Thanks for all the responses.
Yes robust was that I was thinking, not really worried about price, more price per part, example I can afford $40 a paycheck to get a board an sdcard. (already have scooter motors, motor controllers, and several other parts to make the build an RC R2)
Yes I agree udp would be they way to go, I just used beowulf cluster because its a cluster environment i know of, do you know of a setup that would work better?
This will technically be my 6th or 7th I have build. Just wanting to venture into new areas.
My first was in 4th Grade I gutted out a old RC car that stopped working and progammed it on an old 486 linux box in C. it was programed to look for dark areas and backup and turn if it bumpped into anything. we called it the roach. I recently rebuilt it with a Arduino.
Then in all 4 yrs of High School I was in the robotics club and we build a robot each year do so a certain task, It was Remote controlled.
I am looking for something advanced to keep me busy, I don't expect to have it build and programed over night. I love to learn about new things and I figured If i was making a so called "mini" Beowulf Cluster why not re-purpose it after i was done with it.
ya I want the ability to add any feature to my Astromech I can think of. But yes thats what I was thinking is off loading some of the difficult tasks to other nodes. But I also didnt want to over load one cpu with too many instructions that it would cause it to responded slower.
On my School project my "central brain" or master node is going to be one of the ARM based Chromebooks and have plans to make that the user interface to the robot, probably set it up so I can ssh into it(wirelessly or wired) to change anything.
Over all I want a challenge, I want it to be robust, but basically I want to be able to take it to a star wars convention and let it loose and not run people over. and someone to be able to say hey R2 and it turn the dome the general direction it came from and squak to them or whatever.
I expect it to always be a work in progress, because I always wake up and think "oh that would be cool!"
And unlike other R2 builds the detail on my unit will all be practical. IE fan vents will have fan vents, Data port will be ethernet. etc
