Slashdot Mirror

siavash_of_stockholm asks: "I have a lot of spare time this so summer, so I've decided to be productive and make my own simple robot. It will come with some basic functions and it should move around without colliding or somehow avoid getting stuck in small areas and so on. I'd prefer to do this without using the popular Lego Mindstorm-kits and instead try to use a laptop and a controller card for the motors and a cheap webcam for vision. Has anyone in the Slashdot community made a similar project (on a tight student budget) and have some documentation of it they can share?"

Way back in October we solicited ideas for Christmas presents for geeks. This was done with Wired, and the results appear in the current issue (the lime-green colored one: unless you're blind, you can't miss it. You'll only be able to find the first copy, tho). The authors' money will be a nice Christmas present to the EFF. Thanks go to Paul, who did all the really hard work compiling the final list from all your ideas. Now read on to see the list.

1. PlayStation2 - Sony list price $299.99; winning bids on eBay $550-1,375. Supplies are extremely limited. CowboyNeal has been waiting for his for months.
2. Beowulf parallel computing cluster; 3 nodes for $1,305.95. A build-your-own supercomputer: three bargain PCs with Ethernet cards ($415 each), one four-port network hub ($16), and one Building Linux Clusters book from O'Reilly and Associates ($44.95), which includes Red Hat Linux and cluster software on CD. Perfect for trolls who lack a single iota of creativity, or that guy you know who always wants to simulate weather patterns.
3. Car MP3 player - empeg $1,199 (and it even runs Linux, if you're into that sort of thing).
4. IC-R3 handheld wideband radio/TV receiver - Icom America $599. 500-kHz to 2.4-GHz spybox tunes in to everything but cell phones. Voyeurism isn't just for breakfast anymore.
5. iPAQ H3600 Linux-compatible handheld - Compaq $499, but good luck finding one. Apparently there is quite the shortage.
6. Nomad Jukebox - Creative Labs $499. Give this, instead of a CD player, to your loved one in the Napster T-shirt ...
7. Matrix- and Blade Runner-styled trench coats - TrenchCo. $375-482.
8. CD-RW drive, $150-350. No drive fits all machines, so verify compatibility before you buy. Many popular drives have to be back-ordered, but others are always in stock.
9. Voodoo5 5500 AGP or PCI graphics card - 3dfx Interactive $299.99. Better graphics than PlayStation2, on your computer instead of your TV.
10. Klein Bottle - Acme $25-250. Designed by astronomer-author Cliff Stoll.
11. MindStorms - Lego MindStorms $50-200. Classic Lego building blocks, updated with motors and microchips.
12. GlobalMap 100 GPS - Lowrance Electronics $199.95. I get lost in my backyard. I wonder if this thing has a map of my back yard.
13. TiNi Pocket PowerPlier - SOG Specialty Knives and Tools $84.95. Just keep those fingers free of extra holes.
14. Broadband Internet access $39-50 per month (plus installation charges). Check for availability in your area. Consider moving. I know I do almost every day.
15. Interactive Yoda - Tiger $39.99. A Jedi craves not these things. But if he gets one for Christmas, that's different.
16. Non-computer games - Looney Labs $5-35. Card games that modify their own rules, and board games for the brainy.
17. EverQuest - Sony $29.95 (plus $9.89 monthly service fee). Addictive multiplayer game lets you collaborate with others on the Net. Suitable even for a 200-MHz PC with a 28K connection. And the graphics look like ass. But I have many friends who've lost countless productive hours all for the lucrative reward of being able to take a bear by yourself in a virtual world.
18. Tech-book gift certificate - Fatbrain.com $10-25. Let her choose her own robot-building manual.
19. Klein Bottle knit cap or Mobius ear band - Math Hatter $12-22.
20. Penguin Caffeinated Peppermints - ifive brands $12 (four-pack). Essential fuel for all-night hacking: sugar and caffeine wrapped in a handy breath mint. I'll never forget the time Trae ate a whole tin at ALS and traveled forward through time.

Cy Guy writes "Lego has announced that they are buying Paul Allen's Zowie Intertainment. Zowie's toys let you animate your own cartoons by tracking the movement of character pieces on a play set connected to your PC. Lego plans to integrate the Zowie technology into its popular Mindstorms products. No word as to whether Allen was selling his toys because of the sudden devaluation of his MS stock. "

rhempel wrote to us about an interesting LEGO Mindstorms programming tool he's created called pbForth. Click below to learn more about it - but let's talk about Mindstorms programming in general. What else is everyone using? What's the coolest thing you've done with them?

