Yes, as in all those letters you'd get home from school (when I was at a co-educational school) which mentioned the phrase son/daughter about five times in the letter. That was the 80s though - I'm sure these days you could link it to the gender field of a student database and print out the correct one. It'd be a bit more complicated than a mail merge though.

I met a Dutch girl with inflatable shoes last week, phoned her up to arrange a date but unfortunately she'd popped her clogs.

Two Eskimos sitting in a kayak were chilly; but when they lit a fire in the craft, it sank, proving once and for all that you can't have your kayak and heat it.

So I said "Do you want a game of Darts?", he said "OK then", I said "Nearest to bull starts". He said "Baa", I said "Moo", he said "You're closest".

You see I'm against hunting, in fact I'm a hunt saboteur. I go out the night before and shoot the fox.

The other day I sent my girlfriend a huge pile of snow. I rang her up, I said "Did you get my drift?".

So I went down the local supermarket, I said "I want to make a complaint, this vinegar's got lumps in it", he said "Those are pickled onions".

I saw this bloke chatting up a cheetah, I thought "he's trying to pull a fast one".

So I said to this train driver "I want to go to Paris". He said "Eurostar?". I said "I've been on telly but I'm no Dean Martin".

So I said to the Gym instructor "Can you teach me to do the splits?". He said "How flexible are you?". I said "I can't make Tuesdays".

But I'll tell you what I love doing more than anything: trying to pack myself in a small suitcase. I can hardly contain myself.

So I met this gangster who pulls up the back of people's pants, it was Wedgie Kray.

So I went to the Chinese restaurant and this duck came up to me with a red rose and says "Your eyes sparkle like diamonds". I said "Waiter, I asked for a-ROMATIC duck".

But I'm in great mood tonight because the other day I entered a competition and I won a years supply of Marmite......... one jar.

So this bloke says to me, "Can I come in your house and talk about your carpets?". I thought "That's all I need, a Je-hoover's witness".

You see my next door neighbour worships exhaust pipes, he's a catholic converter.

So I rang up British Telecom, I said "I want to report a nuisance caller", he said "Not you again".

So I was having dinner with Garry Kasporov (world chess champion) and there was a check tablecloth. It took him two hours to pass me the salt.

He said "You remind me of a pepper-pot", I said "I'll take that as a condiment".

Now did you know all male tennis players are witches, for example Goran, even he's a witch.

And I've got a friend who's fallen in love with two school bags, he's bisatchel.

So I was in Tesco's and I saw this man and woman wrapped in a barcode. I said "Are you two an item?".

So a lorry-load of tortoises crashed into a train-load of terrapins, I thought "That's a turtle disaster".

Four fonts walk into a bar The barman says "Oi - get out! We don't want your type in here"

Using Windows CE or XP as a real-time OS is possible, it's just a matter of warping time. Time warping isn't possible yet, but the Microsoft RTOSes that use this feature already exist. That's how far ahead of the curve Microsoft is.

WinXP and the newbie Roboticist trap (4, Informative)

snatchitup (466222) | more than 11 years ago | (#6180771)

Many people start robotic projects fearing embedded development. So, they think, why can't I just control everything from my PC.

The problem with this is, it actually adds complexity.

Typically, it means adding a MAX232 with Charge ups, or the more expensive MAX233. This, just to convert the RS232 25Volts down to TTL 5volts. Then you need another component to translate the characters into logic. What a pain! Not to mention a tether.

Better to just learn a little assembly. It's really easy for these applications. Just turning things on and off is setting/clearing a bit in an output register.

Software, is really not that hard, in fact, possibly overrated in terms of the complexity of building one of these beasts. It's the electronics, and contruction. Getting things to actually move.

Matrix Gets Egyptian Ban For Explicit Religion (-1, Offtopic)

Anonymous Coward | more than 11 years ago | (#6180275)

pajor [gnuyen.org] writes "BBC News is reporting that that The Matrix Reloaded has been banned in Egypt [bbc.co.uk] . The country's censorship board cited violence which might 'harm social peace', but also said the 'religious themes' of the film's storyline, about the search for the creator and control of the human race, may cause 'crises'. A statement said: 'Despite the high technology and fabulous effects of the movie, it explicitly handles the issue of existence and creation, which are related to the three divine religions, which we all respect and believe in.'"

