall at angle
11 11 stuck.

Buy why stop at just the last two sensory input values? We can use 3, or
4, or 1000. The more historic sensory data we record, and use to trigger
our output behaviors, the more complex, and the more "intelligent" our
behaviors can become.

I'm afraid I haven't got past bump switches 101, but my robots use a
very simple history gathering algorithm to recognise when they are
caught in a corner. Expressing the recent frequency of collisions as a
stress factor, the robot can respond to being caught in a corner by
panicking and executing a radical about turn. I don't offer this as an
example of machine intelligence, but as an illustration of the types
of information the machine can build up using the simplest of sensors.

I agree that the complexity of sensory input does not necessarily
limit intelligence. A hypothetical intelligent robot armed only with a
bump sensor and an ability to perform rudimentary odometry, placed in
a box with an obstacle which it is allowed to discover and memorise
could make some profound logical deductions about the universe if the
obstacle was subsequently removed. That's assuming the robot has the
kind of cognitive capability to make deductions. Is that the key
point? Cognition. Or would syllogism suffice?
