Hexapod Futaba servos! Left right have switched! [FIXED!]

Ever since i build my Phoenix like hexapod, The turning or walking to left or right is the other way around. Can someone please tell me what i did wrong? It walks fine but it anoying to have to think everytime before i steer.

Also i’d like to know how i can make my hexapod do the attack mode under the “cross” button. I’ve searched everywhere and tried putting the code from powerpod in the Xan file but it gave me only errors.

I think this code isn’t compatible? :cry:

Are you using the Phoenix code? Maybe you could post the section of code where TravelLengthX & Z represent the input values from the joystick. Is your’s the same?

	TravelLengthX = -(Dualshock(5) - 128)

Has a negative sign, do you have it? Or you might try removing it.

Alan KM6VV

[code]IF (DualShock(2).bit1 = 0) THEN ;R2 Button test
TravelLengthX = -(Dualshock(5) - 128)
TravelLengthZ = (Dualshock(6) - 128)
ELSE
TravelLengthX = -(Dualshock(5) - 128)/2
TravelLengthZ = (Dualshock(6) - 128)/2
ENDIF

  TravelRotationY = -(Dualshock(3) - 128)/4
ENDIF

;Calculate walking time delay
InputTimeDelay = 128 - (ABS((Dualshock(5) - 128)) MIN ABS((Dualshock(6) - 128))) MIN ABS((Dualshock(3) - 128))

ENDIF[/code]

Wich one??

Here’s the entire code

There are two TravelLengthX statements, one for slow gait, one for fast gait. Try removing both the - signs, and see if you get a change.

Another way to look at the problem, how have you set up your legs? I’ll bet the Phoenix has both a left-hand and a right-hand leg. If they were reversed, you’d get reverse leg turns.

Alan KM6VV

i tried that but itt’l screw the legs up even more. They stand up with the tibia under the body.

If you’re using the same code, and if that didn’t simply reverse the action of the joystick, I’d seriously compare the connections and orientation of your legs and servos.

The differences can be quite subtle. I helped a friend get code running for his DIY hexapod, and it took several go-arounds before we got the code fixes worked out (he couldn’t change his servos or legs).

Alan KM6VV

I tried several pin setups. Non of them worked like this one. also i checked the legs several times. These are also right. I got it working at one time but can’t remember how. I changed the body afterwards.

At this point, it would be good if you could show a picture of your setup which shows the legs and shows which wires from which servos are connected to which pins on the SSC-32.

I agree with Alan that if it simply is going left when it should be going right, changing the sign should work, but my guess is something else wrong, like IO pins for left leg is on right leg…

Kurt

I used the standard pins. As shown in the first table. As for the legs, i cant seem to post any pics or links. I get an error on send. But i can asure you that ain’t the problem.

Mano, Kurt already asked to post a picture showing the setup you’re using. It will be much easier to help you when we can see how you setup your hardware. Both Alan and Kurt are thinking that you’ve swapped the left and right legs. I’m on the same line here :wink:

The Powerpod code isn’t compatible indeed :wink: But the piece of code you’ve posted isn’t to hard to implement in the phoenix code. The build errors are caused by the pin numbers that are not declared. Well, they are declared but with a different name. :wink:

You need to replace the constands containing the pin numbers with the ones used in the phoenix code.

MRHH stands for something like Middle Right leg Hip Horizontal. If it’s defined to pin 12 MRHH will contain 1 and MRHH2 will contain2. The phoenix code uses just one constant for this.

MRHH needs to be changed in RMCoxaPin

SSC32,i38400,"#",MRHH,MRHH2,"P1800#",MRHV,MRHV2,"P1700#",MRK,MRK2,"P1700#", | MLHH,MLHH2,"P1200#",MLHV,MLHV2,"P1300#",MLK,MLK2,"P1300T288",13]

The new code shall look like this:

serout ssc_out, ssc-baud, "#",RMCoxaPin,"P1800#",RMFemurPin,"P1700#",RMTibiaPin,"P1700#", …,"P1300T288",13]

I think you can figure out the rest…

You need to program a bit to get the function to work with one of the buttons. You probably need to dig deeper in to the code to see how the other functions work.

Good Luck Xan

Thanx! That helps a lot. i will figure it out today…

I still can’t post any pictures. I get an error…

This is the pin setup i used…

This site /images/assembly/phoenix/phoesch1.gif

I do not really doubt your pin setup. I’m more looking for a picture that shows your phoenix. You shouldn’t be the first who mounted the legs on the wrong side of the bot. :wink:

You can try hosting the image somewhere else and type out the link without www and dots. This should make it possible to find the image on the web…

Hi Mano1979,

I updated your message with the link. My guess is that you should now or soon be able to post links. I don’t remember the how many days and how many messages you have to be registered before you can post the links…

P.S. - The image is real small and I am not sure I can see anything in it…

Here is the information regarding posting links and images:

Ah thank you! I see. Ig hasn’t been 24 hours since registration.

So did the picture show anything wrong as far as you can see?

Picture is WAY too small to see anything. Try 1024 x 768 or some such.

Alan KM6VV

I will post some closeup pics tomorrow. Have to work tonight.

I think i get it right but when i programm the atom pro 28 it does everything untill i hit the “cross” button. Then everything freezes and after a minute or so it’ll start beeping.

Here’s my code. What is the problem?