Baby found beheaded, gutted
Posted Wed, 11 Jun 2003

A 30-year-old Modimolle (formerly Nylstroom) woman was arrested on Wednesday after her mother found the woman's six-month-old baby beheaded and gutted in her room, police said.

Captain Malesela Ledwaba said police were summoned after the grandmother found her granddaughter's headless body. The girl's intestines had also been removed in an atrocity during the night.

"After some preliminary investigation the head was found buried in a shallow grave on the doorstep of the back room," Ledwaba said. The intestines were found hanging from a coat hanger next to the bed.

Ledwaba described the scene as particularly gruesome.

The baby's mother was then arrested and admitted to hospital under police guard.

The woman's motive for slaughtering the child and ripping out her intestines was not known and she appeared to be catatonic.

Buoyancy (4, Insightful)

Rosco P. Coltrane (209368) | more than 11 years ago | (#6180317)

waterproof version of RHex, which was made neutrally buoyant

How did they do that ? Depending on the density of the water you immerse the thing it, they might approach neutral buoyancy by adjusting the amount of ballast manually, but they'll never achieve true static buoyancy without some kind of active process controlling the amount of water in a ballast tank. Otherwise the object would sink to the bottom or bob up to the surface eventually. Or do they maintain the thing's depth in the water with dynamic buyoancy using the robot's forward movement ? I don't see depth control planes on the robot, could they use its legs to achieve this ?

Re:Buoyancy (5, Informative)

Coelacanth (323321) | more than 11 years ago | (#6180359)

You can make an object neutrally-buoyant (or close enough to it) by carefully adding foam or other light stuff (ping-pong balls!). The tricky bit is making it not only neutral in an overall sense, but to prevent the object from tending towards a particular attitude in the water.

And unless you fill the tank with salt water or, perhaps, lime jello, the density of water is pretty much the same everywhere :-)

Re:Buoyancy (0)

Anonymous Coward | more than 11 years ago | (#6180436)

Erm... huh? Since when ? In water, which is nearly incompressible, the density is the same regardless of the pressure (well it's not, but it's totally negligible compared to the changes in density due to the salinity of the water).

Go back to school.

Re:Buoyancy (1)

aaarrrgggh (9205) | more than 11 years ago | (#6180758)

Water is incompressible; the only potential impact on neutral bouyancy is if the shell of the robot can deform, thereby reducing its total displacement. (Foam or ping-pong balls would have this problem, if used for neutral bouyancy.)

Re:Buoyancy (3, Insightful)

Zog The Undeniable (632031) | more than 11 years ago | (#6180772)

OK for shallow depths, but as the robot gets compressed at greater depths, its volume decreases and it will sink faster and faster (like a submarine that blows too much air from its tanks). There are also problems with temperature change. There's an interesting passage in Lothar-Gunther Bucheim's book "Das Boot" (better known as a TV series and film) where the Chief Engineer explains the variable buoyancy problem caused by temperature, depth and varying salt concentrations to the narrator. The U-boat has to take on or lose a surprisingly large weight of water to compensate for even a 1 degree change in water temperature.

But I digress, I doubt there's much call for a deep-sea robot cockroach.

Re:Buoyancy (1)

FreakyDeaky (680271) | more than 11 years ago | (#6181718)

Could the Robot's body itself be the depth control planes, I mean like by tilting the things body using moving weights or something. I'm by no means an engineer so i was just wondering if this was possible.

Re:Buoyancy (1)

Pvt_Waldo (459439) | more than 11 years ago | (#6181811)

Don't forget it is the density of the vehicle that counts, not it's weight. So instead of changing it's weight, you change it's volume. Easy to do if you have some kind of piston which has one end open to the water. Move the piston out, you increase the volume of the vehicle. Move it in, decrease the volume.

Re:Buoyancy (1)

anactofgod (68756) | more than 11 years ago | (#6182048)

You don't see "depth control planes"?

Really? I see six of them. *g*

Well, I guess they technically aren't "depth control *planes*", but by altering the angle thru which the various flippers oscillate in relation the the body, the roach can be made to level, dive, rise, roll, etc.

Watch the whole clip and prepare to be amazed.

