Hi Kenneth,
I can't add to your list, but have had some experience with Lejos which I
recommend highly. You can find more about it at
http://www.lugnet.com/robotics
The latest version, (1.03 beta) which you can download from that site, has
more features and smaller footprint than the previous one. It has pretty
much made TinyVM obsolete. The strength of Lejos is that it uses Java so
you get all the benefits of an object language plus many useful Java
features such as threads, listeners, and interfaces. About the only useful
part of Java not implemented is garbage collection, so you must be careful
about creating new temporary objects. The objects that wrapper the
underlying ROM routines and hardware are well designed and AFAIK allow you
to do anything that can be done with the hardware. A nice debugging feature
is the display on the LCD when the program quits because of an error or
exception. You can also display the amount of free memory available. RCX 2
RCX communications is possible, but a generic networking protocol has not
part of Lejos.
Try it, you'll like it.
Roger Glassey.
