Hexapod Robot - JARPod Extreme Travel

[Geckorule40000]

Now dress it up as a spider and put it in the girls locker room

[riesigesriesla]

how did you make this spider? how did you programm it? Can you make a video how you made it?

[DerTereyses]

Only one question: can it shoot too?

[theMagicSquares]

To say that this is "Quite cool" is an insulting understatement! Even if it can't scuttle along, this looks like one of the most advanced hexapods on YouTube! I usually only watch half of a demo video, but you had me fixed! Great job!

[MrJonagikster]

This is quite cool! May I ask, how did you describe to the device what you wanted it to do? Did you describe the position of the center of gravity and body pitch and then calculate limb position to achieve desired position assuming a flat surface, for example?

[MrTBSC]

i realy wonder how that could be practical in the world

however just for the looks and performenceshow it IS realy cool

well done ...

[Themicles]

IK Math going awry? Nah that's just the ghost in the machine showing off it's moves. :)

[zippy172]

@Themicles lol

[kristijan594]

damn i love it if i was u i was going to build many things and play a strategy game with fighting like red alert or  command and conquer 3 :D

[proud63]

inside body of this machine a lot of space to place a lil'l electronic brain and couple of cams. this thing should be autonomous ;)

[maledikt]

The only question is: Will it blend?

[zippy172]

@maledikt Almost certainly ;)

[Tesujinn]

make a giant (I mean building sized) version of this, stick armour and guns on it and rule the world!

[peruuky]

5 word.

Fucking Awsome!

&

Good Job.

[zippy172]

@peruuky lol thanks! :)

[zippy172]

@peruuky lol, thanks :)

[2310Ole]

cool

[zippy172]

@2310Ole Indeed!

[Videobaschtl33]

I wonder when these will be used in warfare...

[zippy172]

@Videobaschtl33 12th of never... even the commercial systems are just way too slow...

[zippy172]

@Videobaschtl33 12th of never...far far far too slow

[Videobaschtl33]

@zippy172 yet

[CiX109]

i watched a sixlegged thing dancing for like 4 minutes. and i loved it

[zippy172]

@CiX109 Good for you! :)

[minnesotakabaap]

hey ... awesome robot! :) one question comes to my mind though .... how are you generating PWMs for all the servos? Do you have a dedicated PWM generator module? like a microcontroller with software PWMs on various GPIOs?

[zippy172]

@minnesotakabaap All the servos are driven from a FAST PIC microcontroller, PWM outputs each of the gpio lines, behind the scenes is a lot of inverse kinematics to generate the position information...

[zippy172]

@minnesotakabaap All PWM is driven from the PIC microcontroller. All the math for making the legs "walk" is actually inverse kinematics.

[UmatsuObossa]

I wanna see it RUN! Scuttle across the floor like a frightened roach

[zippy172]

@UmatsuObossa lol sadly the servo motors used to get the thing up and walking, are no where near fast enough to make it run ;)

[TheArtyDragon]

*gasp* A dancing bug!

[zippy172]

@TheArtyDragon Indeed!

[ahamedBacar]

hey do I can have the code source of your project ?

[zippy172]

@ahamedBacar Sadly no.

[miniterme]

EPIC buyin!

[miniterme]

niceee

[zippy172]

@miniterme Yeah, I must dig it out one day, spark it up to make sure everything is still in order...then SELL it on ebay :)

[GOLDSPACEVIDEO]

cool dan[e

[Dinoldje]

awesome! wicked smooth movement. Where did you learn to build and program these small robots

[zippy172]

@Dinoldje All the CNC stuff was self taught, I've been a Solidworks user since '96 so was a piece of cake to design the body. Electronics was done by a guy called Matt Denton (Google him) :)

[serpicogattonero324]

whohoah



[zippy172]

The hexapod is controlled via a wireless PS2 gamepad controller. You can see the receiver (red and green flickering LEDs) on the top. The main microcontroller for locomotion decodes the PS2 signals into hex movement commands :)

[Jabarichonicles]

how do u controll the robotics itself and the interface

[RFT15ify]

Cool!

[zippy172]

@RFT15ify Cheers :)

[RFT15ify]

@zippy172 Yeah, cheers. It's expensive right?

[zippy172]

@RFT15ify Kinda...it has over £450 worth of servos, plus the aluminium and electronics/battery...Easily cost me over £600 to build ;)

[LiangHuBBB]

Nice.xd

[zippy172]

@LiangHuBBB Ta :)

[KakashiHatake103]

now imagine one 60 ft tall and in a movie crushing cars. or better yet real life transformers. sweet robot dude, how does it move each leg seperately? does the control have 6 different joysticks?

[zippy172]

@KakashiHatake103 3 servos per leg, all controlled with inverse kinematics driven from a 'fast' PIC microcontroller. The actual input for movement is taken from a wireless PlayStation 2 controller :)

[tatkirulez]

Pretty cool, now only if it shot lazers.

[zippy172]

@tatkirulez I did think about putting a pair of galvos on it to bounce a laser off...mobile 6 legged laser show :)

[BakuganMaxusDrago]

it dances to beat at 0:27 - 0:32

[m6alle3]

cool its eazy and funny

[DeathIIV]

music :D!!!!!!

[F00dTube]

Very nice, well done!

[mov0001000]

Obligatory, frequently asked question: what's the name of the song?

[zippy172]

Fraid to say, I have no clue. I just tried to check by editing the video to see if it listed the track I selected, but alas, YouTube doesn't show the existing track, just gives you the ability to change it for another. Sorry.

[adultricola]

AWESOME

[zippy172]

Thanks :)

[MrLuckviewer]

tell me what things you needed to make a hexapod robot..

[superaznfooo]

abot 1,000 bucks and a few hours of free time

[zippy172]

@superaznfooo It wasn't far off USD1000 to make, and took me about 3 weeks on and off...longest part was machining all the aluminium leg bits and servo brackets.....then all the anodising I did (some bits twice because of poor cleaning) at home too.

[zippy172]

Annotations added to the vid, be sure to hover your mouse over :)

[robotmanx2009]

what is the common way of controlling servos in sync? do you have to program each one running off a pin on a micro controller or do you use a servo controller?

[zippy172]

That's the Playstation 2 wireless controller receiver I'm using to command the Hex :)

[BRACK3N]

Looking seriousely awesome now!

whats the circuit youve added with the LED in front?

[zippy172]

Hitec HS-645MG's all round :)

[lemuriandezapada]

lol man what servos u usin`?

[zippy172]

@lemuriandezapada There are annotations through the vid that explain what servos I used ;)

[zippy172]

@lemuriandezapada All you need to know about this robot are in the video annotations ;)
