Whoever said yard work is drudgery hasn't met

Whoever said yard work is drudgery hasn't met the robot lawn mower. This amazing new creation literally takes all the work right out of yard work (or at Harmonic Drive Gears Suppliers least the mowing part).

This new mower, also called a ?robomower?, literally does the work for you. Think of those new-fangled (and very popular) robot vacuum cleaners and you have the right idea.

Automatic lawn mowers are available in a variety of sizes, so you can get the one best for your yard size. But generally, robot mowers are best for lawns up to one acre in size. Robomowers operate on batteries and charge within 24 hours, depending on the  brand and model.

The benefits of robot mowers are numerous. You don't have to push or ride a mower to get your lawn mowed, you don't have to deal with clippings, you free up some of your precious weekend time, and the mulch it creates is a healthy alternative to your lawn over fertilizer. Robomowers are also good for the environment ? they take no gas or oil and create no emissions.

There are two general designs of automatic lawn mowers. One looks essentially like a lawn mower without the handle. You use a remote control to drive it into the yard and it can run for about 2 hours, cutting the lawn for you while you just watch. The more advanced robot mower recharges in a recharging 'station? and senses when the charge is getting low. It will return itself to the charging station to recharge.

There are some advantages to the robot mower that should be pointed out, since in some ways, the machine can do a better job than man. For example, most automatic lawn mowers can sense rocks, sticks and debris and will automatically go around them. In addition, many robot mowers come with child lock protections and bumpers.

So if you want robots to keep out from some of your web pages, you can ask robots to ignore the web pages that you don't want indexed, and to do that you can place a robots.txt file on the local root server of your web site.

In example if you have a directory called e-books and you want to ask robots to keep out of it, your robots.txt file should read:

User-agent: * Disallow: e-books/

When you don't have enough control over your server to set up a robots.txt file, you can try adding a META tag to the head section of any HTML document.

In example, a tag like the following tells robots not to index and not to follow links on a particular page:

meta name="ROBOTS" content="NOINDEX, NOFOLLOW"

Support for the META tag among robots is not so frequent as the Robots Exclusion Protocol, but most of major web indexes currently support it.

If you want to keep the search engines out of your news postings, you can create an an "X-no-archive" line in of your postings' headers:

But although common news clients allow you to add an X-no-archive line to the headers of your news postings, some of them don't permit you to do so.

The problem is that most search engines assume that all information they find is public unless marked otherwise.

So be careful because though the robot and archive exclusion standards may help keep your material out of major search engines there are some others that respect no such rules.

If you're highly concerned about the privacy of your e-mail and Usenet postings, you must use some anonymous remailers and PGP. You can read about it here:

Even if you are not particularly concerned about privacy, remember that anything you write will be indexed and archived somewhere for eternity, so use the robots.txt file as much as you need it.
