It's not. This is a myth created by the CDC. Not an intentional myth, but an overhyping of research data which were found to be faulty. Using the CDC criterion Will Smith fit into the Obese category. An overzealous press trumpeted the story for a couple of months, and when the story became old the mistake was uncovered, only by then nobody was interested and the press didn't want to lose face.

(yes, I know not everyone likes Fox news, but the facts are right about the CDC)

The U.S. media will point out any problem in the U.S. first, and this information is broadcast all over the world. CNN, Fox, etc. will tell you about the health of U.S. citizens, but they will only infrequently tell you of similar trends in Europe or anywhere else. Not too many months back it was in the UK and European press that weight gain was as much, if not moreso, a problem in Europe than the U.S. I know because I visit every year. Two trends:

  1. The world as a whole is now richer than it ever has been. People are able to spend more money on anything including food. Snack foods and treats were rare when I was young, and just weren't as available as they are now.
  2. People are living longer due to new medical and drug treatments. The CDC and the WHO along with researchers the world over conquer problem after problem, until the #1 impediment to good health is now seen(or at least was for a couple of months) as bad diet and lack of excersize(spellcheck?). This is only the next domino to knock down, and so it gets the press. I wonder what the #1 cause of death will be when the average lifespan is 85?

Now, don't believe everything you read, and don't throw around the latest disinformation in a defamitory way just because you can't bother to look up the facts.

If you've got the bucks, just use a wheelchair undercarriage. Figure out how to interface an ordinary RC controller box, and you're done. ;-)

Good Luck! Rich

Does the bot need to be free standing? Can you put it on a track? If you are using the guide wire method you would wind up digging some kind of channel to bury it anyway. Another thought is to think of a similar methodology as a cable car, rather than mounting the locomotion onto the bot, mount it at the bots 'station'.

just a thought... material movement machinery has been around a long time, perhaps looking through a company that sells this type of equipment may spark some ideas...

Old age ?:-)

My father is 87 and I see signs that his body is simply wearing out :-(

Dean Burell -

Nehmo - A track would be fine; no steering would be necessary. But tracks are expensive and require installation. This bot should work in the common situation of a driveway leading the curb. The current state of technology is advanced enough so that the navigation can be provided by small a video camera, a computer, a steering servo, and some software.

For this first one, I'm pretty much settled on the chassis being built from the Harbor Freight cart

I don't know how to accomplish the steering and navigation yet.

I was thinking that this could be done surprisingly simple. Sounds like a line follower robot. Simply provide a line to the curb. Put an ultrasonic/IR sensor package to detect something/someone around so it won't bump into and another to not fall off the curb. Could be put on a timer so that it would follow the line to the curb at a certain time and when the trash is taken off (the weight is lightened) it would follow the line back. I don't think this would be all that technically challenging. Perhaps there are other issues that I am not thinking about but this would probably get you 80% there. But this is what I came up with off the top of my head.