Having participated in a previous life in the building of underwater robots to test system, designs, and procedures related to space station maintenance, I can tell you that making a robot (even a large robot) neutrally buoyant (and "attitudinally/orientationally neutral") may be a real pain in the ass, but it's hardly rocket science. Especially when that robot is being operated in a controlled environment like a neutral bouyancy facility (ie "swimming pool").

Wish I could prove with u URL of some sort but I'm 2000% positive that I've seen galloping robots in a documentary years and years ago made by some university or MIT. I remember that they were made using hydraulics and that they had quadrupeds and even a monoped running/hopping through the hallways (with the researchers running to keep up with cables and such ;-) I also remember that the movements were not preprogrammed but the system "learned" how best to cope with N legs. It developed all of the gaits found in a horse for example. Very good stuff.

You may be 2000% positive, but the assertion that no galloping robots had ever been made (until now, by MIT or anyone else) is backed up by Schmiedeler and Waldron's IJRR paper entitled "The Mechanics of Quadrupedal Galloping and the Future of Legged Vehicles". In it they state "To the best of the authors' knowledge, however, no artificial legged system has ever been operated in a true gallop. Raibert's (1986) quadruped used its legs in pairs, employing trot, pace and bound gaits." The MIT work that you are referring to is that done by Marc Raibert.

Yes, the swimming robot version is cool, but the original rhex robot is pretty incredible too. I work in the lab at UMich where they're working on the land-based one. A friend of mine used a learning algortihm called Amoeba (sort of a hill-climbing approach using simplexes) to speed it up dramatically. It runs fast, much faster then you would expect a stocky little robot with six legs to run. Currently, they're working on a vision system so it can track objects and follow lines, and having it sense its terrain and modify its gait accordingly. Not your daddy's robot!

Already done better (3, Interesting)

Anonymous Coward | more than 11 years ago | (#6180517)

In this year's Technogames (in the UK, broadcast on TV by the BCC), there was a robot that could swim underwater. It swam like a fish, with horizontal tail movements, and knew when to move up or down to stay slightly below the surface of the water. It was autonomous, not remote controlled. Much more impressive than the movie of the swimming cucaracha.

I saw that also. Didn't they have plans to develop submarines and boats with that kind of propulsion instead of screws?

That one would have problems when it got onto land. This bot could be made amphibious by stiffening the "flippers" enough to support its weight on land.

Whatever happened to the wheel? You know that wonderful invention that converts rotational motion into linear motion. Hey, our offroad vehicles use it. Are our robots too good for such antiquated ingenuity? Is the answer simply too easy to give the robotics community the type of intellectual hooplah they thrive on? Or is there some technical reason why trying to make a robot walk is better than letting it roll?

Walking machines will always be able to reach more places then rolling robots.

However, the faster robots will (should) always be the rolling ones.

It is too easy to program wheel-based robots. They seem to be used more frequently for following black lines on the ground, object avoidance, and following walls - things like that.

On the other hand, walking robots often have multiple servos at each leg. Thus, in order to take a few steps, it requires a complex progression of commands that cause each leg to lift, rotate forward, and so on.

loop thru legs 1 - 4
Shoulder servo: up 45 degrees
Elbow servo: up 30 degrees
end loop
loop thru legs 1 - 4
Have servos return to neutral position
end loop

All that just to take one step.

Once you have the basic walking mechanics down, you can invent different paces, gaits, and variations on the theme. You can use a controller chip such as the basic stamp to program all this stuff in (http://www.parallax.com).

Then, once you have defined 'walking' from a programmatic standpoint, you can use an RC adapter to send commands to the basic stamp, which interprets the signals as forward (run the embedded walk program we defined above), backward, etc. Much more interesting than rolling about!

Plus, alot of these robot guys have BattleMech fetishes. They won't quit until there are Ullers running around the lab.

From what I could figure out before it was Slashdotted, the advantage of legs is mobility. RHex , for example, can run over obsticles that are the same height as it.

Wheels are limited to obsticles smaller then the radius at low speeds, and considerably smaller than than that at high speeds. No idea what the actual formula is though - anybody know?

Re:Complicated much? (1)

LeoDV (653216) | more than 11 years ago | (#6180801)

Probably the same reason we evolved with legs and not wheels. :p Legs are much more handy. A robot on wheels wouldn't be able to go up or down stairs (which will be required when they're used domestically), will be less manoeuverable/adaptable the topology of his environment, etc.

