Have the formula in audacity to make normal voices sound roboty or as if a robot was speaking?

Like Tachikoma from GITS?

You probably need a vocoder type of plug-in. With Audacity "as-is" you can simulate some robot-like or distortion effects with wah-wah, phaser, Noise Removal at extreme settings, or an extreme hard limit then amplify it back up. As for plug-ins try:
http://www.audacity-forum.de/download/e ... vocoder.ny

This is already included in Audacity 1.3.5. Or try the vocoder plug-ins at this site:
http://www.kvraudio.com/

or the simple vocoder plug-ins "mda.talkbox.dll" and "mda.vocoder.dll"
from this suite of 30 VST Plug-ins for Windows:

To install any new plug-ins in Audacity, unzip them and place them in the Plug-Ins folder inside the Audacity installation folder. On Windows computers, this is usually under "Program Files." The plug-ins are available after restarting Audacity, however should Audacity fail to start after installing new plug-ins, remove them one by one until Audacity does start.

For VST plug-ins you have to add the unzipped vst-bridge.dll from this
download:

to your Audacity Plug-Ins folder, as well as the plug-ins themselves.

You could make all kinds of weird robotic voices.
You perhaps just want to try one of Gale's suggestions at a time.

I'd recommend trying the vocoder to start with (vocoder.ny)

Note that the vocoder uses two audio files, the voice and a carrier wave. To use the vocoder plug-in create a stereo file where the left channel is the voice, and the right channel is the carrier wave.

For general help on how to use audacity, see the links on this page: http://audacityteam.org/help/

For an example of a "robot voice" using the vocoder plug-in: http://easyspacepro.com/audacity/sfx/robot.mp3
This example also has a little reverb added (GVerb plug-in)

Just to clarify, the "carrier wave" is the sound that you vocode through. To work well it needs to be some kind of waveform containing a wide range of frequencies with a lot of energy. White noise fits this description. Another carrier wave that would work well would be a synthesized string chord.

Vocoder only works on unsplit stereo tracks. Example steps to make a stereo voice sound like a robot:

1 Record or import your stereo voice track
2 Click the Track Drop-Down Menu > Split Stereo Track to split the stereo track into left and right channels
3 Click the Track Panel of the right channel to select it, then click Generate > White Noise
4 On the left (upper) channel, click the Track Drop-Down Menu > Make Stereo Track to make an unsplit track again
5 Click the Track Panel once more to select the track, then Effect > Vocoder.... Try with the default settings at first. If you want to make the voice sound less intelligible, reduce the number of vocoder bands and vice-versa.

If your voice track is mono:

1 Click Project > New Audio Track to add a new track underneath your voice track
2 Click Generate > White Noise
3 Then follow steps 4 and 5 above

"Sawtooth" wave works well also.

how do u get sawtooth

"Generate menu > Tone..."
Then choose "Sawtooth"

Both the voice track and the carrier wave need to be mono tracks.
Put the carrier wave below the voice track
Click on the track name of the voice track and select "Make Stereo track"
Now apply the Vocoder.
