Ira, cool micro mouse!

If your doing experiments with compasses, take a look at the Philips part KMZ51, it is much smaller than the Densmore part, you can make a compass using 2 of them set at 90 degrees, it will require 2 A/D channels from your micro controller, and 2 digital out puts. I know the KMZ51 is a bit harder to get your hands on than the Densmore part, however, they are much much much smaller. Great for mirco bots.

Also, your proximiter sensor looks kinda big, take a look at the QRD1114, they are small enough to use a bunch of them on your micro bot, they can also be configured to perform line following. You can find them at www.digikey.com, part #QRD1114-ND. Let me know if you are interested in knowing how to configure these for line following.

This message is for Michale Keesling, I have been pondering the concept of a 3 legged robot since I saw the Destroyers in Star Wars, however, I am unable to conceptualize the gait required to make a 3 legged robot stable, have you solved this problem? Any ways, I was also unable to find your email address on your web site, could you send me and email so that we can talk about this? My email address is jwoods@roboshack.com.

Thanks for your time.

My goodness,

I received my long awaited parts to day. I'm sure every one is familiar with that scene from Ace Venture pet detective, where dude drop kicks, scrapes and smashes that package all the way to the dog napper's house. The box my parts came in looked like it was that very same box used in the movie. Not to mention it had been opened and re- sealed. Kinda makes me wonder what UPS is up to these days, are they using robot part sniffing gorillas?

Last week, I finally broke down and purchased the development tools for the Cyngal line of micro controllers. They are based on an 8051 core. I was pleasantly surprised. As it turned out, it is by far one of the best development environments I have seen in a micro controller. This processor sports bookoo I/O and 25 mips to boot. In July of this year they are releasing a 100 mips version! Can't wait :)_ It's a 3V part, which is well suited to battery-powered applications. The first thing I made using this new processor was a 32-channel servo controller, it was plenty fast enough to get full 8-bit resolution on all 32 servos!

If you're in the market for something with a bit more power and flexibility than a PIC, you can get all the information and order the parts as well from www.cygnal.com

I've been terribly sick these past few days, with one of the worst flu's I've had in years, last night in a feverous Nyquil induced comma I had an out of body experience, I traveled to a far away place high up on a mountain, where the secrets of the universe where passed on to me. The most important of which went something like this. ``All things dealing with humans eventually lead to something going in or out of an orifice''. Upon awakening, I realized that I may have suffered irreversible brain damage brought about by high fever and over indulgence of that store bought legalized hallucinogenic drug called Nyquil....................

My work allowed me to attend the Industrial Lab Automation show today in Palm Springs, CA. It was very exciting, there were many incredibly cool robots. Although these robots are very specialized in what they do, it was interesting to see how each company accomplished a similar task in a deferent way. I would have to say with out a doubt, the coolest robot was this standalone work cell, that processed and incubated cells so that you could go home on Friday, and when you return to work on Monday, you would have a complete library of cells ready to work with. I also saw a robot that could dig around in a group of cells, cut away a single cell, then pick it up and put it on a clean slide.

The construction of my PCB Mill\Engraver is complete. Now I can concentrate on the software to make this marvelous machine produce robots! Come and take a look at the new photos and let me know what ya think.

FINALLY!, the silly season is over!, now we can get back to work on our robot projects. Hope every one had a good holiday........................

Ok, I have complete about 90% of my PCB milling machine, about all that is left is the stepper motors, the drivers, and the tabletop. It's looking and working good. Come take a look.

Hehe, Jim... too funny, I've done the same thing, except, I don't care who's watching. Keeps them wondering..........
