[FoRK] It's Time to Start 3D Scanning the World

No special hardware is needed to get very good 3D scans, once we get a little more CPU and improve the algorithms just slightly.  
Stereo vision, using just a single camera moved around a bit, is plenty to get pretty good data.

Imagine we bootstrap robots with just the basics, but great vision, memory, CPU, and networking.  We then crowd source teaching of 
shapes, objects, paths, patterns, jobs, etc.  And we would obviously have them share everything they learned on the robosocial 
RoboBook and RoboWiki.

What we really want to teach is basically the same thing that humans use to generalize and compress: prototypical objects that can 
be fitted to a wide range of instances.  You can do that with the many-examples method (which works best now for many things) or 
some combination of logical description and component recognition (probably better for things like chairs).

However, great databases of 3D objects would be great.
