So I decided I want to try and build my first robot. I went and picked up a copy of, "Robot Builders Bonanza" for begin learning some basic stuff. I haven't finished reading it all yet though. Unfortunately my skills in soldering and programming are zero. I did just finishing building my first PC, and that was much easier than expected

What I want to build is something like an automated mouse for my computer. I want it to be able to click squares in a small grid, in a random or fixed order, with a 30 sec delay in between each click. Ideally I would like to use a optical usb mouse that I have, and have everything contained inside of the housing. I saw this and thought it was interesting and built with a older mouse (

Any thought or input would be greatly appreciated.
Thanks
