Oric_dan, I will definitely check out those books! The first one especially looks useful.
In your first post, you said your weren't sure what to do with your robot. The nice thing about
the Mobile Robots book [besides cheap on used] is it describes a number of easy to program
projects, including light-following.
Both books describe the Subsumption robotics scheme invented by Rod Brooks from MIT back
in 1985 or so. If you use the state-machine approach described initially, it's easy to program the
robots without needing a multitasker, like Jones uses in later examples. The only real difference
between the 2 approaches is, with state-machines you have to do time-checks explicitly, while
with the multitasker you can use sleep() functions to produce timing pauses.
Using Subsumption, you can build a smart-appearing robot with a range of different behaviors
