Using Extruded Aluminum to telescope.

[Peter_Matteson]

Here are the pictures I promised. They are of the base and end of two different telescoping arms we have made. Our 1999 bot which has an Al monocoque design. And our 2003 robot which use extruded Al box. If you look carefully at the pictures labeled shoulder and wrist end you should be able to discover how this works.
