I am still working on the various modules for CIRCE-II; however, even though I have the JSTamp development system the lack of functional hardware is preventing me from developing the software for this system.
I recently decided to purchase the BOE-BOT parts from Parallax along with their new Javalin Stamp Starter Kit. I received the kits yesterday. I've already started developing the low level motor control classes. While the low level hardware control will certainly be different from CIRCE-II this environment allows me to start developing all but the upper level AI code.
Using this approach I can alternate between HW/SW/Sensors. In addition the need to port the software between two different embedded java environments should make for a better software design.
