µP-Controlled Router Base
|
 Engineering
students at MIT have developed a hand-held computerized router that can precisely cut out or
rout practically any shape on any size wood (or plastic, foam, whatever) based on a digital
map of the pattern and the work surface. Strips of encoded tape are positioned on the material
and then the router follows the tape. Notice while watching the video that the router moves
around on the base unit. The operator's job is to keep the router near the center of the base
so it doesn't move against a hard stop at the edge of the base. This type of function is traditionally
performed with an X-Y plotter type system that automatically moves the bit across the work piece;
they can cost tens or hundreds of thousands of dollars, depending on the size. Depending on
your patience and skill, an entire 4x8-foot sheet of plywood could be handled if desired. I'm
guessing this device, once productized and made in China, will sell low end in Sears for about
$150.Posted August 2012 |