I've developed pbForth, a port of a rather archaic programming language, for the LEGO Mindstorms brick. The cool thing about it is that with a dumb terminal emulator that does ASCII uploads and can handle XMODEM (checksum) transfers, you can compile applications right on the brick! Yes, on the brick! When you are done, you blast S records back to your PC using XMODEM and then you can reload the app anytime using one of the standard firmware uploaders.

Check out pbForth for LEGO Mindstorms

pbForth got a whole chapter in the O'Reilly book, and it is getting more and more momentum as replacement firmware that busts the 32 variable barrier, and allows total cross-platform development without screwing around with building ecgs.

OK, I'm biased - I wrote it - but I think it's cool. Maybe some of you LEGO gearheads out there would like to try programming in something other than the native tongue. Learning Forth can make you a better C programmer. No, I'm not a Forth evangelist - I write embedded systems in C all day long.

Quite a number of you out there are into Lego Mindstorms, as evidenced by the number of book reviews that have been sent my way. Below are a couple of reviews, one from Kurt DeMaagd and the other from Will Ware. Click below to get their take on the O'Reilly book The Unofficial Guide to Lego Mindstorms Robots. The Unofficial Guide to Lego Mindstorms Robots author Jonathan B.

Last year, Lego released their Mindstorms Robotics Invention System. Using this, children and adults can build simple robots whose behavior can be programmed. The Mindstorms system is a major contender for Coolest Toy on the Planet.

The system contains a RCX programmable brick containing an H8/300 microcontroller, some pushbuttons, a little LCD display, and connectors for motors and sensors (light and physical contact). The user writes a program using a graphical programming language on his Windows box, and downloads it to the RCX via infrared.

Not surprisingly, substantial reverse engineering (1, 2) has been done by hobbyists, and it is possible to develop Mindstorms programs on a Linux box and to download the RCX brick from Linux.

Now O'Reilly has joined the Mindstorms fray, with a book full of fun and useful information about how to build and program Mindstorms robots. The book describes four different robots: Hank is a bumper car robot, Trusty uses light sensors to follow a line along the floor, Minerva has a movable arm, and two identical robots play a game called RoboTag. Along the way, the author discusses the physics and mechanics of robots, programming issues, and the available development environments for Mindstorms.

What's Good? There are detailed building instructions for each of the robots, showing photos at various stages of construction. The designs are simple and appear mechanically sound. There are discussion of the physics and mechanics of tank treads, steering, gears, and other things.

The book's chapters sequentially step through several different software development environments. The first chapter starts with the Windows-based RIS environment that comes on the Mindstorms CDROM. Later chapters give programming examples for NQC (Not Quite C), pbFORTH, Visual Basic, and the legOS operating system, which uses an EGCS cross-compiler to target the H8/300. There are more development platforms available, but these give a good sense of what's possible in Mindstorms programming.

The book has dozens of useful URLs, for both official Mindstorm sites and unofficial hobbyist sites. I particularly liked the fact that the author was aware of some of the recent research in robotics. For instance there is some discussion of Rodney Brooks' subsumption architecture, which is used for the RoboTag robots.

Later chapters of the book often expand on designs from earlier chapters, building more sophistocated robots in an accessible, incremental fashion. For the more adventurous hobbyist, the final chapter talks about building your own sensors and actuators, and how to connect them to the RCX.

What's Bad? Some of the photos are too dark and lack contrast. It would also have been nice if the photography had been in color, but black-and-white photos kept the book more affordable.

This book is for the casual weekend robot-building tinkerer, and it never promised to discuss real-time embedded issues in depth. Still, a few topics might have merited at least brief mention. Systems with real-time multitasking must frequently arrange for synchronization and communication between tasks, using mutexes and mailboxes and the like, which brings the possibility of deadlocked processes. Another danger is that an aggressively efficient compiler will sometimes optimize away reads and writes to hardware registers. The fix is to declare such registers with the volatile keyword.

Review by Kurt DeMaagd

While Lego Mindstorms were officially released for a teenage crowd, they have become popular with a wide variety of technically competent people in many age groups. This widespread fascination has opened up a whole new world of opportunities for using Mindstorms. At the same time, the documentation and tutorial included with the Lego kits provide very little information about how to get the most out of the sets. This book fills the void by providing several start-to-finish robot designs, software to run them, and a wealth of other tips and tricks.

After a brief introduction to robotics and how Legos fit in, the author discusses the basics of using Mindstorms to create them. Both chapters present a problem, provide step by step building instructions, provide the necessary information to program the solution, and finally go into greater detail about the Lego features used to solve the particular problem.

While the chapters did an excellent job of presenting this information in general, they fell victim to a problem that would plague the entire book: some of the building diagrams were nigh unto unreadable. Attempting to build a robot based on fuzzy black and white photographs can be quite a chore. Fortunately, none of the robots were so complex that they robots were completely unbuildable.

The first few chapters presented robots programmed with the default RIS programming environment. In chapter four and following, he shows how to program using languages such as Not Quite C, Forth, Sprit.ocx for Visual Basic--or optionally Visual C++ or another ActiveX-aware language--and legOS. Since much of these sections was documenting API's, it was certainly not the most exciting read, but it does provide concise, easily to reference documentation.

Not Quite C, as the name implies, is a C-like language that can be used to program Mindstorms robots. It overcomes many of the limitations of the default RIS programming environment, most notably the lack of variables. One of its biggest advantages is that it does not require the user to install a new version of the firmware on their RCX unit. In general, it provides an excellent balance between power and usability.

The remaining three means of programming presented in the book are fairly mediocre options. PbForth requires the user to download a new firmware version, and the language itself is very archaic in modern software development terms. Using Sprit.ocx is a viable option for people used to programming in Visual Basic or Visual C++, but the control structures are very clunky and non-intuitive. legOS, while it is probably the most powerful option, takes a significant amount of time to set up and develop applications with.

Two of the projects referenced while discussing the various programming languages were particularly interesting, both of which outlined infrared communication. The first program creates a simple remote control for controlling a robot via the IR port on the RCX. The other example, perhaps the most interesting in the book, was creating two robots who played tag with each other. These two robots also communicated with each other via their IR ports.

The last chapter, targetted toward the hard core Mindstorms users outlined how to create additional sensors for Mindstorms. It sketched out such possibilities as a passive light sensor, a Hall effect sensor (magnetic fields), and a touch multiplexor (allowing you to have more touch sensors than normally allowed on the RCS unit).

In general, the book provides a vast array building and programming tips, tricks, and methods. He gives basic information for the person who is just starting, and introduces the advanced user to the vast network of people and product that have made Mindstorms far more than a child's toy.

Sit back and get jiggy with tonights Quickies: First up, jamiemccarthy sent us a Magic 8-Ball that claims to be operated by Legos. And if you're into those remote control legos, Paddy noted that there is new stuff on the lego website. Todays stranges item comes from Chris Henesy who sent us official NASA procedure for Viking Raids. Michael Van Vertloo sent us linkage to a webcam from the 6th floor of the Texas School Book Depositoryso you conspiracy theorists can keep an eye on it. Bogatyr noted that there now is actually a website selling stuff from the matrix. No, not the minigun, but sunglasses and stuff. tj2sent us linkage to an interview where George Lucas blaims the internet for Jar Jar sucking so badly. Mike sent us a page that tracks Strange things sold on ebay. Finally, markhb sent us a Washington Post profile of Marc Andreeson where he talks about assorted things, and even plugs Slashdot as one of his favorite sites (thanks Marc!) And finally, to bookend this Fresh block of quickies, harb sent us lyrics to the classic (cough) Will Smith Song "Men in Black" for Linux geeks.

