cell phone remote control

[cognac]

I been trying to come up with ideas for long range communication with a semi-autonomous robot. Using the existing cell phone network seems like the best option. Wireless data transfer via cell phones isnt as reliable as I'd like, however I remember reading and hearing something about using a translator to translate the communication into a language of sounds.
Maybe using the audible voice range of cell phones which I think is ~300Hz to 3400 Hz (human voice is ~85-255 including male and female).

or something like a binary morse code I'm not sure

Looks like this

then using a series of h and lpf to divide the signal further, lower half for recieving upper end for transmitting. I really dont know just turning this idea around in my head.

I am no expert on this so if you have any ideas/comments please feel free to reply.

I came to this post looking for something similar to an idea that i had, and its realy similar to yours, I want to control a robot from a cellphone, y can connect the pc to the cellphone with bluetçooth, but my problem is to make th cellphone to command the robot, my idea was write a program in j2me, that use the audio output of the cellphone to comunicate with a microchip. The audio jack has at least 3 cables, uno for earth and the others for the wrigt and left ear. So, perhaps i can implement some protocol of comunication between the phone an the chip, with that wires.

IDEA:
----- CLOCK (throw this cable i send a clock signal to sync with the pic)
----- DATA (throw this cable i send the data bits, in sync with the clock)
----- EARTH (its earth there is nothing to explain)

Advantages: It will function on any phone that runs J2ME
Desadvantages: Perhaps it isnt realy fast, y have to tryit

If any one knows about something similar to this that is already working i will be waiting for the news.

If there is someone interested in tis proyect, please let me know to work together.
