How to interface with PC

I'm a beginner at robotics, but I do have a background in programming and some artificial intelligence and I'm planning to build an autonomous robot with an onboard computer. I may be able to use a Rasberry Pi, but I'm leaning towards a more powerful PC running (perhaps) Ubuntu. What would be a pragmatic (hopefully quick and easy) way to interface the PC with the inputs and outputs? Inputs would be ultrasonic sensors and probably either an infra-red camera or (inexpensive) laser scanner. Outputs would just be various motors to control wheels and an arm etc.

2d cad recomendation or help on linux?

Dear: LMR

Hello guys it is me Noah. Today I began to play with librecad on my ubuntu computer and I am really struggling with it. I downloaded another cad call QCad and it is far harder. Please guys this is coming from a guy who loves 3d modeling and never has used 2d before; So can you either help me get started with librecad like maybe a book recomendation or online tutorials, or recomend a new more user friendly software that is only for linux. TJust to let you know I am not willing to purchase any software. It all has to be free and no charge. Thank you.

Programming a Picaxe in Ubuntu

Well, a small comment in the shoutbox caused several guys to download Ubuntu. Good choice, I like it! Here's a walkthrough to programming a PICAXE in it.

 

STEP  1) Download the Linux Axepad here- http://www.rev-ed.co.uk/software/linaxepad_100.tar.gz

STEP 2)  Extract the files to a folder on your desktop called "LinAXEPad" or whatever you want to call it.

New Axepad for Linux Ubuntu users

The creators of Linux Axepad have created a .deb package for Ubuntu users. I was having issues with the other version off of rev-eds site. So far no issues with this one.

Once you have it installed you have to open a terminal and run "sudo linaxepad"
