New Evidence - The Nazca Lines were made by robots!

Bill Loguidice's picture

Yes, you read that right, the famous Nazca Lines in Peru were made by robots and I have proof! After unleashing...
...my newly purchased, heavily discounted and now last generation Roomba from iRobot (click here for the newly released model), I made the startling discovery, as evidenced by the photo below from its first cleaning session:

Yes, of course I'm being rather silly, but I am quite happy with the purchase (it was about $100 from Buy.com, and it came with self-docking station, remote and one virtual wall) as it actually does a nice job cleaning, making the rug nice and fluffy. My wife Christina was so impressed she even inquired about the Scooba, which mops floors. Sadly, right now, it's out of our price range. Nevertheless, the iRobot company really nailed what practical home robotics are all about (and of course many hobbyists use the excellent Roomba platform for their own creations).

The virtual wall, which stops the vacuum from crossing its beam, is shown to the lower right.

HERO JR RT-1: What is supposed to be coming...HERO JR RT-1: What is supposed to be coming...On a related note, I got a good deal from a gentleman on a Hero JR robot, which I always wanted. When it comes, I'll be sure to post about it (it will need some TLC, but it already has a tremendous base). Here is the seller's description, unedited:

"
I have gone through this robot thoroughly, repaired, and then tested every function to verify its operation. I just do not have the room here for my other projects.

This Jr has been reworked for improved performance; Steering drive has been moved out a bolt hole distance and provides best moble performance from expermenting with another Jr first to get it perfect. Also provides that needed stable platform.

Wheel counter disk has been properly mounted along with the troubled photo senser plug that has been wired up the side to proper header pins. No more loose plug !

Motor bushings treated with milatary gyro spray and synthetic lubed polished gear boxes, Smooth! Turned wheels for extra performance as drive wheel has been turned close to over a cc smaller dia. providing proper slower heating of drive fett along with other needed details.

A must have CPU mini fan added to hot side of boards along with foam semi ducting blocks in hood keeps the vibes down from Jrs large speech speaker as the speaker has a grill made on it for improved sound along with hood grill vains having thin filter foam to absorb the vibes and keeps dust out.

Other detailed work has been done too. Body parts have there stunds intacted except one at bottom of body panel, yet panels fit tight that had pin fittings loosen up for easy pulling and installing, also prevent breaking.

Hero Jr could use go over and one of the 2 speech ICs could use replacement or stacked old one, that there is a energy sound before speech turns off. This is common with the speach yet this Jr works fine.

Jr says he has 24576 bytes of access memory

Here are the hardware upgrades and options that I have installed:

Upgraded to 24K RAM - This is the most memory that can be installed in these robots.

- Infrared motion detector on head range about 35' long x 20' wide.

RTA-1-3 - RS232 interface allows use of the BASIC cartridge.

I have a 12VRoboscout battery in it that needs replaced with new 7Ah, yet battery is workable.

RTA-1-5 - Cartridge Adapter - permits use of plug in cartridges.

Cartridge – RTC-1-11 Musical Chairs with Acey-Ducey and Robot mind reader

Power Charger - Original charger

The manuals and books are:

Hero Jr. Robot Assembly Guide - Original

Hero Jr. Owners maniul - Original

Skids - Original
"

I ALWAYS wanted one of these Heathkit robots after seeing them in magazines as a kid and getting to see one in person in middle school during a demonstration. Now, I get to be a proud owner of an albeit low end, but still amazingly functional model. I also put a feeler out on one of the multi-carts, which contains every cartridge released in one cartridge. I hope to also get the classic computer interface so I can program directly and the cassette interface wouldn't be so bad either, but both of those are longshots (it will be hard enough finding compatible batteries and seeing if there's an issue with the speech synthesis). In any case, I have plenty of systems with keypad entry, so I should do well enough with that and there may be other workarounds I can try (goodness knows I have plenty of cables of various types lying around and what-have-you).

More Roomba and Scooba

Well, the Roomba definitely does hardwood floors. In fact, it does all surface types. Of course, it is just a vacuum, meaning suction (dust bunnies, etc.), so yeah, the Scooba is designed for actual mopping and it is rather expensive for what it does. It also uses some Clorox solution, so I'm not sure how that works. Probably when the Scooba goes to the bargain bin like the model of Roomba I have, I'll take the plunge. Any more than $100 or so and I wouldn't bother, myself.

iRobot Roomba for $79.99 with free shipping

As you know, I love mine, and Buy.com has a great deal on a refurb for $79.99. It's exactly the same as what I have, except it's missing the dock and remote, the latter of which being pretty much useless in my opinion. So, other than having to plug the vacuum in yourself to charge it rather than it automatically going back to its docking station, it's a solid deal: http://www.buy.com/retail/product.asp?sku=203159876&adid=17654&dcaid=17653
