I'm a fairly inexperienced robot builder; I've only done a mod of an old R.O.B. I'm currently working on a new project though; the mod I did got me interested. Right now what I could use is some certifications so I can use some of the functionality on this site. :P ...Proof of my R.O.B. MOD, if needed, can be found on my website, http://opalassociation.net Thanks for your time.

Designing Stage for RIP (Robot in Progress that is probably doomed to die)

Since I'm building up money for this robot right now, I'm spending most of my free time designing.

I'm using Google Sketchup to design. Sorry, I don't have $10,000 for Autodesk or AutoCAD. :P

The robot will use differential drive; Two wheels in the back, with a castor of some sort in the front.

I'm using the Arduino Diecimila board to make my robot. The circuit is already designed, and is fairly simple due to my poor knowledge of circuits.

I thought I might just throw a IR Rangefinder sensor mounted on a servo on the robot and call it a day; But it seemed far too boring. And so, I'm buying all sorts of...fun stuff.

I'm buying a Pyroelectric sensor, which will detect humans or my cat, whichever I prefer. :P I'm also throwing in a sound sensor and CMOS camera if I can implement it properly with my horrible knowledge of circuits.

All of these sensors (minus the sound sensor) will be mounted in some way onto a head. Yes, like a robot head.

The head will be run by two motors; a 360 degree servo to rotate it left and right, and a sub-micro servo to tilt the head up and down. Designing the head has been a pain; I've had to go back and forth between what my design would look like and what's on http://mcmaster.com . If somebody could recommend to me a site that can cut HPDE (High Density PolyEthlane) to custom lengths, that would be appreciated. ;) I now have the design, the question is what I'm going to put on to be the cover for the head. Glass is too expensive; I can't find the right dimensions for clear or translucent tinted plastics. Oh well, I'll figure it out eventually.

Anyway... EARLY Designs:
