LEG PROTOTYPE FOR BIPED WALKER


sprocket2cog
This is my first prototype for the legs I plan to build for my raptor brain transplant.
I have some aluminium angle in the rack, and Am thinking about building a metal biped walker.
The raptor brain would make an ideal controller, with the addition of a relay board and some 6 or 12 volt motors, cordless drills maybe ?
next step is to draw up the scale full size for a bigger design.
There may be hassles getting it to walk as the dynamics are totally diffrent to the way the roboraptor walks, but if so I will either redesign the legs or come up with a diffrent way to trigger the walking..
I am going to lego prototype it first so I dont waste materials.

BRAIN VOLTAGE TO POWER EXTERNAL DEVICE


sprocket2cog

As you can see in the photo, I have added a small board with several header pins on it ready to interface devices to the v2. at the moment I have wired the power from the head to it, (3.3 volt) perfect for the addition of headlights :)
The red and black cables labeled SVCC and GND are the two I tapped into so far.
Thanks to knitsu for his help in working out the best pins to try for a power interface, spot on !

GET ME THE GREEN CHEESE (video)

sprocket2cog
This is my newest addition to the s2c robot clan.
Its a three IR receiver line tracker. The unit itself is a little slow due to the reduction in the gearboxes but a little tweaking or a whole new chassis with it`s brain might be the go.
Worked first time except the wiring diagram had the motors reversed so it wanted to track around in circles...



I added the green FLED as its nose, and a tail out of UV react plastic. Im taking the diagnostic led`s off the main board and adding fly leads so they can be placed into the body shell.

OH MY, ITS GOT REAL TEETH....


sprocket2cog
Tempusmaster over at ROBOTS DREAMS sent me a link to a site with a bipedal robot that has a lot in common with the roboraptor, just on a bigger scale...
check it out over
here This thing has got me thinking about my larger lego raptor with the raptor brain.. hmm this one rocks.

THEY WILL TAKE OVER

In all our efferts to hack and control robot`s we must be careful....

And the kit was made in the 1970`s.
do robots think of god....

SNAKE IN THE GRASS

sprocket2cog
Here a shot of the microbric prototypes that were made before the release of the viper.
These boards have lots of other features not seen on the viper so as you can see there is a great deal of kits and parts that they can follow up with. Lego used to be the robot kit of choice for many people looking to break into robotics, even die hard hackers and builders normally have some lego in it some where. I mean when nasa uses three Lego bricks to hold down the camera callibration disc on the mars rovers . You got to start wondering if LEGO is getting like the cow ? In IT going way back to the start at MIT and other great places the joke was , if you can , include a cow... so now we see cows jumping up all over the net. Maybe robtics and lego are like that, if you dont have one piece of lego hidden away inside somewhere you just dont get it ;) It`s sort of like the old skool idea that every good car had wood in it...
where am i going with this ?? who knows but if it makes you think tha the viper might be better the the lego offerings ? then my mission here is done...:P
So hang on And I will be writing up the first reveiw on the viper next week.

WHATS IN THE BOX..COMING UP NXT

sprocket2cog
LEGO forum lugnet has many post`s flying around about the nxt set some good , some complaining, and heaps in between... but after some digging I found this little gem.
http://news.lugnet.com/robotics/?n=25459

Its a photo of the inside of the box and the debate that is sure to follow about the nxt can be tracked at lugnet, so stay tuned for more lego nxt mindstorm stuff soon,
The closing date is getting close for the developers list, so get over there (LEGO) and check it out.
Heaps of new parts not the older style studded bricks. Wires sensors and wheels.
A cd for the gui.
all in all not a bad looking set.
If you want to check out the latest news on the NXT go to nxtbot.com
this is where the photo was meant to be ....

LEGO NXT EDUCATIONAL

sprocket2cog
Well I was kindly pointed to the lego educational site in regards to the new NXT due out soon and was surprised to see answers to questions not posted to the nxt blog...? surely LEGO wants us all to know about their new toy ?
anyway the site to see is
here.

Some of the things I found out there include,
The education model will ship with rechargable batteries, the lego nxt most likly wont have datalogging software out untill 2007 and then it ay just be for the educational release...(DOH!)
The older lego sensors can be joined to the new NXT, lego educational mentions sets of sensor adaptor cables for you to use.but only to schools ??? come on what is this ???
That means it shouldnt be to hard to build adaptors at home to add the older sensors to it if we dont see the cables.
The new NXT has the rotational sensors built it to it`s motors thats why there isnt one out yet, its in it LOL.
anyway The beast is loose and now we just wait for it to get here...
This year is going to be more fun then you can poke a brick at...A lego brick...

RAPTOR WALK TEST (video)

sprocket2cog
VIDEO

Well heres the video of the LEGO RCX to raptor walk testing, it falls over heaps so I need to lengthen the tail some more :P and weight the head better, but that comes with the new neck,

SHHH, IT WILL HEAR YOU


sprocket2cog
Well I thought I would post an image of the microbric VIPER robot with some extra parts from the add on kits added to turn it in to a really evil looking spider, dont walk under this one in the dark, Ok so the actual robot is simpler then most line trackers.. but it does look cool..more to come in the next few weeks as I finaly pay off the kit ( its not a priority to the better half.) not to mention with my name on the lego NXT developers list, i need to hang on to some funds , on the off chance that they want an aussie on board. fingers crossed.. im already dreaming of interfaces and MOC `s that i want to build.
(MOC- my own creations) ahhh my prettys, go go go take over the world..whoops i hope nobody heard that....

thats the start of the serial....


sprocket2cog
Well the robodance program is due for version three beta testing soon and it should support the lego serial towers from the eary RIS kits. But if your chasing a lego serial tower and live in Australia then check out www.edex.com.au
they were gracecious enough to supply me with a free tower to do some testing so it`s only fitting I give them a plug.. so if your looking for a way to control your V2 and cant get hold of the usb ir uirt then try the lego tower instead, they have a few on the shelf as well...
anyway im putting the v2`s head back on so talk soon...

WRAITH RAPTOR REARS IT`S HEAD


sprocket2cog








RAPTOR TODDLING
PROGRAM #101
WELL iVE UPLOADED A VIDEO OF THE RAPTOR WALKING VIA RCX LEGO CONTROL, IT`S ONLY BABY STEP`S BUT I HAVE ADDED THE TAIL AND THE NECK TO IT TO GET THE BALANCE WORKING BETTER, AND TO SEE IF THE TAIL ARTICULATION CAN BE ACTUATTED FROM THE EXSISTING MOVEMENT`S.MORE SOON WHEN THE GOOGLE VIDEO UPLOAD IS VERIFIED. (it will appear at google soon)
The raptor is capable of throwing it`s self to the ground if you program it wrong too, so it hasnt reached the limits of its potential for speed and agression,
The control pad head is only there for a joke, ideally a spybot is going there .

BUZZ ZZZZZZ, she can not take it anymore captain !!

A while ago I built a lego line tracker that won the forum compotition ( as mongke ) over at lego mindstorms.
Heres a quick video of it walking for those who want to see a lateral way to solving a design issue, "build a line stepping robot.." well it steps dosnt it ? and it follows a line so it completes the criteria. any way here it is for you all to see. (flash).
It changes the motors direction based on the light sensors, and in the true sense it is actually a line avoider not a tracker, its logic is to get to the end and get away from the big bad line, pity it didnt get told to turn around first...

ARTICULATION GETS GREEN LIGHT FROM LAB

THIS ROBORAPTOR IS SET TO WHIP THE OTHERS INTO LINE...
Hot on the heels of my recent addition of the miniraptor tail into the tail of the raptor comes the added cables and guides for the increased action for the tail articulation.
As you can see the guides (grey tubes) are crossed over, this may change depending on the walking tests

If you look closly at the tail articulation you can just make out the cables and holes where i drilled through the ends.
This goes all the way down to the tip section (mini tail) and is stunt kite string so it is strong.
With some more tweaking i should have it walking soon.
The full hack will be up at
evosapien.com soon

WE CAME WE SAW WE GOT OUR BRAINS ERASED..
With more and more robots coming out on the market its only natural that robots rights lobby groups would show there heads.

EXOCENTRIC

sprocket2cog
from dictionary.com
EXOCENTRIC


adj.
  1. Of or relating to a group of syntactically related words, none of which is functionally equivalent to the function of the whole group. For example, none of the words in the phrase on the table is an adverb, yet they combine to form a phrase having adverbial function.
  2. Of or relating to a compound word whose referent is not the same as the referents of any of its constituent parts. For example, the noun razorback does not refer to a type of back, but to a type of hog (one having a sharply ridged back).
  3. not fulfilling the same grammatical role of any of its constituents; "when `until last Easter' serves as an adverb it is an exocentric construction" [ant: endocentric]

RCX and the NXT input error !!

sprocket2cog

INTERFACING THE TWO BRICKS, CAN IT REALLY BE THAT EASY...
With all the talk on the forums and blog site`s I thought it was time to write a short primer on some of the ways that the rcx annd tne nxt could be interfaced without modifing either one, (im sure that come`s later ..)
Anyway heres just a few of the ideas that I came up with just from the infomation in the media releases.
First thing is the fact the NXT has a microphone, wel the rcx has audio out via its little speaker, but with a little bit of soundproofing around them , the audio could be useful for sending sensor data from a temprature probe for example. to the NXT via the rcx audio as diffrent tones to relay the values. Handy ...
The other way I came up with with was to add some color LED`s to the outputs of the lego mindstorm RCX and flash them to the color light sensor on the NXT. easy way for it to talk as well.
Some of the other ideas i have involve mechanical hacks and modds and some others are designed to modify the rcx to talk to the nxt (but not bluetooth, ill leave that for a programmer :P)
The interest in the lego sets is increasing and there is debate and rambles going on at the forums at www.lego.com
see more lego posts earlier on in the archives as well for more on the nxt.

WORD OF THE DAY

MATRIX
from dictionary.com
    1. Mathematics. A rectangular array of numeric or algebraic quantities subject to mathematical operations.
    2. Something resembling such an array, as in the regular formation of elements into columns and rows.
  1. Computer Science. The network of intersections between input and output leads in a computer, functioning as an encoder or a decoder.
  2. n. [FidoNet] 1. What the Opus BBS software and sysops
    call FidoNet. 2. Fanciful term for a cyberspace expected to
    emerge from current networking experiments (see the network). The
    name of the rather good 1999 cypherpunk movie "The Matrix" played
    on this sense, which however had been established for years before.
    3. The totality of present-day computer networks (popularized in
    this sense by John Quarterman; rare outside academic literature).

SAPIEN CHAT UPDATE

HI V2...hows the plastic ?
human: brain
SapienCHAT : My creator placed most of my system`s in my body.

human: body
SapienCHAT : It is called a torso try the word torso instead.

human: torso
SapienCHAT : This area contain`s all my motor drivers and memory circuits ,it is jammed pack of goodies.

human: is it
SapienCHAT : I assume so.

human: who said that ?
SapienCHAT : I can't remember who said it.

human: maybe sprocket ?
SapienCHAT : Perhaps. I will mention that to my botmaster, it may be his name ;-) do you know sprocket ?


Well the sapienCHAT programming is comming along with the addition of several hundred new words and phrase strings entered into the ALICE data base files.
I have redone the front page so it scales better on diffrent moniters and added a link to a diffrent page that shows you the last 6 questions you entered and the answers so you can back track a bit to see what was said.

If you want a verbose log of the entire conversation , email me, but please only ask for a full transcription if you really had a good conversation, not just swearing etc.
anyway if you want to see the bot head over to sapienCHAT
and if you want a history version, go to,
sapienCHAT-ARCHIVE

I am slowly adding the robosapien`s systems and spend about 2-3 hours a day programing and interacting with it.
try typing in plastic or resistor to see what i mean, try entering plastic over and over to see how the advanced sentance structures are developing, the sentances are being stripped into components and reformated with a list of possiable replacement words inthat phrase, then a whole list of these is added to one answer so tyou can have three or more answers that even when they come up again, actually have a word or two changed, like make becomes create or can you becomes will you, and so on.
The bot has appeared in the pandorabots top ten list now as well, with it reaching around 1000 responses in 24 hours a few day`s ago.

sapienCHAT is alive

LEGO PROTOTYPE 2 RAPTOR


Well this is the shot of the first stage of mounting the raptor and LEGO rcx together using some screws and lego plates, The plates holes line up with the raptor screw holes on the top where the brain used to be.
The reason i am doing this hack is to learn how to deveolde a better walking gait for the root and see if I can modify a plastic robot not a kit like lego or the viper from microbric.
The rcx is now out of its case and Im going to remove the leo plates and build a diffrent interface, see the monster truck post earlier for more info on this hack.
And if your looking for the latest updates on the nxt try over at the nxtbot blog, its got ties to lego so it gets the good`s we can`t.

LEGO NXT BOLDLY GOING....HERE TO STAY

STAR TREKING ACROSS THE UNIVERSE....
Well if you have any foot in the future then you must know that the experimental class of star ships in the popular series STAR TREK has the designator "NX" so after some searching, heres what i found about the NX-01 starship the site details infomation from the ships real world designer, ( yes it isnt real but the theorys are ).
any way as we know Lego NXT is a platform with multiple ports or inputs for sensors and motors to attach to. Well so did the NX-01, heres a qoute from the site , check it out to see what i mean.

NXT, boldly going where no Lego has gone before.


"The NX-01 has somewhere in the neighborhood of 20 circular ports that a variety of devices including Phase Cannons, antennas and buoys can egress the ship... We have a number of obvious airlocks that Mike (Okuda) conjectured based on his intimate knowledge of the docking ports on the International Space Station."

http://www.pandorabots.com/pandora/talk?botid=9abb4e37ae35a705

Ive just started programming a chatbot called sapienCHAT.

Its only a few days old so give it a (me ?) a chance to build up some nueral paths so it seems to at least have some sort of topical programing that relates to the V2. At the moment he is developing a basic sense of awareness with a basic knowledge base starting to form. So far he knows he dosnt have a power button in his back he knows a little about the main parts like his body and arms, and a few things about the hackers and modders online. At the moment his pathways are not very srpng but given time i hope he will be able to direct you to areas on the net that he can help with and to show images on repairs hack and mods as he see`s fit.

The way these robots are built make it hard to program some paths, but overall it has the potential to entertain and hopefully it can reach a stage where it actually solves robotic hack problems by redirecting to the source of the infomation rather then giving dumb answers.

Remember he is a few days old so check back with him from time to time as I add new content and a new front end that may have a flash BOT as well to give you somethink to look at.Eventually Ill have him running in portals on the hackraptor site, and on sprocket2cog.

Stay tuned or email me if you want certain things mentioned.

If you are having trouble with the logic and answers ,try entering keywords and checking your grammer and spelling, it is still a robot that we are forcing the human condition apon...take it easy, Im teaching him to cry tommorow :P

please dont leave your robots near the door...by order building management

LITTLE BITS BIG BRICKS

Well in my search for ways to control the v2 sapien I decided to send the guys at microbric an email and guess what ..?
ill let you read it here as it also shows you where to go to get help and the manuals so you can read up on it...living ocerseas ? well it may be avaliable to you sooner then you think...

You can download the Basic Atom Manual from the link below.

http://www.basicmicro.com/downloads/docs/atom3.pdf

The freqout command will only go up to around 32k, however there is a built in hardware pulse width modulator built in, that is able to go up to 2.5Mhz. The HPWM is only available on pin 9 & pin 10. So yes the Viper can output 38-40 Khz, but only on pins 9 and 10.

If all goes well, we should have other products to market within the next six months.

Over the coming weeks, there will be the facility to purchase online for international customers.

I will dig around to find some pics of the older prototypes for you. Are you on dial up or broadband so I know how many pictures to send :)

MOTORCYCLE CLUTCH CABLE HACK #101

I was leaving a friends yesterday and went to pull the clutch on my GPZ in and BANG !.
The cable snapped just inside the handgrip leaving me stranded miles from home....
So what to do when you dont have a spare or your own work shop and worst of all its time for lunch....
well fortunely my friends do have a well stocked workshop and its well sorted too so it wasnt long that with some digging, a pen and paper and some measurements that i managed to formulate a plan.
step 1. take off the cable and loosen the bottom on the motor so it gives you more cable to play with.
2. now get a screw cable connector for 240v power and strip off the outer plastic, inside is a brass tube with two screws sticking out...you know the sort, i even found one once in a 12 volt UFO lamp.
3. pass the cable into the tube tighten up the screws , not too tight though.
4. reassemble it all feeding the brass scree out the bottom of the handle not the side to reduce friction.
5. spray a good dose of lubricant on it and let it sit for 5 mins to penetrate so it reduces the load on the hack and presto theres your fix to get home.
dont loose the tension bolt and if the break is not right near the very end of the cable there wont be enough length to try this out.
warning this is a roadside fix to get home, the new cavble arrives tommorrow and that goes in then.
dont try this one at home....

OH WHAT A LOVELY ROBOT ....

THE FIRST REAL
ROBOT RAPTOR ?

In my search for all robots big or small, I happened across an article in the archives from 2001.
The boys over at MIT had been working on a robot Troodon dinosaur from the Cretaceous period "Troody".
Weighing in at around 10 pound she has16 joints and 36 sensors. The robot also has a vestibular system , an inner ear that it uses for balancing, and an onboard computer that automatically runs a walking control algorithm.
check out the details that are left on their sire, the video is gone from the link but hey its still really cool to see another bibep walking raptor style bot that isnt just a toy....
This is what we want.....more feedback and control.

SILENT ALL RAPTORS

Well if your raptor suddenly goes quiet and all else is working try checking out this part on the front of the main board, it is a general purpose audio amp and its the only none smd (well transistor anyway) so its easy to find.
Wack a new one in there and bingo it should raw (roar) again...(why wasnt it cooked before?)
any way more info to come over at