When I put out my call for Geek Christmas Gift ideas, I had no idea what I was in for. But after the storm of email that followed was washed away, I was left with a list of toys that any geek would be excited to give or get this year for whatever holiday it is you celebrate this time of year. Hit the link below and read the list if you're curious. Random Stuff There were a few things that were suggested, that, well, I bet Santa won't come through for them. Hemos asks for Nanites. Thats all he wants. Nanites. Somebody smack him. Nima Negahban says "I would like the beowolf cluster avalon for christmas, dont worry about it fitting it under the tree. " david yates wrote in and simply said "Half naked Princess Leia ,as Jabba's prisoner, action figure." I'm sure his mother is proud. He can have the Action Figure, I want 1976 Carrie Fisher. Games Everyone and their brother wrote in to say that Nintendo 64's and Playstations are great. And the game of choice is definitely Zelda 64. I second that motion. I suggested it to my dad as a Christmas Present. Terrible idea- now I gotta wait until xmas to find out if he got it, and if he *didn't* I gotta buy in on Dec 26. Hard as hell to find. Folks suggested other things like the original Kings Quest or Leisure Suit Larry. Prince of Persia. Commander Keen. Ultima. All those games that aren't around any more, but with their original packaging. Finding a 5.25" drive to play them with might be a tad tricky tho. Clothing It's a well known fact that its better to be clothed at least part of the time. And no self respecting geek should be without a vast array of appropriately political t-shirts to pad out your closet full of suits, jackets, and ties (cough). Daniel suggested checking out the Free BSD Mall for BSD clothing. Jonathan Moore suggested the ever popular KMFMS t-shirts for your local microsoft hater. If thats a bit to exotic for you, how about the classic that Doug Boettcher sent us: the Hack Naked shirt. Since we're mentioning all these t-shirts, we ought to mention that CopyLeft has several shirts including my Don't Fear the Penguins ones, and Slashdot ones too. Software Several folks wrote in to say that they were buying Linux CDs from any of the various places that sell them, and giving them away to the needy. I tend towards Linux Central, and in addition to them Cheap Bytes OpenBsd.org and The Linux Mall were all suggested as places where you can buy the stuff we like. Hardware By far the largest catagory for gift ideas was of course Hardware:The Gift that Costs to much. Of course, anyone would want a a Palm III- it's hard to think of a better stocking stuffer. And besides, they're practically money in the bank now that you can use them to collect automobiles of the rich and famous. But if you've already got a Pilot, James A. Hillyerd suggests a GoType keyboard as the perfect accessory. If the pilot isn't your bag, but you want to read on the road, Mahlen Morris suggested A Rocket E-Book which is basically a tablet computer that is designed to replace books You can get them here. And apparently they have some sort of deal with Barnes & Nobles so you can get content to read on it. They're pretty sweet looking- someday we'll have a wireless version with net access, then we can forget paper. But for now, this'll do.

Have trouble remembering passwords? Digital Persona sells sweet hardware that that you can use to do finger print identification. Suggested by Andrew Lepisto. The pdQ was suggested by Adam D. McKenna. Its a cel phone with an integrated Pilot. Another fairly common suggestion for geek gifts was cel service from your local provider, and a cel modem for the laptop equipped gift getter. Sean McPherson suggested a Kodak DC210+ digital camera. Saves big bucks on film, and is supposed to be supported by SANE. I'm actually planning on getting a Digital Camera before the upcoming string of conferences, and I'll probably look at this one (unless Santa already has one in his bag for me, although at $400 a pop, I highly doubt it) Steven McDonald suggests that we look at DVD RAM Drives as a new huge backup device for storing your MP3s and Porn. Oh, and legit data too.

Mike Miller sent us several suggestions including the Happy Hacking Keyboard. I played with one at ALS- they're not bad. Just as cool are the new Color Gamesboys. I suppose tetris wouldn't be vastly improved by color, but its still pretty sweet. For those with a hugeass budget, How about your very own Alpha Cluster? Obviously Jakob is a lot more hopeful for Saint Nick than I am this year *grin*. How about a vt320 Terminal? Daniel Morrison suggested it, and I think it sounds pretty cool. I had a terminal attached to one of my Linux boxes for awhile. I Let it tail log files and stuff. Kinda fun for reading documentation and stuff too. Can't afford a Multi-Head X-Server, video card, and spare monitor anyway. Plus you can run them into another room and check your email from your kitchen/dining room/bathroom.

Matthew J. Allen sent us a pricey one, but its oh so sweet: Remember those Huge Flat LCD Screens from SGI? I sure do. I wake up after erotic dreams about them. (SUBLIMINAL MESSAGE:Hey SGI: Give Rob one of those things for banner ads. You've got a spare one just sitting around, right?). Matthew also suggested an Iomega Clik Drive if you're on a more reasonable budget. Those things do look pretty sweet. Do cables piss you off? How about the gift of a tangle free workspace? Scott Donovan sent us a link to Cordless Mice and Keyboards from Logitech that will free you up for spinning on your swivel chair really fast until you fall over from getting dizzy instead of getting tangled up in your keyboard cable.

