The Scribbler bot
The scribbler bot is essentially a drawing machine that converts digital information into a physical drawing. The bot is made up of a software component and a hardware component. The software component analyzes a picture taken by a web camera (or just about any other image source), creates a unique line drawing from that analysis, and exports a point list that corresponds to the points that make up the lines.

When I started thinking about CNC machines, I just wanted a computer-controlled machine that would be able to automatically drill all of the holes in the printed circuit boards that I made, for my Curve Tracer kits (see the link, above). But, the “good” commercially-available machines were priced higher than the amount that I could justify spending. So, I started thinking about what it would take to build one, myself. And, I didn’t want to build one that would cost almost as much as a commercial machine: Otherwise it might have been smarter to just BUY one, to begin with! So, I decided to add “low cost” as one of the design goals. I also expected to end up with one or more additional products to sell, as a result of this project, to (help) justify the time that I spent on it.
The ability to climb and descend stairs is one of the unexpected behaviors of this new home-brew off-road autonomous robot platform. The robot has a custom chassis and uses standard suspension and drive components scavanged from old R/C monster trucks. [

As Dr. Craig Kizewic worked on the infant, the heart rate began to drop and oxygen levels were declining, but quick work saved the baby. The baby was a new interactive medical simulator known as BabySIM. At 21 pounds and 28 inches in length, BabySIM has the physical characteristics of a three- to six-month old infant, but its fat little belly is stuffed full of computer parts. I wonder if there’s a less expensive design possible (it’s $54k) or an opensource BabySim project opportunity. [