But yeah, you have a valid point. Actually teaching a robot the complex algorithms it takes to walk on legs always was a challenge waiting to be tackled, and I'm pretty sure the challenge element was part of the decision process.

But if I had to pick a deciding factor, you have to keep in mind that the entire field of robotics is aimed towards, in the very long term, making androids, that is human-like robots (I think we've all seen that robot from MIT (?) who is capable of expressing facial expressions through the use of flexible plastic eyebrows and lips), and not the ones we already have to build cars, and that includes walking around on two legs.

Re:Complicated much? (2, Interesting)

Dylan Zimmerman (607218) | more than 11 years ago | (#6182335)

Robots with wheels certainly can go up and down stairs. They just have to use a strange arrangement of wheels. Specificaly, triangles of them with one wheel at each vertex. When one wheel encounters a pothole (or in this case the gab between two steps' edges), the entire assembly rotates. It works rather well. I've seen a robot designed like that climb about 20 stairs in the same time that it would take to go about 15 feet. The rotation slowed it down a bit, but really, it was pretty efficent.

And the robot from MIT that can do facial expressions is called Kismet. Quite a cool idea, but it can't do much without a mobile base. Right now, it just sits in a room and waits for people to interact with it.

In my opinion, Cog is much more impressive because it learns. They showed it how a toy car works and it learned how to move the car very quickly. Cog actually learned that the car would only move if it is pushed on the front or back, not the sides. Now that's an acomplisment.

Re:Complicated much? (4, Interesting)

nvalid (158468) | more than 11 years ago | (#6182188)

There are at least two advantages to legged robots that I'm aware of (though the technology is not necessarily there to take advantage of them). The first is the potential to climb much larger obstacles for a robot of a given size. Robots using rocker-bogie wheel systems such as the Mars Pathfinder vehicle have amazing climbing abilities, but this is nothing compared to what a human can accomplish.

The second is a potential energy savings. Imagine a wheeled vehicle traveling over rough terrain. It's constantly climbing over obstacles which takes energy that is just lost when it falls down the other side. Meanwhile, a legged robot can keep its body above the height of most obstacles and just step over the top of them -- more of its energy goes towards its forward motion instead of the up-and-down motion of the wheeled vehicle.

Oh, another thing is the ability to tolerate loss of an actuator. If one of the wheels were to stop working on a wheeled vehicle, the rest of the wheels would have to drag that one along. Meanwhile, there's been some neat work showing the robustness of legged robots to such problems by groups such as the Biorobotics Lab [cwru.edu] at Case Western.

In the end though, it depends on your application as to which is best. I just can't see that one approach could be better than the other in all cases. Just as one example, I think legged robots have really cool potential for planetary exploration for the reasons given above, but certainly anything spending most of its time on flat ground (agricultural equipment, anything on-road, etc) would perform better with wheels.

Dr. Smeegee (41653) | more than 11 years ago | (#6183231)

On a large machine that must pick it's way carefully through a delicate area, legs may be a decided advantage.

Scope ye the Plustech [plustech.fi] Harvester. It uses six hydraulicly actuated legs and a big-assed arm with a gripper/saw on the end to harvest trees from delicate areas.

Some guys I went to high school with use horses to harvest hardwoods from Indiana forests due to the trees inaccessability to wheeled vehicles.

Legs are useful!

Just great. Now I have to keep a portable EMP generator next to my cans of RAID under the kitchen sink. Do you know how much power those f***n things use?

Let's hope they don't teach the little bastards to breed. What will they do, lay their eggs in my box of spare PC parts? Although I assume there'll be a nice satisfying mechanical *crunch* when you step on them.

Gives new meaning to cockroaches carrying diseases. Maybe they'll find one that transmits W95/Klez@mm. Norton Antivirus will now cost three times as much to ship, because it comes with a large hammer. Don't download files, don't open mail attachments, and put a ring of flea powder around your PC. "Dr. Solomon..." *WHAM WHAM WHAM* *crunch* "...has detected and isolated a virus."

On the other hand, it'd make for a nice way to smuggle an X10 cam into a cute girl's bedroom--assuming they ever make the transmitter units weigh less than 5 pounds. Blattidae Elegans Electronicus indeed.