Toys By far the single most suggested toy of all was the Lego Mindstorms. The robotic legos are quite possibly the coolest toy in the history of toys. They aren't cheap, but they are oh so sweet. Else you could consider X-Files Action Figures suggested by E. Waugh. Home Entertainment and Audio Gear The Panasonic Portable DVD Theater was sent in by Joel Telling. Its a tiny portable DVD player obviously designed to make me froth at the mouth like a rabid dog. Several folks wrote in to suggest something I would like, but I wouldn't want to froth on. The Empeg Car CD Player. We've mentioned this before, and although they won't be ready for christmas, they are pretty amazing. 2.1 gigs of MP3s in a car stereo. They need a 9 gig version mounted in a home stereo component too.

Jon Jones (is that a real name? *grin*) wrote in to send a link to ADB I/O which you can use to automate your home for the ultimate in comfort and/or laziness. For the true audio junkie, how about the THX Speakers sent in by Chad R. Henry. Sure, they cost more than my car, but I bet they sound amazing. If you're on a more modest budget Cambridge SoundWorks has some slightly more reasonably priced speakers that I'm told sound awesome. Andrew Hobgood suggests checking out Panasonic SJ-MJ70 MiniDisc Player (portable). Pretty sweet if you aren't willing to chance it on the Diamond Rio (which was also one of the most common suggestions). Frankly any geek should be excited to get either. Rob Sheehy pointed out that Philips has 42 inch widescreen flat TVs that you could hang on your wall if you happen to be rich and wanna watch letterbox movies. This one has a VGA input too.

Random Terry A. Braun suggests that geeks need to get into making our own beer. Sounds like a great idea to me, although I tend to screw up toast. But if you're man enough to try it, you can get Your Own Grain Mill. Alan Mathews wrote in to suggest a A dilbert M&M dispensor McPhee's has some strange stuff, including a Punching Nun suggested by Glen Lipka Tom Berger suggested A VI Command Set Mug STriker RedWolf sent us a link to a chocolate bar shaped like a Pentuim II Chip.

Jason Grundy suggests the $6 card game Kill Dr. Lucky and a Card both from the aptly titled Cheapass.com. Rob Pelkey sent in a pair of gift ideas that are a world apart. The first is An Authentic Moon Rock and the second is a Jesse Ventura T-Shirt or Bumper Sticker. One is probably worth a little more than the other. The concept kitchen has this wierd Finger Stylus Thingee that you can use instead of a pen for some pen machines. Kinda wacky. Sent to us by Wyatt Earp.

Justin Higgins suggests that geeks should all own a copy of the Star Wars Radio Drama. Sure, it costs almost a hundred bucks, but at 15 CDs, it balances out to almost be a bargain. They ought to package it on 1 CD full of MP3s, throw a copy of the script on the disc and sell it for $20. I'd never heard of the Leatherman Wave before, but several folks emailed me to say they are cool. And then I noticed that they were actually advertising here. Shows how much attention I pay to who advertises on my own site I guess. But still several people raved about them, claiming that they're ideal for mucking around inside computer cases with. And Traci Earl sent a link to a site that makes nice Leather Cases for them.

Do you think stuffed animals are stupid? Well how about a Stuffed Plush Space Shuttle? Dave Brunberg sent us that gem. Stirling Westrup sent in a link to something called the Hoberman Sphere which basically is a crazily designed sphere thingee that expands from 9.5" to 30". Crazy looking. If you're looking for something caffienated that you can put in your mouth, several folks reminded us about caffienated penguin mints.

Wrap Up Well this was fun guys. Spending hours looking at crazy things that I can't afford has convinced me to take up cracking banks as an evening hobby. But what is quite obvious is that 1998 is a good year to be a geek. And maybe in 1999 Hemos can have his nanites. Nah.

And lastly, with all the commercial hub bub that tends to go on during this season, don't forget the true meaning of Christmas: Ham.

Thomas Charron wrote in to tell us that Lego Mindstorm (computer controlled lego based robotics) is now accepting applications for Beta Testers. You get a free set, but I suspect a Linux port might be a ways off yet :) Regardless, super cool.
