Position Tracking Robot

I am designing a robot for my college project mainly having 5 sonar/ir sensors whose input is used to plot a 3-D graph to estimate the robot's position. Can anyone tell me which Arduino board will be suitable for this purpose?

Can anyone tell me which Arduino board will be suitable for this purpose?

For what purpose? Any of them can read from 5 sensors. Not a single one of them can display a 3D plot, without external hardware.

will be communicating with the pc. 3d plot to be generated on the pc

Ah, well, then, any Arduino will be sufficient. Any of them can read data from 5 sensors and send that data to a PC.

It seems like it will be even easier in your case, since you don't mention anything difficult like that robot moving.

the robot also has to move to positions input through pc. this input position will be compared with the current position of the robot and will decide a path to reach the destination :)

to generate it on PC using sensor redings

Is this anything to do with: http://arduino.cc/forum/index.php/topic,131898

yes

Right, then I'll merge them. Please don't cross-post.
