nxt controler

Use my nxt as analog controlor the motor angel sensors

So you can control an robo ARM whit a robo ARM
Can by nise

the default nxt firmware won't work well with robotic arm controlling, simply because it has no trigonometric functions at all. i have failed miserably at it already, during preparation for the brazilian robotics olympics.

meanwhile, here is the formula i tried to use, "converted" to lua

Code:


    function ikcontrol(x,y.flip)
    local d= (x^2+y^2)^0.5
    if d>2 then d=2 end
    local a= math.atan2(y,x)
    if flip then k=-1 else k=1 end
    local a1=math.deg(math.floor(a+(math.acos(d/2))))
    local a2=math.floor(-2*math.acos(d/2))
    return a1,a2
    end


you should try using the NXC firmware instead.

Thanks for thinking whit my but I mean robot in rc controled by nxt robot ARM

So if I turn an nxt engine 180 degre the robot in rc does tlhe same or is that the lua you made .I don't no how to use lua
Is the nxc filmware free and is it like the script in rc I like that

I'm that guy on the orz server whit doderijk4
I had that red sing and I made an model like your floating thing in 5 minutes

(epicbump) you'll also need to create a mechanism to map usb input and convert it to keyboard-like input(i don't think RC supports lua's i/o library).
