Quite a bit has happened since the last entry.

First, the robotics project finally has a name. Thanks to my wife, the robot has been christened Sophie 1.0.

I have also received the last few items on my parts list including the SMP20-2008- A stepper motors and a small Dell Pentium II laptop that will be used in some much later phase of the project.

The detailed design of the mechanical portion of the project as been completed. Now I just need to do some CAD work to be able to call the mechanical design finished and to have some pretty pictures to post online. (I think I'll scan and post my paper drawings too, just for the hell of it--whenever I get my webserver configured and give the Sophie 1.0 project a home page.)

The design of the electrical/motor portions of the system is just beginning.

Research and design continues on the electronic portions of the project. The circuitry to support the PIC18F8720 microcontroller is currently being designed as are the stepper motor drive circuits and the power supply circuits. My confusion over the Accelerometers has been cleared up thanks to the guys in the Kansas City Area Robotics Society.

I attended my first KCARS meeting on Saturday. It was great to hang out and talk with people who have the same obsessions that I have.

I have started psuedocoding the software that will run in the PIC18F8720 microcontroller. I'll post the psuedocode when its more or less done. (Oh yeah, I guess I really need to finish setting up my webserver!) Also, I haven't yet decided whether to code in C or assembler.
