I say use both.  The HB is great at sensing and driving, but for
heavy-duty processing, use another processor.  Don't limit yourself to
8051 derivatives either.

ImageCraft sells a very nice HC11 C compiler.  You can check them out at
http://www.imagecraft.com.

wondering if I could get some opinions here.  A friend of mine and I are
going to build a robot, and we are trying to decide if we should go with
the HB, or make something else.  I know this is the HB list, so please
feel free to share your experienced opinions.

My friend is biased towards the 8051 derivatives.  He has already done
some stuff with the Dallas Semi chip called 'Speed it uP'  which is a
6mip (!) 8051 derivative.  I'm a game developer (not a hardware guy as
you can probably see already), so to me, lots of speed in the micro
sounds good since I could implement  complicated (AI, fuzzy, complicated
path-finding) routines for controlling the Bot, without worrying about
the thing bogging down.
The one compelling reason he gives for using the 6mip 8051 thing is that
he already has a nice C compiler that produces optimized code (besides
having a pretty windoze interface, etc.).  And of course he's familiar
with it already.

To me, the fact that you can buy a HandyBoard prebuilt sounds good.  But
the idea of Interactive-C sounds bad to me, since it's pcode, and
probably fairly slow (is it?  Has anyone tried to do complicated things
that IC can't keep up with?)  Is there any other 68hc11 C compilers out
there for a reasonable price?  I haven't seen any yet.

So what do you all think?  HandyBoard and InteractiveC, or 6mip 8051ish
thing with homegrown board?
Which do you think is easier, more expandable, more powerful?

Sorry this was a long post, and thanks for any advice you can offer,

Another followup, there is no "right" answer either. There is no perfect processor, the reality is, no one has the best experience to build the perfect processor. Don't not build something because there isn't a right answer. Build something, add to (...) (27 years ago, 23-Apr-97, to lugnet.robotics.handyboard)
