So I take it you got the thumb-joysticks to work? Do you have a pinout?

It's quite a neat hack, though I've never been fond of those controllers...

[Rohan_DHS]

Thats too cool! Any diagrams (aka pinouts, like phrontist said)?

Also, did you get the vibration thing working too lol?

[Ian Curtis]

How do you get good control with the analog sticks? I believe the resistors in the sticks themselves are 10k Ohm and joysticks have 100k ohm resistors.

[Bcahn836]

Where you able to add any function to the buttons, for example using R1 R2 L1 L2 for say arm controls?

[Joe J.]

I don't know all the details they just let me drive it. I've passed along your questions to the guys who built it.

Also, did you get the vibration thing working too lol?

We're working on it.

Yes they put the arm controls on the front trigger link buttons
arm up is on the top right
arm down is on bottom right
arm extend is on the top left
arm retract is on the bottom left
Tetra wacker is the circle button
Dumptruck is the triangle button
Tank drive on the joysticks

How difficult is it to drive with the ps2 controller, and i have to ask the obvious question is it like playing a video game? What are the characteristics of the controller?

[Joe J.]

For one person to drive its alot easier to drive with the PS2 controller, The robots alot more responsive as well. The only problem is after you go backwards and release the joysticks it tends to keep rolling backwards but they working on it.

Very cool!

ok, i'm one of team 862 electronics monkeys who worked on this, i'm working out some more bugs and will have plans and/or schematics soon

but it works like this
a PIC16f688 reads the ps2 controller data (yes, no controller mods, that controller is an unmodified commercial controller i bought used like 2 weeks ago)
it decodes the signal and sends the info to some Digipots (maxim-dallas copyrighted term) that have 100k impeadence (theyre 100kpots like in joysticks) they contol everything

you have to change youyr software though if u wanna use ours, it uses 1 joy stick port

[GhostInTheShell]

also rohan_dhs, we are working on the rumble feature currently, it needs pwm1 to be clear though, it uses the feedback lights for pwm1 to tell the pic that "holy crap we did sompthing wrong" like if we hit sompthing or we have a malfunction

How did you program it?

[d.courtney]

I haven't been on Chief Delphi in a while and was suprised to see this topic as I did it in September. Its nice to see the same idea I had others had as well. But yeah I used http://www.levelsix.com/product_info.php?products_id=35 as my ps2 (well actualy I used my old ps1 controler) and it seemed to work great, there was a minimal amount of programming (just had to edit some of the input values). I really enjoyed the fact that I didn't have to program a dead zone as the anolog sticks automaticly returned to dead center (or close enough that it didn't matter in my case) ... the thing I don't understand is how people think this is against the rules, as the controller has the same setup as a joystick pretty much. The difference maily being that it has a rumble ability (which for some reason I am having trouble to program).

Well anyway against the rules or not thats what I did... I hope for my sake it isn't agaisnt the rules.

Wait so how did you go from the parallel to the game port. Or did you modify it? Basically how did you connect your controller to the operator interface using that adapter?

[Rickertsen2]

so.... how about that source you promised.....
