It might be nice to try this model with a PC also... the obvious advantage
of the palm/wince/whatever handheld is that it would be mobile of course
(it'd be nice if the RCX had some sort of hardwire interface onboard - oh
well, an improvement for the next rev)... nevertheless, it would be
interesting to have the RCX change it's behavior based on a larger program
running on some other device; so for example in the typical PC setup you
could have something like:
1. code executing on the rcx
2. rcx informs pc of it's state periodically via the messaging functions
(through ir - pick your flavor of OS)
3. pc program evaluates input and either sends message data to rcx (change
behavior via change in data - eg, blackboard model) or sets up a *new*
program (from a set of programs or jit) and sends it to the rcx to be run
(thhis could cause processing delays though - not sure if the rcx can keep
chugging along while its receiving data, and you have timing issues for data
transfer/receipt queueing up to use the ir ports...)
...
...seems possible from the stuff I've seen in just the native (lego
provided) OS and the (lego provided) VB control... I'm sure variations on
the theme can be implemented in any of the othe environments that are
available as well....
