Let's Make Robots!

Eggbot may not go further

Here's the first hardware run on the next project-just a big cheap egg platform. I was hoping to make this my first Propeller robot but I'm not sure if this is worthy of such an elegant processor.  Think I'll get better traction and balance out of those little black ducks with more weight over the center?  Such small wheels-I don't know if encoders are an option, and that one side is going about half the other. Right now the steel castor in the back weighs more than the rest of the platform combined.  Gotta come up with a good battery solution too.

.6" DIP and Breadboard

Edit-I found this video today (well Limor did.) http://youtu.be/n5LEEoskiaM Lots of work but he gets it done.

I have a handful of chips I use that fit that .6" DIP category still-The ISD 17xx and now the Parallax chips.  The thing is it kind of sucks putting them on a breadboard-you end up lopsided and don't usually have enough tie points on one side to work with, and most chip designers don't put all the "necessary" connections on one side.  Now there are pictures of a "collector's item" breadboard made for this type of package:

GOTO FAIL:The next time you feel bad about coding, refer to this.

I hope I'm not the only one who spotted this on Wired.com, but it's nice to know that even the biggest baddest a$$es in coding make mistakes.  This isn't one that would throw a compilation in xCode though-or even get noticed.

Do you see it?  Here's how Wired explains it:

Light Painting Wooden Robot Arm

The music sounds like the subliminal tracks I used when I was recovering from surgeries but that is one pretty arm.

Comprehensive AI vs. Intelligent Utility

We should take refuge in the fact that very crude systems can accomplish an awful lot. Elegant capabilities are nice, but often unnecessary. -George Devol, Inventer of the the Unimate Robotic Arm.

This piece may be a little deep for most hobby roboticists, but it will be of great interest to some.  If for example you're just interested in making small toys that run around your desktop following a line or avoiding obstacles then you can probably ignore it.

H Bridge Trivia

Sorry guys-constipation and the iPad have me pondering the imponderables again. Can anyone explain to me why there are or why there need to be four f*€k!ng ground pins on these DIPS? They all run to the same point-it's not like ins 1-4 get a separate ground.
